Has anyone seen any good deals on dual LGA2011 motherboards recently for the Xeons E5-2670/E5-2660's? The CPUs are still going for very little, but the MBs seem to be a really hard thing to come by.
With my recent change in job and increase in finds I was hoping to put something along these lines together for my home VMware box.

AMD rumoured to be revising Polaris

    »  "They should be out under RX 4XX branding in a few months . . ."

I was just thinking of replacing the old HD6870 in my HTPC with a RX 460, but maybe I'll hold off for a bit now.

From my understanding, WSUS still gets the individual updates, as well as the rolled-up one. But truth be told... I turned Updates off on both of my machines.

I don't really see a point in continuing to get these updates, unless you still use IE and go to sketchy websites frequently. For those of us who excise a bit of caution and sense, we can basically run without updates or even A/V without issues--I know I did just that for a number of years back in the XP days, even with IE6. Someone called BS on the fact that I was using IE6 and had no A/V and claimed I had no infections, so I downloaded the A/V scanner they considered the best and ran a full system scan... it came up clean.

A little bit of caution goes a long way.

I haven't used AV software on my main home rig since the 90's. All I ever found AV good for is slowing down a perfectly good system and quarantining needed files from false positives.

I seem to recall that error would occur when BOINC was run from an SD Card, but I don't believe that any version of BOINC supports being installed that way.
6) Message boards : News : Replica database offline... (Message 1823886)
Posted 9 days ago by Profile HAL9000
Perhaps there could be a project for an intern to make an automated forum/BOINC notice system that would post a message along the lines of "___ has unexpectedly gone offline. Staff has been notified. Please be patient while the issue is resolved."

The "problem" is the notification is (usually) an email, which the puts the next step onto the "intern"/staff to read the email - even on vacation, or when out sick.

The reason I mentioned an automated message that posted to the forum or used the BOINC notification system. I think all news posts get routed to the notification system anyway.
Since there are always those that whine and throw a fit about "no one tells us what is going on or acknowledges the problem". While forgetting about all of the times the guys have stayed up late, taken time out of their weekends, or holidays to fix issues.
It seems like something that might improve PR a bit.

There is a message on the front page

Replica database offline...
The replica database will be offline until we can restore it from the primary database on tuesday (at the earlies). This will result in slowness of the web site and the scheduler.

Indeed. I hope Eric was actually feeling better & not just pressured to give us some info.

Hence my earlier question:

"Is Eric the only one who can add a message?"

If he is then surely that needs changing. Simple contingency planning.

If he isn't then why didn't anyone else take 30 seconds to give the update several days ago?

BTW Eric's note is exactly what was needed and I'm grateful for it.

Jeff & DA can. However there schedules may prevent them from being able to do so.

I did just see a small increase in total credit, so I'm prepared to believe that there is simply a huge backlog. Still there should be communication when something like this happens. How long does it take to type, "Sorry for the delay in crediting results. There was a problem with X. Things should be caught up by Y. Thanks for your patience and contribution to the project."? Actually that should be done using the Notices facility, so people don't have to come here to find out what the hell is going on.

Since it is still the weekend there should be no expectations for any type of communication from the staff. With Eric out of commission there might be two other individuals on the Berkeley campus that would be able to monitor the system and report any information to us. However they may not even have the time to go "up the hill" to the Space Sciences Laboratory to check on things. With all of the other backend running in good order it really is a very minor problem.

Checking the Free-DC stats for your account it shows you were at 1,579,852 as of the 2016-10-05 stats dump and at the time of posting this you are at 1,616,918. A difference of 37066. It looks like you normally gain 8,000 to 10,000 credit a day. So the numbers look pretty spot on from my perspective for the past 4 days. I would say everything else but the display of host and task info seems to be working.

Over there years there have been issues of much greater magnitude. Sometimes we were informed of what had happened.

I have exactly the same problem, and as usual nothing from the lab to explain why or any sort of time scales for putting it right.

It is not the end of the world but damn irritating to the faithful followers.

Matt always used to give a weekly tech update, those days are long gone and so it seems is Matt. Eric is far too busy, and Jeff has other stuff to do. As I understand it there is nobody else.

Users 1,650,412
Active users 138,387 (8.38%)
Hosts 4,063,801
Active hosts 160,861 (3.96%)

Those numbers could fall even further if this doesn't get sorted out. If there is something seriously wrong with Caroline then why not say so? If they need funding to replace or upgrade it I'll chip in what I can. We can't help if we're kept in the dark.

My 16th Seti Anni is due in 10 days and I'm not going anywhere, but a bit of feedback wouldn't go amiss?

It is good that Matt is at work for breakthrough listen these days, but sadly that left SET@home with fewer day to day resources.

I'm not having any issues returning and getting new work. Sometimes in the past if they new the replica would be offline for a long time they would switch over to the live data on the master for us. Since that didn't happen I would guess that perhaps they started a rebuild or restore on the replica and left it to run over the weekend. Then perhaps Monday or after Tuesday maintenance it will be back online.

Posted 12 days ago by Profile HAL9000
BOINC tries to allocate resources to projects as best it can but sometimes I feel it needs a bit of help. One method that can be employed is using an app_config.xml to limit the number of takes a project runs at once.

You could using a simple app_config for asteroids like this. Which would always leave one free thread open on your CPU to run SET@home.
<app_config> <project_max_concurrent>3</project_max_concurrent> </app_config>

The downside to this method is that if your systems had 0 SETI@home tasks it would still only run 3 asteroids tasks.

come on replica! Breathe! (Need data for some code polishing :D)

Would be nice if someone in Berkeley at least let us know if they're working on it and/or what the issue might be. Then again, communicating useful information to the great unwashed masses is not their strong suit.

With Eric ill plus the longstanding manpower shortage it is quite understandable.
I really, really miss the replica.

Is Eric the only one who can add a message?
Has nobody had even 30 seconds during the last several days to at least acknowledge the issue?
Maybe they've found ET, decided they're not helpful, job done, shut down commenced, all gone home!

For a project so reliant on 'us' it sometimes appears that we are not deemed very important.

Well there is no full time SETI@home staff. They all have several other responsibilities to work on & may only allocate a few hours a week to work SETI@home stuff. They could spend that time working on the issue or telling us something is broken with an unknown time to fix. Which will have users posing more questions.
Also the replica database server isn't required to run the project. If it goes wonky for a while it isn't a problem. It does make it more difficult is users needing help troubleshooting any issues.

Posted 16 days ago by Profile HAL9000
I imagine that the project will continue to support OS X PPC for as long it is possible to compile an app for it.
I'm not sure if they are already to the point of the PPC app being provide by a volunteer rather than compiled in house.

It is called creditnew.

And also each project can set however much credit they want to for work. Some projects give large amounts of credit to attract more participants.

And don't we also have to consider the threshhold calculation when considering whether the outcome of those averaging/blocksum calculations is reportable?

Yes. For the fixed thresholds such as spikes there is an issue whereby a spike happening to fall just above threshold will be reported, and in another system may not. That uncertainty is the 'threshold problem' Eric has alluded to in the past, whereby there is no hysterisis band on reportability. [I have offered forward suggestions for solutions for the future, and Eric has expressed interest, though they require detailed modelling, and integration of error measurements in the apps (partially present in stock CPU bench part)]. Unlikely to go in anytime soon since v8 was pushed out before these moves could germinate fully.

For the changing thresholds that are calculated, similar constraints apply for the levels or fit, with the complication that there will be some small amount of unavoidable error in the threshold value calculation itself.

[Edit:] I should point out that we're talking tiny fractions of very small numbers, that, where would apply, would stand out as being close to some threshold in one or another result file)

Interestingly techniques for this sortof stuff were invented at Berkeley decades ago, but mostly ignored in the US. The Japanese took up a lot of the work in that area and made autofocus, and ricecookers into things.

It's good to know that the maths behind looking for ETI signals & perfectly cooked rice are related.

Also at the rate that processors are being stuffed into everything I expect my next rice cooker will be able to run some of the SETI@home apps in a timely manor.

Posted 22 Sep 2016 by Profile HAL9000
I must not have been as specific as I intended.

My plan is to download SETI@Home from the BOINC site; not to download BOINC again.

I understand that SETI files come from SETI.

No, now that I re-read my original question, I was more than specific enough in describing what I would like to do. The problem seems to be that you had difficulties understanding my description.

In looking at the S@H files in the projects subdirectory, it looks like I'm missing some files. My plan is/was to finish up all my current S@H tasks, completely unload S@H, reboot everything and reinstall S@H from the BOINC site on the assumption that I will get a complete fileset.

The main reason your machines are not getting Astropulse work is because the project has been issuing very little of it.

There isn't really any "install" for the SETI@home project files. Unless you are referring the using the Lunatics optimized application installer.

If you feel your local project files are damaged in some way you can simply hit the "Reset Project" button in BOINC. Then the application files will be downloaded as needed when your machine is issued new work.
19) Message boards : Number crunching : RX 480 - A serious contender? (Message 1818564)
Posted 21 Sep 2016 by Profile HAL9000
Actually the RX480 is in my graphs under "Ellesmere" -- it's infuriating but it seems like the CUDA device identifier insists on naming the family not the model which tragically will mean this includes RX470's etc -- however if you go back in that thread you'll find my earliest data for Ellesmere was consistently mediocre even with the RX480 was the only part in circulation.

BOINC 7.6.23+ uses a new name detection method for Radeon GPUs so that the BOINC developers don't have to hard code the GPU names. I don't know if you are taking that into account when searching for GPUs to chart.

This is how my R9 390X is displayed with the new code vs the old.
BOINC 7.6.23+: AMD AMD Radeon (TM) R9 390 Series (8192MB) OpenCL: 2.0
BOINC 7.6.22: AMD Grenada (8192MB) OpenCL: 2.0

For clarity I should have stated that the new detection method is only for non-CAL GPU/drivers. Older drivers that still report a CAL version will continue to display the hard coded names from BOINC like:
AMD AMD Radeon HD 7870/7950/7970/R9 280/R9 280X series (Tahiti) (3072MB) driver: 1.4.1848 OpenCL: 1.2

Also it has been found, at least in Linux, that no board name is displayed for RX 400 GPUs. Do we have any Windows users with a RX 400's using a BOINC 7.6.23 or newer?

There's a suitable power plug or two. I just ordered a multimeter.

Will be very interesting to see how the 5/12v moves when BOINC is and is not running... can't say I've tested that, either ...

If you really want to see something scary you should use an oscilloscope to view your power rails at idle & with BOINC running apps.
I did that a few years ago on one of my machines.
