NRAO telescopes will be taken offline due to government shutdown
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. 3 Oct 2013, 17:11:45 UTC · Comment
We are now mostly recovered from a campus wide power outage.
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. 1 Oct 2013, 21:48:07 UTC · Comment

AVG 2013 virus scanner false positive on SETI@home 7 for Windows
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. 30 May 2013, 17:45:58 UTC · Comment
SETI@home Version 7 has been released
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.

Continued server problems.
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. 19 Nov 2012, 1:02:54 UTC · Comment

New AstroPulse applications for GPUs.
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).

Astropulse v6 has been released for linux and windows.
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. 13 Mar 2012, 22:49:21 UTC · Comment

The project is down while we remodel our database servers.
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.

We are currently managing several problems with the science database server. The database will be okay, but it is currently offline. It was take a while before we are fully back up and running normally. In the meantime we will mostly be unable to create new workunits, so expect your clients to run idle for the next few days (unless you are running other BOINC projects!).

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

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.

For the first time in a very long time the validator has caught up
on the large backlog of results waiting for credit. Of course, many
results still have pending credit until similar results are returned

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

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. 3 Sep 2004, 0:00:00 UTC · Comment

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. 28 Aug 2004, 0:00:00 UTC · Comment
The last set of hardware issues have been resolved. Due to the time of

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.
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. 27 Aug 2004, 0:00:00 UTC · Comment

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. 8 Aug 2004, 0:00:00 UTC · Comment

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.

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. 4 Aug 2004, 0:00:00 UTC · Comment

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. 28 Jul 2004, 0:00:00 UTC · Comment
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. 25 Jul 2004, 0:00:00 UTC · Comment
The project is down while we deal with a backup problem. We hope to be
back up soon. 25 Jul 2004, 0:00:00 UTC · Comment
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. 23 Jul 2004, 0:00:00 UTC · Comment

We found and fixed the no results bug. It was a malformed

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

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. 8 Jul 2004, 0:00:00 UTC · Comment
We have moved the scheduling server to another machine in
order to free up CPU and memory for the DB server. Active

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. 30 Jun 2004, 0:00:00 UTC · Comment
