SETI@home on SETI LIVE 01/22/2026

Thu, 22 Jan 2026 20:50:18 GMT

SETI@home Director Eric Korpela will be discussing the recent SETI@home results papers on the SETI Institute's SETI Live Podcast at 2:30 PM PST (5:30 PM EST, 2230 UTC).

SETI@home papers accepted for publication

Wed, 18 Jun 2025 03:23:30 GMT

Two papers on SETI@home will be published in The Astronomical Journal, a well-regarded scientific journal:

SETI@home: Data Acquisition and Front-End Processing describes SETI@home's data recorder, splitter, and client program. It covers the five detection types, their parameters and statistics, and the algorithm for finding them.

SETI@home: Data Analysis and Findings describes the back end (Nebula) and its results: RFI removal, candidate finding and ranking. It explains how artificial signals, or 'birdies', were used to optimize algorithms and estimate overall sensitivity.

Website outage

Thu, 03 Apr 2025 20:49:48 GMT

Multiple disk failure resulted in a web site outage. We think we've recovered almost everything from the web site, so it should be back up and running.

RIP Jimmy Carter

Mon, 30 Dec 2024 09:27:36 GMT

Carter wrote the following on June 16, 1977 and placed it in Voyager 1, which is the most distant human-made object from Earth:

This Voyager spacecraft was constructed by the United States of America. We are a community of 240 million human being among the more than 4 billion who inhabit the planet Earth. We human beings are still divided into nation states, but these states are rapidly becoming a single global civilization.

We cast this message into the cosmos. It is likely to survive a billion years into our future, when our civilization is profoundly altered and the surface of the Earth may be vastly changed. Of the 200 billion stars in the Milky Way galaxy, some – perhaps many – may have inhabited planet and spacefaring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message:

“This is a present from a small distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours. We hope someday, having solved the problem we face, to join a community of galactic civilizations. This record represents our hope and our determination, and our good will in a vast and awesome universe.”

--- Jimmy Carter, President of the United States of America, the White House, June 16, 1977

RIP Frank Drake

Sun, 04 Sep 2022 22:04:33 GMT

We are sad to report that SETI pioneer and originator of the Drake Equation passed away on September 2nd. Frank at the age of 92. Frank conducted the first SETI experiments capable of detecting radio signals at nearby stars distances, He continued to be a large influence on the field into his 90s.

Dan Werthimer had this to say:

If it weren't for Frank, I'd be filthy rich. When the first microcomputer chips came out in the early 70's I joined the Homebrew Computer Club, along with Steve Jobs and Steve Wozniak. Everybody in Homebrew became ultra-rich, except me.

While other homebrewers were designing and selling the first home computers, I spent my time figuring out how to utilize the first computer chips for SETI experiments, thanks to Frank. I didn't become rich, but instead I was inspired by Frank to work on some of the most fundamental questions we have as humans. He taught me so much - I was incredibly fortunate to work with Frank on many SETI experiments for 45 years. Frank's insights led to optical SETI, SETI@home, and most recently, while in his 90's, Frank helped pioneer PANOSETI.

Frank was a wonderful friend, mentor, and brilliant collaborator. If Earthlings ever find ET, we'll have Frank to thank.

Another bittersweet milestone.

Bryon Leigh Hatch and Arecibo have passed on.

Wed, 02 Dec 2020 18:59:36 GMT

We got two pieces of really bad news yesterday. Byron Leigh Hatch, founder of the Carl Sagan team, all around smart and thoughtful guy, and a setizen since shortly after SETI@home began in 1999, passed away in August. There is a thread for leaving remembrances here. He will be missed.

And, of course, we were informed of the collapse of the elevated structure at Arecibo. It was clear after the second cable broke, the structure would come down soon. As much as we were unhappy that the repair efforts had to be abandoned because of the danger, it's clear now that it was the right call. It's our hope that we will find national support for building new scientific facilities on Puerto Rico in the near future.

SETI@home hibernation

Mon, 02 Mar 2020 21:16:23 GMT

On March 31, the volunteer computing part of SETI@home will stop distributing work and will go into hibernation.

We're doing this for two reasons:

1) Scientifically, we're at the point of diminishing returns; basically, we've analyzed all the data we need for now.

2) It's a lot of work for us to manage the distributed processing of data. We need to focus on completing the back-end analysis of the results we already have, and writing this up in a scientific journal paper.

However, SETI@home is not disappearing. The web site and the message boards will continue to operate. We hope that other UC Berkeley astronomers will find uses for the huge computing capabilities of SETI@home for SETI or related areas like cosmology and pulsar research. If this happens, SETI@home will start distributing work again. We'll keep you posted about this.

If you're currently running SETI@home on your computer, we encourage you to attach to other BOINC-based projects as well. Or use Science United and sign up to do astronomy. You can stay attached to SETI@home, of course, but you won't get any jobs until we find new applications.

We're extremely grateful to all of our volunteers for supporting us in many ways during the past 20 years. Without you there would be no SETI@home. We're excited to finish up our original science project, and we look forward to what comes next.

Low available work.

Sat, 18 Jan 2020 18:51:01 GMT

For a couple of reasons, the result table has grown to the point where it no longer fits in main memory. That has been slowing the validators and assimilators, which is causing the result table to grow further.

We'd like to get it down to a manageable size before our Tuesday outage. To that end we are throttling work generation to a rate at which the table size is shrinking. We hope that this rate will increase as the table gets smaller.

So for the next few days work will be hard to come by (but not zero).

Some server issues today...

Fri, 20 Dec 2019 17:10:04 GMT

It's the Friday before a holiday week and the servers know it.

The file system containing the beta project uploads directory is having problems, so beta is down until further notice.

This problem may be affecting the rate at which the main project can handle results, so the validation and assimilation queues are getting large, which may affect the rate of work generation.

New paper on observing "Clarke Exo-belts"

Wed, 04 Dec 2019 19:44:43 GMT

Dr. Korpela and his colleagues Prof. Shauna Sallmen and Ms. Kaisa Crawford-Taylor have published a new paper today in the Astronomical Journal about whether astronomers be able to detect belts of satellites circling planets around other stars. Unfortunately, the answer is that even the thickest satellite belts will be very difficult to see with current technology. Even the James Webb Space Telescope will find it difficult.

If, like most sentient beings in the Galaxy, you don't have a subscription to the Astronomical Journal you can see a preprint of the article at arXiv.org.

Article on SETI@home's 20th anniversary

Sat, 25 May 2019 13:45:15 GMT

An article by Ben Lindbergh in The Ringer discusses the history and status of SETI@home as it turns 20.

20 years and counting!

Fri, 17 May 2019 17:39:43 GMT

Happy Anniversary! On this date in 1999, SETI@home came online. Since then millions of our volunteers have helped us sift through petabytes of data from multiple radio telescopes. ET still hasn't shown up to the party.

We're not discouraged. We're able to examine less than a tenth of a percent of the radio spectrum, over only 1/3 of the sky and a limited number of additional stars. But our capabilities are increasing every day. In 1999 it took up to a week to process a single workunit on a home PC. Now, on a machine with a GPU, it might only take a few minutes to do a far more detailed and more sensitive analysis. Who knows what the next 20 years will bring?

I'm glad we have the replica.

New SETI Perspectives article

Tue, 12 Mar 2019 21:18:25 GMT

Richard M Lawn has posted another interesting article to the SETI Perspectives forum. This one is about the mysteries of Fast Radio Burst (aka FRBs), possibly some of the most distant explosions ever seen.

We're back up.

Thu, 07 Mar 2019 00:51:29 GMT

Hopefully there won't be any further problem.

Our attempt to upgrade the memory on Oscar (the BOINC database machine) and Carolyn (the replica database) took a bit of DIMM swapping to find pairs of DIMMs that worked. Carolyn is still short two DIMMs (32 GB), but we didn't want to extend the outage any further to try to get it up to the full 192 GB.

We might try to max out Carolyn during the outage next week.

[edit]And as is usual after a long outage, we've got a large number of hosts out there starving for work. It'll take a little while before "no work" messages start to get less frequent.[/edit]

Download server glitch

Fri, 01 Mar 2019 21:00:09 GMT

We had a problem with one of our download servers that was slowing down downloads and slowing down work generation. We've fixed the problem, but there are lots of people out there trying to download. It'll probably be a while before our downloads aren't swamped with requests.

Work ready to send has started trending back up, so we shouldn't end up with a work shortage.

BOINC Open Source Project looking for experienced MacOS developers

Wed, 20 Feb 2019 17:47:19 GMT

The Berkeley Open Infrastructure for Network Computing (BOINC) system is the software infrastructure used by Einstein@Home and many other volunteer distributed computing projects. The BOINC Open Source Project is looking for volunteers to develop and maintain the BOINC client on macOS. The BOINC Client and Manager are C++ cross-platform code supporting Microsoft Windows, macOS, Linux, and several other operating systems. We currently have a number of volunteer developers supporting Windows and Linux, but our main macOS developer is winding down his involvement after many years. He is prepared to help a few new macOS developers get up to speed.

If you have macOS development experience and are interested in volunteering time to help support and maintain the BOINC macOS client please have a look at the more detailed description here: https://boinc.berkeley.edu/trac/wiki/MacDeveloper

If you want to help, please sign up to the BOINC Developer email list here: â€‹https://groups.google.com/a/ssl.berkeley.edu/forum/#!forum/boinc_dev.

If you are not a macOS developer, but have other skills and are interested in contributing to BOINC, the link above also has more general information.

Thank you!

Storage machine crash....

Fri, 08 Feb 2019 21:34:28 GMT

A machine that was holding 15% of our outgoing workunits has crashed and refuses to start back up. Short term it means that attempts to access those workunits will cause an error until the workunit is marked as bad.

Sorry for the incovenience.

Slow server for the next 8 hours or so...

Wed, 30 Jan 2019 03:33:02 GMT

GeorgeM, the machine that holds the data that you download, decided that it was time to verify that the RAID array is in good shape. That will slow down disk access until the verify procedure is complete. The main effect is slowing down the rate at which work can be created. It's likely that we'll run out of work in the next hour or so. Things should recover automatically when it's done.

Little bits of previously unfinished data.

Fri, 11 Jan 2019 18:28:11 GMT

You may have noticed occasional bits of data from years past showing up in your queue. While running a completeness check I noticed some files that had never been completely analyzed. Some may have fallen through the cracks. Some may just be bad data that never made it through the splitters. I'm going to trickle them into the queue when the Arecibo queue is empty, just in case.

Science database crash...

Mon, 07 Jan 2019 00:17:40 GMT

We had a minor science database crash today that brought work generation to a halt. Everything appears to be OK with no data losses. We should [be] entirely back up at this point, but I'll keep checking things out.

Revised scale of significance of ET detection published.

Wed, 25 Jul 2018 15:47:05 GMT

A group of SETI astronomers led by Duncan Forgan, and including myself and BSRC director Andrew Siemion, has published a revised version of the Rio Scale. The Rio Scale is designed to predict the public impact a signal would have, like the Richter scale does for earthquakes. The prior version of the Rio scale, in addition to being rarely used, tended to overestimate the impact of low quality or low significance reports of detection.

Now all we have to do is convince other SETI astronomers and the press to use it.

There is a related article at GeekWire.

A calculator for Rio 2.0 scores in now available here.

Dropped packets

Mon, 30 Apr 2018 17:23:04 GMT

The UC data center switched over to a new firewall this morning. Since then packets into and out of the data center have been suffering drops. The Data Center staff is debugging the problem, we'll probably be dropping packets until it's resolved.

Unexplained database slowness

Sat, 31 Mar 2018 06:11:02 GMT

The database has gotten hung up a couple of times with slow queries. I've restarted it once and that seems to have helped. It'll take several hours to be sure.

If that didn't solve the problem, it probably means the index the server uses to choose workunits to send has gotten corrupted. If I need to rebuild it, we'll probably be down most of tomorrow while I do so.

Slow network connection to Green Bank

Mon, 29 Jan 2018 18:45:35 GMT

Something is happening to the network connection between Green Bank and Berkeley that is slowing down the rate at which we can transfer data for splitting. We've opened a trouble ticket with campus networking services. Hopefully they will be able to find and fix the problem quickly. Until then, work may be in short supply.

Long outage...

Wed, 24 Jan 2018 07:17:44 GMT

The outage ran long today because we needed to run down to the data center to swap some bad drives with new ones and reboot a few of the machine to pick up kernel and mysql updates.

Sorry for the delay.

Special Fundraiser for Parkes Data Store and GPU development system

Thu, 07 Dec 2017 19:15:11 GMT

Thanks to our collaboration with Breakthrough Listen and their international colleagues, we will soon have the ability to access data recorded at the Parkes Radio Telescope in Australia. For the first time, this will give us full-sky coverage, including the southern hemisphere, in our search for ET. However, due to the enormous amount of data that the 13-beam receiver at Parkes can generate, we will require extra hardware to store and distribute it. We need your help to purchase this.

Thanks to some special offers, one from the Hanson family in memory of Robert W. & Mary P. Hanson, one from Richard Haselgrove in memory of his mother, Jenifer Leech, and one from Mr. Kevvy, we have the possibility to match donations which will allow us to purchase the Parkes Data store server (~$34K) and the GPU development systems (~$10K) we will need for the coming year. For every dollar you donate in this special fund raiser, Mr. Kevvy will match it, the Hanson Family will match it with two, and Richard Haselgrove will match it with two more. That means for every dollar you donate we'll get six dollars towards the purchase of these servers!

Because this is a special fundraiser we'll have special notation on your account page and on the forums. The 12TB disk drives in the Parkes Data Store cost $450. One sixth of that is $75. So, a donation of $75 or more gets you a disk drive icon. The GPUs in the GPU development machine that we will be using for our recording systems at future telescopes are $1500 each, so a donation of $250 or more will get you a GPU icon. And as always, any donation of $10 or more will get you a green star.

But in the end, it's not about the icons: it's about getting the data and making a discovery for the ages. Your help, whether by crunching data or by donating, is always appreciated.

Splitters off, again :(

Wed, 06 Dec 2017 05:39:33 GMT

I had to turn the splitters off, again. I underestimated the rate at which we were creating work (damn moveable decimal points!). I thought we could go without adding more space to the database until we had time (tomorrow morning) to delete the old database spaces.

I was wrong, we really zoomed through the files on disk, and we ran out of space. Deleting database spaces is dangerous, so I really want Jeff to check the command script before it gets run. That won't happen until morning. But once it does we'll be back in operation.

Hopefully most SETIzens won't even notice this short absence of work.

Berkeley SETI Research Center undergraduate research internships, summer 2018

Tue, 05 Dec 2017 01:23:37 GMT

Applications are invited for 10-week paid undergraduate research internships at Berkeley SETI Research Center for summer 2018. BSRC is a
world-leader in the search for extraterrestrial intelligence â€“ the quest for a scientific answer to one of humanityâ€™s oldest questions: Are we
alone in the Universe? Housed in the Astronomy Department at the University of California, Berkeley, the team at BSRC leads the science
program for the $100-million Breakthrough Listen project. Our scientists and engineers are pioneers in the development of software,
instrumentation, and science strategy for the search for intelligent life on other worlds. We have access to substantial amounts of time on
the planetâ€™s largest telescopes, connections to leading players in industry, and weâ€™re based in one of the worldâ€™s premiere astronomy
research institutions. Weâ€™re also psyched that we get to wake up each day and hunt for aliens.

Current sophomore, junior, and senior undergraduates (including non-US citizens) studying at a degree-granting institution in the US are eligible to
apply. Around 5 - 7 positions will be available. A stipend of $20 / hr (up to a maximum of $8000) will be provided. Details and links to the application form are at https://seti.berkeley.edu/Internship.html

We're generating work again.

Sat, 02 Dec 2017 07:19:51 GMT

It took a bit longer than I thought it would, but we're back online. It'll probably be a few days before we have a full ready-to-send queue.

Now we can get back to finding ET.

No work. Database issues.

Wed, 29 Nov 2017 21:41:36 GMT

At first I thought the restart on Tuesday had solved our database problems. I guess I was wrong. It only fixed some of them.

We've hit yet another hidden limit in our Informix science database. The good news is that we know how to fix this one. The bad news is it will take a little while.

We don't have to wait for the full fix before starting to split again, but the point at which we can split will probably be sometime tomorrow. Until then, we only have a few re-dos and a little bit of astropulse to do.

Richard Lubrich has passed away.

Wed, 29 Nov 2017 01:43:24 GMT

Long time setizen, Richard Lubrich (Dr. C.E.T.I., aka Dr. SETI, aka nobody) passed away today. Richard was a fixture on the forums from our earliest days. He was a great friend to SETI@home and will be greatly missed.

Database slowness

Sat, 11 Nov 2017 00:09:26 GMT

We're having some as yet unexplained slowness with the our BOINC database. There don't seem to be any hardware issues. Temperatures are running normal and all the drives seem good. Yet for some reason the query that fills the "ready to send" queue is running about 10 times slower than it normally does.

Until I get it fixed, it means that on average we're sending out 3 workunits a second rather than 30+.

I'll let you know when I've got it figured out.

SETI@home 2017 fundraising drive has begun.

Fri, 03 Nov 2017 17:29:31 GMT

We've started our annual fundraising drive to help raise the money we need to keep SETI@home running and expand it to new telescopes. Your computers provide us with the power to analyze this data, but your donations are an important part of keeping us operating.

If you haven't yet received your fundraising letter, you can preview it here. You can donate at https://setiathome.berkeley.edu/sah_donate.php.

Thanks for keeping SETI@home going!

BSRC Student Travel Fundraiser

Mon, 02 Oct 2017 18:10:26 GMT

Berkeley SETI Research Center is holding a fundraiser to raise $7000 to send our student interns to conferences to present their work.

Weâ€™ve been working with some great students at Berkeley SETI, and weâ€™re optimistic that some of them will become the scientists and engineers who lead the field in future and maybe even find the signal weâ€™re searching for. In the meantime they have been doing amazing work and weâ€™d like to send them to academic conferences to present their results, and for their own professional development. If you would like to help with this effort, we are running a crowdfunding campaign at https://crowdfund.berkeley.edu/SETItravel - every donation counts! We also have some fun perks including the chance to ask questions to members of the Berkeley SETI team, and to attend a party in our lab.

Although this does not directly benefit SETI@home (our annual fundraiser will start in a couple weeks), it's a worthy cause. I'll be contributing!

Arecibo Status

Thu, 21 Sep 2017 17:11:28 GMT

I've been asked by several people to post a status update on the situation at Arecibo following hurricane Maria's passage.

Unfortunately, at this point we haven't gotten any news. The last information we have is from a couple hours prior to when the eye passed Arecibo. That report said all the employees were accounted for and in sheltered buildings.

Since then we've had no news. That's understandable. With power out on the whole island, electronics communications aren't going to be possible for some time. Heavy rains are still expected today, so I'm sure that the primary concern is still keeping everyone safe. Assessment of any damage will take time.

Let's hope that everyone is safe, that their homes are intact, and that any damage can be repaired quickly.

Data from "Tabby's Star" is flowing.

Thu, 07 Sep 2017 16:36:28 GMT

For those who didn't recognize the name KIC8462852 in their work unit names, this data comes from GBT observations of Tabby's Star (aka Boyajian's Star, aka WTF-0001, aka the Weirdest star in the galaxy). This is not yet the full data set, which lives at Penn State, it's some test on-target/off-target observations that we're checking out.

You might also notice another change. We've doubled the size of our work units which will reduce our quantization noise by 34%, and, depending on the strength of other noise sources, could give us as much as double that as a sensitivity increase.

SETI.Germany Wow!-Event

Wed, 02 Aug 2017 07:47:46 GMT

A 3D tour of the Green Bank Telescope.

Wed, 28 Jun 2017 18:24:15 GMT

We took a GoPro Omni 360 VR camera up to the top of the Green Bank Telescope, the largest steerable radio telescope in the world. Join us on Part 1 of our journey, as we check out the telescope wheels that each carry more than a million pounds of weight, and learn about the 2004 individually controllable panels that make up the surface of the dish, which is larger than a football stadium.

Help us improve RFI removal and scoring

Sat, 10 Jun 2017 23:29:55 GMT

The SETI@home back end is getting closer to completion.

Our algorithms for removing RFI and finding repeated signals work fairly well.
We can inject "birdies" (synthetic signals) to measure how well they're working.
We've developed tools for browsing, drilling down, and visualizing signals and candidates.

At this point we need to manually scan lots of results, looking for cases where our algorithms don't seem to be working perfectly. If you like, you can help us with this.

Jodrell Bank to partner with Breakthrough Initiatives

Wed, 31 May 2017 22:46:20 GMT

At Berkeley SETI Research Center, we've long been friends and collaborators with Professor Michael Garrett and the team at Jodrell Bank. We're delighted to continue our collaboration as the Breakthrough Initiatives announce a formal partnership with Jodrell in the search for intelligent life beyond Earth: https://breakthroughinitiatives.org/News/11

Although this partnership doesn't involve data from telescopes at Jodrell flowing to SETI@home (at least at the present time), the sharing of data, algorithms, and strategies will benefit the science programs at Berkeley and Jodrell, as well as at other telescopes involved in Breakthrough Listen and in SETI in general. You can seen an interview with Mike, recorded a few weeks back, at https://youtu.be/ZRMiuCFACCw, and take a 3D tour of the Lovell telescope and control room at Jodrell at https://my.matterport.com/show/?m=B8UZb1joxsG.

Free Speech and SETI@home

Thu, 27 Apr 2017 03:50:26 GMT

Once again I need to explain our policies on free speech, as I've been getting lots of nastygrams both here and on twitter and facebook.

First, let me explain our relationship to the UC Berkeley administration. Despite the fact that I met with the Chancellor once for about 15 seconds, the UC administration neither knows nor cares that SETI@home exists. Threats of quitting SETI@home or withholding donations will be about as effective as kicking a stray dog because you don't like something the dog catcher did. They won't notice. They don't care. They get no direct benefit from SETI@home, so here will be no effect on them, or the on University. We could shut off our servers tomorrow, and nobody in Sproul Hall would notice a thing.

So here are our project commandments on free speech.

0. Thine speech is free as in freedom, not free as in beer.
1. Thou mayst speak thine mind.
2. Thou shalt do so in the appropriate forum.
3. Thou shalt recognize that speech has consequences to thine self and to others, some legal, some financial, some painful.
4. Thou shalt not force others to pay for the delivery of or the consequences of speech they may not agree with.
5. On public SETI@home forums, thou shalt use language a parent would not mind their 12 year old hearing.
6. Failure to obey the forum rules will result in moderator action. If thou dost not understand, see thou commandment 4.

In other words, if you want to be heard on the current controversy, try the Politics forum. Then use twitter, facebook, instagram and whatever social media you want. SETI@home in general and me in particular have no power to effect change of any sort.

It sounds like there's still going to be a riot in Berkeley tomorrow because a group of white supremacists and a group of left wing anarchists are ignoring commandments 2, 3, and 4. The people of Berkeley and the people of California will be picking up the tab for their "freedom of speech" whether they want to or not. And personally, I think that's what's been missing from the whole discussion.

Where we get the data

Mon, 10 Apr 2017 23:06:21 GMT

Thanks for helping us analyze Breakthrough Listen data from the Green Bank Telescope! Berkeley SETI engineer Dave MacMahon takes us behind the scenes into the server room at Green Bank where the Listen instrument lives, and we also interview Green Bank director Karen O'Neil about keeping computers cool in our latest video: https://youtu.be/-gQocykdo1Y

We're back online

Sat, 01 Apr 2017 03:37:03 GMT

And with some incredible luck we didn't lose any entries in the pulse signal table at all.

Whew!

Unexpected outage (March 30-31)

Thu, 30 Mar 2017 23:43:29 GMT

We've found some corruption in a part of our science database that holds the power vs time profiles of detected pulses. We're running some table checks to see if we can localize the problem and come up with a solution that minimizes the lost workunits that need to be redone.

Science progress reports

Fri, 10 Mar 2017 08:15:57 GMT

We're moving closer to completing the analysis of our 18 years of Arecibo data. Recent work has given us a good handle on RFI removal. See the Nebula blog for details.

New SETI@home donation project on Bitcoin Utopia

Sat, 07 Jan 2017 00:35:08 GMT

We've started a new mining effort on Bitcoin Utopia. If you've got mining equipment and want to help out, please join the effort.

The ~5 bitcoins that were donated last year went primarily to buying replacement hard drives. With the number of drives we have running we lose quite a few over the course of a year. It was nice not to need to dip into cash to replace them.

Problems with centurion

Fri, 06 Jan 2017 20:25:26 GMT

We're having some problems with centurion, the computer holds the Breakthrough Listen data and does our Breakthrough Listen splitting. Correction will probably require an OS upgrade.

Because of this GBT data will be scarce over the weekend.

Breakthrough Listen observations of HD 164595

Tue, 30 Aug 2016 19:37:24 GMT

The Breakthrough Listen team has posted their archival search for emission from HD 164595 and the initial analysis of their recent observations of that target.

"Baffling" "signal" "from HD 164595" is probably none of the above.

Mon, 29 Aug 2016 17:50:30 GMT

I'm sure that many of you have seen the news reports of a "SETI signal" detected from the star HD 164595

I was one of the many people who received the the email with the subject "Candidate SETI SIGNAL DETECTED by Russians from star HD 164595 by virtue of RATAN-600 radio telescope." Since the email did come from known SETI researchers, I looked over the presentation. I was unimpressed. In one out of 39 scans that passed over star showed a signal at about 4.5 times the mean noise power with a profile somewhat like the beam profile. Of course SETI@home has seen millions of potential signals with similar characteristics, but it takes more than that to make a good candidate. Multiple detections are a minimum criterion.

Because the receivers used were making broad band measurements, there's really nothing about this "signal" that would distinguish it from a natural radio transient (stellar flare, active galactic nucleus, microlensing of a background source, etc.) There's also nothing that could distinguish it from a satellite passing through the telescope field of view. All in all, it's relatively uninteresting from a SETI standpoint.

But, of course, it's been announced to the media. Reporters won't have the background to know it's not interesting. Because the media has it, and since this business runs on media, everyone will look at it. ATA is looking at it. I assume Breakthrough will look at it. Someone will look at it with Arecibo, and we'll be along for the ride. And I'll check the SETI@home database around that position. And we'll all find nothing. It's not our first time at this rodeo, so we know how it works.

Arecibo still threatened with closure.

Thu, 09 Jun 2016 23:15:35 GMT

Recently the NSF announced its intent to start the process which could lead to the partial shutdown, mothballing, or complete disassebly of the Arecibo Observatory. As most of you know, this is not a new discussion in the scientific community. Several years ago we had asked you write letters to Congress in hopes of averting this fate.

A petition has been started on whitehouse.gov to ask the President to ensure it is funded. I'm pessimistic about the chances that it will change anything, as the President cannot change Congressional budget priorities, and only has limited ability to move money between NSF programs. However, bringing attention to the issues of science funding in this country cannot hurt.

Thanks for helping!

Mon, 25 Apr 2016 19:03:11 GMT

We couldn't do any of this without you. Our search relies on the generosity of those who donate their computing resources and electricity, their coding skills, and also financial help to make what we do possible. Any and every contribution counts, and we appreciate all of you. While we are not funded by big government grants, we are fortunate to be based at one of the world's leading public universities, where one of our most precious resources is the bright young minds who will be the scientists and engineers leading the search in the years to come.

So we invite you, if you feel motivated to do so, to help us with the resources to set up an undergraduate lab with new software-defined radio tools to help train our undergrads in the tools of the trade. To get an idea of how engaged these students are, check out our interview with Kyle at https://youtu.be/PIJ6TkM46wE. And if you'd like to support our work, please visit https://crowdfund.berkeley.edu/project/1704. But whether or not you choose to contribute financially, we are so grateful for all of you that have chosen to be a part of SETI@home as we attempt together to answer humanity's biggest question. Thanks!

Article about distribution of Breakthrough data.

Fri, 15 Apr 2016 00:01:13 GMT

Inverse.com has published an article about our distribution of Breakthrough Listen data.

Breakthrough Listen data now flowing.

Tue, 12 Apr 2016 18:04:28 GMT

Happy Yuri's Night #55, the 55th anniversary of Yuri Gagarin's historic first space flight on April 12, 1961.

In celebration, we're starting distribution of Breakthrough Listen data from the Green Bank Telescope today. No intervention is necessary on your part. The main difference you will see is a change in your screen saver graphics, if you have them running. We'll still be distributing Arecibo data as well, so that won't change.

The Breakthrough Initiative is also distributing raw data in multiple formats, so you can write your own analysis code if you'd like.

You can read about it in this press release.

New video: BSRC intern Kevin Luong

Fri, 22 Jan 2016 20:51:10 GMT

Kevin Luong joined Berkeley SETI Research Center as an intern in summer 2015. Kevin worked with David Anderson to revise the NTPCKR system to run on cloud computing servers. There are still a few kinks to sort out, but if it works, this should let us run our data base through NTPCKR in a few weeks instead of more than a year. Kevin transferred to UCLA in the fall, but is continuing to work with SETI to explore cloud computing for other projects.

We'll be launching an expanded undergraduate internship program soon. Details will be announced later this year.

SETI@home Version 8 has been released.

Fri, 01 Jan 2016 17:59:48 GMT

SETI@home version 8 has been released. This version finally gives us the ability to process data from multiple sources, including the Green Bank Telescope. That means we'll be ready for data from Breakthrough Listen when it's available.

We're releasing the versions for CPUs first. We'll release versions for graphics processing units (GPUs) and Android devices as they come available. We're releasing slowly so as not to overtax our download server. This update will happen automatically, unless you use a special version you got from another web site.

We've also made small changed to our science code to improve the Gaussian fitting routines. This means version 8 results are not compatible with version 7. So if you use a version of SETI@home you got from another site, or if you compile your own version, you'll need to get or build a version 8 application. I'm sure link will be made available in the Number Crunching forum.

A shout out to the volunteer developers (especially Urs, Jason and Raistmer) and all the beta testers for helping out.

Happy New Year!

Did SETI@home ever find aliens?

Fri, 30 Oct 2015 16:13:45 GMT

While still working our way through a lot of data, this article asks the question: Did SETI@home ever find aliens?

Probably not aliens, but ...

Thu, 15 Oct 2015 17:19:54 GMT

â€œAliens should always be the very last hypothesis you consider, but this looked like something you would expect an alien civilization to build.â€

False News Report

Tue, 31 Mar 2015 15:17:01 GMT

Over the weekend a false news report from a known source of false news reports reported that we had detected an extraterrestrial signal. Of course, if we had, known sources of real news reports would also be carrying the story.

In other words, no such luck.

Prof. Charles Townes has passed away.

Tue, 27 Jan 2015 23:16:09 GMT

We were saddened to learn that colleague Professor Charles Townes died this morning, January 27th, at the age of 99. A professor at UC Berkeley since 1967, Townes had a long and distinguished career, winning the Nobel Prize in Physics in 1964 for work that led to the development of the laser. He was active in research as recently as last year, making regular visits to his office at UC Berkeley's Space Sciences Laboratory, and to Mount Wilson Observatory where he worked to develop the Infrared Spatial Interferometer telescope. His broad research interests included the search for extraterrestrial intelligence - as co-author of a 1961 paper, he was one of the first to discuss interstellar communication using lasers. This gave rise to the rapidly growing field of optical SETI, including searches currently underway at UC Berkeley. Prof. Townes also served as an Advisory Board Member to the new Foundation for Investing in Research on SETI Science and Technology. We will miss him here at UC Berkeley, and send our condolences to his wife Frances and family.

Marvin crashed

Sun, 21 Dec 2014 04:46:29 GMT

It appears that the root partition filled on marvin (rapidly) while I was AFK, for no reason that I am aware of, which caused it to crash. Nobody is at the colocation facility right now, so the astropulse DB is down. I'll try to get remote accesses for a reboot, but chances are that marvin is down until monday morning.

New Data from AO

Fri, 05 Dec 2014 17:54:33 GMT

The four disks from AO have arrived - about 5TB of data. I have queued them up for pre-processing (radar blanking) so new SETI@Home workunits should be going out soon.

Database Rebuild Status update.

Tue, 02 Dec 2014 02:22:45 GMT

We've now inserted 231,770,000 of the 306,362,193 AstroPulse signals into the database. Over the last week the insert rate has slowly declined from 1.5 million per hour to 870,000 per hour. At that rate we're looking at another 86 hours (+24 for index building), which means Saturday morning (US Pacific time).

On the plus side, Arecibo has four full drives of data that they can send us, so there might be SETI@home work before then if we're really lucky. I'll be posting updates in the Tech News forum through out the week.

Status Update

Wed, 26 Nov 2014 04:53:07 GMT

If you haven't been checking the tech news, here's the current status. We're rebuilding the Astropulse database. The current rate is an anemic 1.5 million rows per hour. There are 220 million rows left to do, which translates to 140 hours. Then I estimate it will take 24 hours to build the one remaining index necessary to create new work. That adds up to a week. I don't really understand why this is so slow. The disk array should easily handle twice that rate.

Sorry the news couldn't be better. There's always the SETI@home fundraiser at bitcoinutopia. Or you could choose a worthy backup project

Running out of workunits

Thu, 13 Nov 2014 18:25:49 GMT

We are likely to (temporarily) run out of workunits to process as soon as this weekend. Please read this recent news item from Eric Korpela for further explanation leading up to this. We are currently solving various database issues, developing a new splitter so we can start processing our Green Bank Telescope data, and hunting for tapes that haven't fully been processed to get out of the current drought.

NRAO telescopes will be taken offline due to government shutdown

Thu, 03 Oct 2013 17:11:45 GMT

We've received notice that the NRAO telescopes at Greenbank will be shut down at 5pm on Friday if the government shutdown continues. We don't have any immediately scheduled observations there, so this should not affect us in the short term.

We have not yet heard of any impact on Arecibo, but since it is operated under contract rather than being directly operated by the government, we are hoping observations there will continue.

We are now mostly recovered from a campus wide power outage.

Tue, 01 Oct 2013 21:48:07 GMT

Last night there was a power outage that affected the entire Berkeley campus. The data center, where our servers are located, does have facility wide UPS so all servers stayed up. Unfortunately, the data center air conditioning did not stay up. Machines were getting hot, so the data center staff had to bring them down.

Android Beta Testers Needed

Thu, 05 Sep 2013 00:33:04 GMT

We're beta testing the Android version of the SETI@home application and we're looking for more testers to speed up the process. If you'd like to help, install the Android version of BOINC through the Google Play Store or the Amazon App Store. Then when asked to join a project enter http://setiweb.ssl.berkeley.edu/beta as the project URL.

note: The beta project does not have access to SETI@home user accounts. Unless you're already using the beta project, you'll need to create a new account there.

What's new about SETI@home v7

Mon, 10 Jun 2013 22:44:29 GMT

Dr. Korpela has posted his promised summary of what is new in SETI@home v7.

AVG 2013 virus scanner false positive on SETI@home 7 for Windows

Thu, 30 May 2013 17:45:58 GMT

The AVG virus scanner heuristic virus detection method reports a false positive for SETI@home version 7.00 on windows. This alert doesn't not indicate an infection with a known virus, but indicates that the application contains code that the virus scanner considers to be suspicious. AVG 2012 apparently does not report any issues.

We believe that this alert is related to the method we used to compress the executable in order to save network bandwidth. We are examining how we can resolve the problem. Until then the best strategy is to click "cancel" or "ignore" to the AVG warnings.

SETI@home Version 7 has been released

Thu, 30 May 2013 00:39:58 GMT

Your BOINC client should automatically download it in the next few days. No need to abort any current work you are doing.

We've released versions for Windows, MacOS and Linux, and four versions for NVIDIA graphics cards running under windows, and versions for ATI graphics card running under Windows and Linux.

My thanks to the KWSN/lunatics folks for getting this done and especially to Raistmer, Jason, Josef, Urs, Claggy, Mike, Richard, and too many beta testers to name.

Tomorrow I'll post explaining why we wanted version 7 and what's different about the analysis it does.

Server Relocation

Wed, 20 Mar 2013 21:56:25 GMT

We are moving most of our servers to a colocation facility with better cooling, power, and network, which should improve uptime in general. This procedure will start on Monday, April 1st at 08:00 (PDT) and should take 3 days to complete, during which our entire project will be unavailable.

Successful Lab Repairs

Sun, 24 Feb 2013 17:06:21 GMT

The entire lab was shut down this past weekend for electrical repairs. We came back on line Sunday morning (Feb 24th).

Wed, 28 Nov 2012 19:47:46 GMT

Problems with timeouts will continue to occur, but less frequently, we hope.

SETI@home scheduler is down until further notice.

Fri, 23 Nov 2012 19:17:54 GMT

Scheduler crashes have continued, so we'll be down until we've isolated and solved the problem.

We are thankful for....

Thu, 22 Nov 2012 21:45:15 GMT

We're thankful for you, our volunteers, who continue to donate your time, computers and money to keep SETI@home up and running and improving.

Scheduler crashed.

Thu, 22 Nov 2012 17:30:12 GMT

The scheduler will be down until someone can get to the lab to reboot it. I'll try to convince Angela to let me go in once the turkey is in the oven.

Continued server problems.

Mon, 19 Nov 2012 01:02:54 GMT

We're continuing to have issues due to a database problem early last week and a botched attempt to fix it.

The problem is that the result and host tables in the database have grown large enough, and hosts have gotten fast enough that the lookup of result in process for a host and the enumeration of new results to send don't finish before the web connection times out either on the server or the client side. This resulted in hosts being assigned large number or results to compute without the transaction that tells them about these results being completed. The host. think it received no results would then contact the server for more results, which it would again not receive.

This isn't a hardware problem. The database currently fits in memory and the processors are fast. We've just crossed a threshold where each host computes fast enough that host queues and the result table have become large enough to cause this problem. To solve it, we've put per host limits on results in process back in place. But hosts that are having this problem will probably continue to have it until the average number of results per host has fallen to a workable level. That could take weeks.

For a more permanent fix, we plan do more work in each result by quadrupling the size of the workunits. But that fix will probably take months to implement and test.

We are recovering from a database crash

Wed, 24 Oct 2012 22:56:13 GMT

The main boinc database suffered a crash this morning. We are back up and running now and are catching up on work distribution.

The 1Gbit switch will be a substantial upgrade to our server room. The 10Gbit switch will become part of a very high speed SETI spectrometer to be deployed at the Greenbank Telescope.

Bug in server affecting older BOINC clients with NVIDIA GPUs.

Fri, 17 Aug 2012 05:37:11 GMT

We've identified a bug in the current BOINC server that is online at SETI@home. With older BOINC clients this bug results in running multiple SETI@home GPU applications simultaneously on a single GPU.

While we debug and fix the problem we've suspended distribution of NVIDIA work. We hope that everything will be back to normal some time tomorrow.

Recovering from power outage.

Thu, 16 Aug 2012 20:18:22 GMT

We're slowly recovering from the power outage. The main BOINC database was performing poorly at first for an unknown reason. We'll be monitoring it as the recovery continues.

New AstroPulse applications for GPUs.

Wed, 08 Aug 2012 02:08:58 GMT

We've released the first of four new AstroPulse Windows applications for ATI/AMD Graphics Processing Units that support the OpenCL language. If you've got an one of these GPUs you may be able to process AstroPulse results 15x faster than your CPU alone. If your computer supports a version, it should get it automatically.

The first release supports ATI GPUs on BOINC 7.0.25 or later. The second release (probably next tuesday) will support ATI GPUs on BOINC versions prior to 7.0.25.
The final two version will be for NVIDIA GPUs. (Until then NVIDIA GPUs will have to satisfy themselves with SETI@home results).

Thanks to the optimizers at KWSN and the folk at the beta project for helping me get this out.

Another Outage!

Mon, 11 Jun 2012 21:29:17 GMT

Our entire building suffered some wild power fluctuations early this morning, affecting many projects including SETI@home. This is completely unrelated to power issues from a couple weeks ago. Despite losing some hardware all of our services are recovering.

Major Power Outage at SSL

Fri, 18 May 2012 15:57:18 GMT

There was a major power outage on Tuesday evening that affected several buildings here on campus including the entire Space Sciences Laboratory. Power has been restored this morning, and we are slowly getting the project back on line.

Your chance to be internationally famous.

Thu, 05 Apr 2012 19:47:58 GMT

The author I mentioned in the previous news item would also like to interview someone outside of the US, hopefully in an interesting location. Again, contact me if you fit the bill.

Your chance to be famous.

Fri, 23 Mar 2012 05:13:35 GMT

We've been contacted by one of the authors of a book/multimedia project called "The Human Face of Big Data." They're looking to interview someone who is heavily involved in SETI@home (lots of computers) and is also participating in SETILive.

If that's you, drop me a line and I'll help you get connected.

SETI@home and SETILive

Thu, 15 Mar 2012 00:12:08 GMT

If you're wondering about the difference between SETI@home and SETILive, Dr. Korpela has posted the differences here.

Astropulse v6 has been released for linux and windows.

Tue, 13 Mar 2012 22:49:21 GMT

We've released the Astropulse version 6 application to the SETI@home project. The only real difference is a couple of minus signs in the code that were added to match changes to the way the data recorder works.

It'll take a while for the credit granted by this application to settle out to a reasonably constant value. If you run optimized applications, I'd suggest you wait a couple of weeks before starting to do Astropulse v6 work just to avoid the possibility that you will be granted an extremely low credit for your work.

Project Back Online After Overnight Outage

Tue, 14 Feb 2012 22:10:15 GMT

Update: After reaching a logical (i.e. not physical) limitation in our science database we had to rebuild one table. No data were lost. We resumed normal operations today around noon.

2 Billion Results

Tue, 08 Nov 2011 23:27:33 GMT

Tuesday morning we reached 2 Billion BOINC results processed by SETI@home! Or to be more accurate, 2 to the power of 31 results (2,147,483,648). This explains why we haven't yet recovered from the weekly outage: we need to update code to accept larger numbers.

BOINC download server is down.

Wed, 02 Nov 2011 03:49:57 GMT

The BOINC download server is offline, and will remain so for a day or two while we effect repairs.

Network routing problems have been fixed

Fri, 21 Oct 2011 17:50:51 GMT

For the last few months, network routing issues have been interfering with the connectivity of some participants. The actual problem turned out to be a lack of sufficient memory in our router at the PAIX in Palo Alto. Two days ago we increased the memory in that router by a factor of four. This fixed the problem.

We would like to thank Hurricane Electric, Packet Clearing House, and CENIC for their great technical help in diagnosing and fixing this problem.

Fall Funding Drive

Our annual fall funding drive has started. If you haven't gotten our message in your email, you can see it here. Please help us keep SETI@home going by donating today.

Another way to support SETI@home

Mon, 12 Sep 2011 20:38:21 GMT

In addition to crunching, you can provide some support to SETI@home by using GoodSearch and GoodShop. These search engines redirect a half their advertising to revenues to charity. Just be sure to choose "University of California - SETI@home" as your charity of choice.

more data on the way

Thu, 08 Sep 2011 16:56:49 GMT

In an attempt to push some older unanalyzed files through the pipeline we encountered data that could not be successfully preprocessed or split. This has resulted in work distribution going to near zero. We are currently transferring newer files from off site storage and soon will be receiving a disk shipment from Arecibo. Once these data are on hand work distribution will pick up.

storage service is back up

Sat, 28 May 2011 14:30:01 GMT

We have migrated storage service to thumper. Now it's a matter of transferring raw data to thumper, preprocessing it, and splitting it. This will all take some time. The Overland server is up and its raid is operational (thanks Overland!). Diagnosis of this unit is proceeding.

work generation temporarily halted (update)

Thu, 26 May 2011 16:03:55 GMT

The storage server has been repaired. It will take some hours to resync the RAID. We will let that process complete before restarting work generation.

Change of management at Arecibo.

Wed, 25 May 2011 17:50:14 GMT

ML1 pointed out an article about the change of management of the Arecibo Observatory. Cornell University, which has managed Arecibo since it opened, will no longer be managing the Observatory. A consortium of organizations will new be handling the management. We don't expect this to affect SETI@home much. It may mean changes to how observing is scheduled and how much observing time we receive per year.

Here's the press release for current GBT observations:

Mon, 16 May 2011 22:35:55 GMT

UC Berkeley SETI Survey Focuses on Kepler's Top Earth Like Planets

Green Bank Telescope observations to start Saturday.

Fri, 06 May 2011 22:29:54 GMT

Grad student Andrew Siemion reports that new modifications to a data recorder at Green Bank that we need for our Kepler SETI observations are now complete, thanks to a huge amount of help from Paul Demorest, a former grad student and one of initial authors of AstroPulse. Our first hour of test time is scheduled for this Saturday, 17:30 EDT. We'll be observing with 450 seconds per target on 90 Kepler field stars with interesting planet candidates (~habitable zone, ~Earth size, ~Earth period, ~several planets), then do a raster scan of the entire Kepler field.

Passing of a setizen.

Wed, 27 Apr 2011 22:07:36 GMT

We are sad to report that long time SETI@home volunteer Wes Wycoff has passed away. His efforts will be missed. Our condolences go out to his friends and family.

Allen Telescope Array Hibernation

Wed, 27 Apr 2011 21:44:03 GMT

As noted in the Scientific American and elsewhere, the Allen Telescope Array was recently forced into hibernation. While we are sad to see this happen, SETI@home receives its data elsewhere, so our project is not directly affected. Dr. Eric Korpela wrote a helpful Q&A about this in the SETI@home Staff Blog.

Microdonations through Flattr.

Wed, 29 Dec 2010 20:25:17 GMT

Thanks again for another year of generous support for our project! We couldn't do this without everybody's help. Onward to 2011...

Workunit Shortage

Mon, 13 Dec 2010 18:32:39 GMT

Over this past weekend we had an disk issue (unrelated to the new servers) which hampered workunit creation. We back to full production at this point, though due to high demand it might be a while until your clients receive new work.

SETI@home is back online

Wed, 08 Dec 2010 20:45:55 GMT

We've been offline for over a month to remodel our database servers. The bulk of this work is complete, and work is being distributed. Please note we may continue to bring servers up/down over the next few weeks (outside of regularly planned outages) as we wrap up the final stages of this major endeavor.

Donation Site Problems

Tue, 07 Dec 2010 23:13:40 GMT

Some browsers (especially older ones) may experience trouble with the SETI@home donation site at givetocal.berkeley.edu if the browser doesn't recognize COMODO CA, Ltd as a valid security certification authority. Details and a workaround are available here.

Dr. Masaki Morimoto, Japanese SETI pioneer, has died.

Tue, 16 Nov 2010 17:15:11 GMT

Dr. Masaki Morimoto, a SETI pioneer and one of the fathers of Japanese radio astronomy, passed away this morning at the age of 78. He suggested the frequency L11->L10 transition of formaldehyde (4.83GHz) as a possible magic frequency for extraterrestrial communications. He was active participant in SETI searches up to the present, and influenced many younger researchers. He will be missed.

The project is down while we remodel our database servers.

Thu, 28 Oct 2010 22:26:47 GMT

The machine that was running the main BOINC database has become too unreliable to use. The backup server does not have the capacity to run the project on its own.

The very good news is that we just ordered two new servers! One will be the new BOINC database server and the other will be the new back end science database server. Our capacity to both distribute and analyze our data will increase significantly with these new machines.

While we prepare for these new servers and get them going once they arrive, the project will be down. Although no new work will be distributed, all outstanding work will be uploaded and credited. This web site and the forums will remain up for most of the remodeling period.

Funding for the new servers has come entirely from very generous donations from the SETI@Home community.

Don Backer has passed away.

Tue, 27 Jul 2010 00:36:12 GMT

Don Backer, Berkeley professor and director of the Allen Telescope Array, passed away on Sunday, July 25th. Don was a very important contributor to radio astronomy and to the study of pulsars. He will be missed.

Arecibo Observatory Repair Status

Wed, 30 Jun 2010 20:35:17 GMT

Our science database server died on Tuesday, May 1st.
We haven't been able to create new workunits since then (though we are still
accepting completed results). Sun is graciously
replacing this server. The bad news is, despite earlier claims, it won't be
here until Friday the 11th, which means the earliest we'll be creating new
work is Monday the 14th. Thank you for your continued patience! Updates,
discussion, and more information about this and other server-related topics

the machine now and will be rushing it to us on Monday. Once we have
the machine up and the database recovered, we can start sending work out
again. Details on the server crash and our recovery from it can be found in Technical News.

Happy May Day

Tue, 01 May 2007 00:00:00 GMT

Happy May Day. Unfortunately for us it's been "Mayday! Mayday!" At 4:43 (PDT) this morning, our science database machine, thumper, became hasenfeffer. It currently refuses to acknowledge that it has any disk drives. Since the controllers are attached to the motherboard, major repairs will probably be required. No work can be created until this machine gets fixed. We are on the phone with Sun now in hopes of securing repair or a replacement. More info in Technical News.

Since the announcement of Gliese 581c
(the first possibly habitable extrasolar planet), we've been asked many times about

operations. At this point, the connection drop rate is
decreasing and should reach zero by the end of the day (PDT).

We have confirmed that there is a known network peering issue between Cogent
(our ISP) and OpenTransit (France Telcom) that is affecting connectivity for
many participants in Europe. Campus has opened a trouble ticket with Cogent
but we are unsure that this will result in a fix. We will post news items as
we learn more. Many thanks go to the posters in this message board thread for their diagnostics and work arounds.

The Einstein@home
project was officially launched this morning.
We encourage SETI@home users to also participate in this project,
which searches for spinning neutron stars (also called pulsars)
using data from the LIGO and GEO gravitational wave detectors.

Update

Fri, 18 Feb 2005 00:00:00 GMT

Update. Yet another data server array hang. The vendor is looking into it.

The project has been up for several hours although the data server
is a bit overwhelmed with pent up demand. We are adding services
back one at a time while we monitor the data server storage array.

Update

Thu, 17 Feb 2005 00:00:00 GMT

Update. Once the RAID rebuilds we are going to run a job to delete
old workunits and results from the array. These would normally be deleted
by the file deleter but the latter is still backed up from before the database
migration. The project will remain off through all of this.

The data server failed around 20:30 UTC for the third time in as many days.
The project will be down as we continue to diagnose the problem.

We will restart the database migration to the new hardware
Monday, February 7, at 18:00 UT. The outage will be several hours
long.
Currently, workunit production is falling behind demand. The
splitters themselves are able to keep up but are not able to insert
work fast enough because of competition for database access.

Wed, 08 Sep 2004 00:00:00 GMT

Yesterday we discovered that when result files are lost, say due
to a restore from a backup (restores involve both the DB and the ULDL
directories) the validator ends up in a endless loop. The entire result
set for an affected workunit gets ignored and after a while the validator
ends up enumerating only affected workunits and is thus in a loop. We
turned off the validator when we discovered this. Today we have coded
a fix and are testing it in the alpha project. While the validator is off
credits are not given but they should show up once we turn the validator
back on.

Some technical folks from Snap Appliance are on their way
to SSL to provide on site support. They will likely swap
out the CPUs.

The SnapApp folks were here for most of the afternoon

Fri, 03 Sep 2004 00:00:00 GMT

The SnapApp folks were here for most of the afternoon. They replaced
the processors with ones that are faster and have larger caches. More
importantly, we talked about how to stabilize the system. The plan is
to simplify both the HW and service mix as much as possible in the hopes
of removing the variable that is causing the hangs (and of course they will
be going for the root cause at their lab). We altered the startup
so that a bare minimal set of services are running. And we are going to
only use the 18000 head unit for now, keeping no data on the sd30 expansion.
This means moving some data around. We first have to move the upload/download
data to a temporary volume on the sd30, then reconfigure the space on the
18000 head, then move the uldl to the head. The move to the temp volume
is happening now. Tomorrow morning we will do the reconfiguration and
start final move. With luck we will have the project up by EOD tomorrow.

We have completed the SnapApp work around

Thu, 02 Sep 2004 00:00:00 GMT

We have completed the SnapApp work around. We had a bit of a scare
with a volume mounting issue but once again Snap App gave us great
support and all seems fine at this point.

The Snap App hung again

Thu, 02 Sep 2004 00:00:00 GMT

The Snap App hung again. We will be down for the night.

Wed, 01 Sep 2004 00:00:00 GMT

We will be having a short (less than 1 hour) data server
outage tomorrow at 16:30 UTC. We will be implementing the
Snap Applicance work around on the 18000.

Mon, 30 Aug 2004 00:00:00 GMT

We are back up after restarting the Snap Appliance and making sure
everything is OK. We had a long conference call with the engineers
at Snap this morning they have come up with a work around as well as
a potential fix that should end the system hangs. Thanks go to the
Snap App folks for working very hard on this problem.

During all of this some web site files were lost and these are being
restored now.

Sat, 28 Aug 2004 00:00:00 GMT

The migration plan has been rescheduled for tomorrow the 29th at 10am PDT. We
have brought down the scheduler and file upload handler until the migration
happens to give the splitters and transitioners time to produce enough workunits
and results to send out after the migration when the clients reset themselves.

We are currently experiencing a hardware issue with our scheduling server, we expect this issue to be resolved within the hour

Fri, 27 Aug 2004 00:00:00 GMT

We are currently experiencing a hardware issue with our scheduling server,
we expect this issue to be resolved within the hour. The upgrade to 4.x will
start around 11am PDT and will take roughly an hour. Anybody who has any
remaining results to report should get them in before the upgrade.
After the
upgrade you'll need the 4.x clients to report new results, and upgrading to
the 4.x client will reset the project on your machine. Roughly 100,000
results are queued up and ready to be sent out after the upgrade, plus the
three splitters will be up and running producing work as quickly as possible.

The last set of hardware issues have been resolved

Fri, 27 Aug 2004 00:00:00 GMT

The last set of hardware issues have been resolved. Due to the time of
day and other factors the upgrade will be delayed until at least tomorrow
morning. We'll post the revised schedule as soon as plans have been firmed up.

Thu, 26 Aug 2004 00:00:00 GMT

We fixed the bogus URL bug and all servers are back up. If your cache is
empty of all valid workunits and you have any of the bogus workunits, then
reset the project.

A clarification about last week's fallback to an earlier
DB state: all work that was uploaded during the period of
August 13th to 18th
was lost and so cannot be credited. As well, all work that
was generated and downloaded during that period was lost to the DB and so cannot
be credited. This work is being regenerated and redistributed.

Thu, 19 Aug 2004 00:00:00 GMT

The database has been restored and is being checked now. You may notice
that message board posts made in the past week are now missing - this is because
we had to fall back to an earlier copy of the database. Sorry for the
inconvenience.

All the data has been copied to the Snap device

Fri, 13 Aug 2004 00:00:00 GMT

All the data has been copied to the Snap device. Both attempts to
bring the project online met with an unexpected NFS issue. Roughly
ten minutes after bringing the project online the NFS daemon drops
the mount point. Hats off to the Snap technical support team who
have been helping us work through this issue. We are still
investigating this issue and don't expect to be back online until
the beginning of next week. In the meantime everyone have a great
weekend.

The DB is now on the Snap Appliance and the web site is back up.
The project itself is still down as the transfer of the upload and
download directories is still under way.

Thu, 12 Aug 2004 00:00:00 GMT

The download directory is fully transferred at this point, but we
are still waiting for the upload directory to finish. We predict
it will finish late in the evening, and we'll start the project
fresh tomorrow morning.

The project is now down for the move of the DB and the upload directory to the Snap Appliance

Wed, 11 Aug 2004 00:00:00 GMT

The project is now down for the move of the DB and the upload
directory to the Snap Appliance. Along with the still running
download move, this will be a long process. We hope to be back
up midday tomorrow.

We have started the copy of the download directory to the Snap Appliance 18000.

Tue, 10 Aug 2004 00:00:00 GMT

We have started the copy of the download directory to the Snap

The servers are back up as far as receiving results but not as far as distributing new workunits

Sun, 08 Aug 2004 00:00:00 GMT

The servers are back up as far as receiving results but not as
far as distributing new workunits. We are simultaneously clearing
out the old download directory and preparing to move both it and the
upload directory to the Snap Appliance, along with the DB.

Allowing result uploads will ultimately speed both the deletion
of old workunits and results and the granting of credit. Credit
for the backlog of results will start being granted once we move
to the Snap Appliance and turn on the hierarchical directory structure.

Sat, 07 Aug 2004 00:00:00 GMT

The scheduling server is down while we work on a download storage
problem. This may take a day or so.

Fri, 06 Aug 2004 00:00:00 GMT

We developed a hierarchical directory structure to get around the
big directory problem (see August 4, below). This solution is backward
compatible with all current work units. It is being tested
in alpha now. Next week it will go to beta and then to public.
We also have a tool to distribute all recent results into the
new hierarchy. When that tool is run, credit will appear for
all of these results. The credit appearance will be spread over
a number of days.
In other news, we have the SnapAppliance 18000 configured. It
shows a 10x speed up over the software RAID we are now using. We
are awaiting a UPS for it.

We discovered that the sheer number of files in the upload directory was killing NFS performance for the file_upload_handler

Wed, 04 Aug 2004 00:00:00 GMT

We discovered that the sheer number of files in the upload directory
was killing NFS performance for the file_upload_handler. We started
with a new empty upload directory and the file_upload_handler performed
much better. The rate of connection drops on the upload server dropped
to zero (most of the time). Of course we need to get all those older
results back into play somehow.
We are preparing our new SnapAppliance 18000 to host the database. We
need to fit it into the power load in our already fairly full data
closet, configure the DB volume, run some tests, and then copy over
the DB files. We will post the progress as we go.

While the project is up and functioning normally, the database and
web servers are overloaded. Because of this you may have noticed
difficulty in transferring work and loading certain web pages.
We're tuning these servers and trying to find the bottlenecks now.

Mon, 02 Aug 2004 00:00:00 GMT

The project remained down all weekend, but we are back up now.
To add insult to injury, the entire lab lost network connectivity
to the rest of the world for a few hours this morning.
In light of the unexpected length of this last outage, we are looking
into mechanisms that allow us to keep certain parts of the
project up while others remain down for repair.

The project is still down

Fri, 30 Jul 2004 00:00:00 GMT

The project is *still* down. The database cleanup for the bug
found on July 28 is going much slower than expected. We hope to
have everything back up later today or early tomorrow. Sorry for
the inconvenience!

The project is currently down

Wed, 28 Jul 2004 00:00:00 GMT

The project is currently down. We found a bug in the scheduling
code such that returned results were not being updated in the
database. We are now running a fix script on the DB, marking
each affected result as unsent so that it will be resent.
Unfortunately, credit was not given for results affected by the
bug.

The project is down while we deal with a backup problem

Sun, 25 Jul 2004 00:00:00 GMT

The project is down while we deal with a backup problem. We hope to be
back up soon.

We have shutdown the schedulers and file upload handlers so the transitioners can play catch up again

Sun, 25 Jul 2004 00:00:00 GMT

We have shutdown the schedulers and file upload handlers so the transitioners
can play catch up again. The transitioners keep falling behind because the DB
is I/O bound. We believe that the new hardware we have coming online will
resolve this issue. Until it is online we'll be continuing these rolling
blackout style server outages.

We are now up and running again, during the night we generated 400k results to be sent out

Fri, 23 Jul 2004 00:00:00 GMT

We are now up and running again, during the night we generated 400k
results to be sent out. Things might be a bit weird for awhile, somebody
decided to launch a denial of service attack yesterday afternoon.

The good news is that the scheduler is now running as a fast cgi which means it maintains a persistent connection to the DB

Fri, 23 Jul 2004 00:00:00 GMT

The good news is that the scheduler is now running as a fast cgi
which means it maintains a persistent connection to the DB. The
load on the scheduling server has gone way down which is a good
thing and the mysql server is using more CPU which is also a good
thing. The bad news is that the transitioner is still way behind
and so the project will probably run out of send-able work as
early as 04:00 UT tomorrow. The transitioner is slow because the
mysql server is IO bound. We are having Sun look at our IO system
to see if it can be tuned to better performance. At the same time
we are planning on moving the physical DB to a high performance Snap
Appliance box in the near future. So we are hopeful that these IO
problems can be solved.

Yesterday we introduced a bunch of performance enhancements to the system

Thu, 22 Jul 2004 00:00:00 GMT

Yesterday we introduced a bunch of performance enhancements to the
system. During the course of letting the system run overnight, we have
detected a bug that keeps results from being sent to hosts. It looks
at though this bug has only been around for about 13 hours. While we
are debugging this issue we have decided to shutdown the scheduler
and try and let the transitioners pick up the pace a bit.

We found and fixed the no results bug

Thu, 22 Jul 2004 00:00:00 GMT

We found and fixed the no results bug. It was a malformed
embedded SQL query. But we are leaving the scheduler off
overnight to let the transitioner work through it's backlog.
The transitioner works a great deal faster with a small
backlog and we hope yesterday's changes will go a long
way in preventing a large backlog from recurring.

The log files are currently being compressed, after thats done the project should return to normal.

Mon, 19 Jul 2004 00:00:00 GMT

We have brought up an additional transitioner to try and cut through
the backlog we have accrued. Since the beginning of the project we have
already processed 2.7 million results. For comparison, the beta project
had only processed 6 million through the whole life of that project to date.

A server bug was preventing
new results from being created in response to failed results.
If 2 out of 3 results for a WU succeeded and the 3rd failed,
the 2 successful results would not be validated or credited.
This is now fixed and the system will issue new results for
all workunits in this state.

Thu, 08 Jul 2004 00:00:00 GMT

We have moved the scheduling server to another machine in
order to free up CPU and memory for the DB server. Active
clients will fail 10 times to connect to the old scheduling
server and then will self correct by contacting the master URL.
To force the correction right away, simply detach and then
(re)attach the project.

Since yesterday evening we have distributed over 600,000 results

Thu, 08 Jul 2004 00:00:00 GMT

Since yesterday evening we have distributed over
600,000 results. Thats a six-fold increase in
overall system performance from our previous best. Now it looks
as though we'll have occasional workunit shortages as we'll
have to bring additional splitters online to keep up with demand.
It's 8:50pm PDT and we have about 30,000 results in the queue, and we
are sending about 1,000 every 10 minutes. Currently
the splitters generate 4 workunits per minute which creates 12 results
per minute.

Wed, 30 Jun 2004 00:00:00 GMT

Yesterday morning we shut down the front end of the system
to let the transitioners catch up with several days worth
of backlogged work, which is why some of you were noticing
three results and no credit assignment. During the down
time we also converted the scheduler into a fast-CGI
application. Upon bringing the system back up the new
fast-CGI scheduler decided to choke on something that it
hadn't choked on in Alpha. We are currently debugging the
new scheduler. We were able to get through 60% of the
backlogged work.
