Alas ... that's a bit depressing.

I'm into SETI@home since 17 Oct 2002, and all my PCs ever since had constant full load whenever running. That accumulated 9,910,636 credits up to this very moment (SETI@home only ! More to find on other projects ...). BTW: BOINC was even on my smartphones, crunching all thru the nights while charging ...

Probably worn out 2 NVIDIA GTX 570's on it, and finally got a RTX 2808 super in order to wield a really big alien searchlight ...

I hope the follow up analysis would show up many a things interesting.

And I hope the final weeks would get me the chance to pass the 10 million credit milestone ;-)

Let them astronomers find new tasks for SETI@home ... I'd let the project connected and stay tuned. And I hope the final paper(s) would be open access (I'd rate any paywall in front of the results as real annoyance, pals). Maybe there's more SETI search in the future, which could utilize the infrastructure, too ?

So have a nice rest, SETI@home ...

PER ASPERA AD ETI !

Thanks ... I suspected something like that (similar problem with my old GTX570 <rest in peace, old workhorse ...>).

Reverted back to 431.60 (with some potholes underways ...) and now it runs better ... let's wait what my RAC says after some days.

GPUTemp reports "GPU Core Load" between 80 and 99% most of the time, "GPU Core Temp" at about 45°C (custom fan profile ...)

Hi friends,

my good old GTX570 unfortunately passed away <sniff> so I got something to lighten up my sad heart ... a nice MSI RTX 2080 Super.

Unfortunately it looks like BOINC/SETI@HOME is not stressing it in any way ... :


GPUTemp tells a GPU temperature of 38 °C, and the core load it 1% most of the time, jumping to 50% every now and then for a moment.

Environment: Win10x64 (1903), 32GB RAM (16 GB as RAMDisk), plenty of HDD space.
NVIDIA driver 441.66.
Mainboard: Gigabyte GA-Z86X-UD7-B3

Any hint how to fix that ?

Hi there,

i'm running SETi@HOME on my Google Pixel 2 XL phone whenever it's at the charging ... not very much calculating power, but every little bit helps ;-)

Now I've just updated to Android 10, and it looks like BOINC/SETI is broken now. Each workunit tells me "calculation error" with exactly ZERO work done on it, and BOINC tells me that it's doin' nothing and it's waiting for new work.

Terminating the workunits results in nothing at all.

Any hint ?

Thanks in advance

8) Message boards : Number crunching : Problems with NVIDIA Fermi / SETI@HOME / Win10 Update to V1803 ? See here (Message 1937079)
Posted 25 May 2018 by Profile Seneca Special Project $75 donor
Post:
Hi friends,

just for your convenience if you run into the truoble I experienced:

After updating my Win10 pro desktop machine, containing a NVIDIA GForce GTX570 (based on the Fermi architecture), I faced severe problems, probably due to a NVIDIA driver in the update (388.x).


  • Initial symptom was SETI@HOME not recognizing the GPU, therefore not crunching anything with it.
  • Subsequently I had problems with the driver (any version) refusing to update/reinstall.
  • After solving that mess, the GPU was detected, but ran with the handbrake fastened at about 10% speed ... a regular SETI@HOME workunit ran more than 3 hours instead of the usual about 10 minutes (or about 1 hour on a single i7-2600k core).



Final remediation was


  • Run DDU (get the newest release, but at least V17.0.7.5) in Windows Safe Mode
  • Reboot
  • Run
    sfc /scannow
    DISM /Online /Cleanup-Image /RestoreHealth
    as administrator
  • install NVIDIA driver 375.70 (anything more recent I've tried failed ....)
  • probably reinstall BOINC (not sure if needed)

Ich denke mittlerweile, das sollte so ganz OK sein ... die Temperatur geht bis max. 72°C hoch und ist i.d.R. so um die 65°C.

Die Lüftersteuerung steht auf "Auto" - gerade habe ich 70°C, Core 99% und der Lüfter dreht bei (automatischen) 60%

Ach ja - ein Wert fehlt noch: Die Video Engine steht i.d.R. bei 0%, was insgesamt die Auslastungsanzeige erklären könnte.

By the way: Meine CPU köchelt derweil bei dezenten 78°C vor sich hin ... da sind maximal 98°C zulässig, und ich denke konstant knapp 80 sind CPU-freundlicher als ständiges auf und ab ...

In welchen ?

Vielleicht hat sich die Frage auch irgendwie erledigt ... das Programm GPUTemp zeigt

    GPU Core Temp 69°C
    GPU Core Load 98%
    GPU Memory Controller 45% ... 78%
    GPU Memory 50%



an ... das sieht eher korrekt aus ...

Post:
Just curious ...

I'm running BOINC with mainly S@H on a Windows 10 machine with 32GB RAM and a NVIDIA GTX570 GPU in a PCIe x 16 slot.

While inspecting the GPU usage with Sysinternals ProcessMonitor, the display in the GPU engine history (System Information -> GPU -> Engines) I get 16 engines displayed, but there are not more than 4 of them used ... the others remain a zero percent load ...

Of the active engines only one or two are working at about full load, the others are only spiky with approx 30% averaged load at max. GPU temp is reported with around 65-70°C by RealTemp.

Is there any misconfiguration, or is it expected that the GPU doesn't look to be working at full load ?

Curious greetings

Posted 20 Aug 2013 by Profile Seneca Special Project $75 donor
Post:
OK - I've failed to read back that far ... sorry for asking about sth already discussed that much.

I've got the clue - for some design reason the RAC values drop by 50%.

I'll watch the behaviour if it comes up again, but I presume that will not be soon.

I'm somewhat puzzled about the RAC calculation ... I would presume that a workunit consumes an amount of calculations, which converts to credits somehow (credits = operations x factor). Looks like that's not the truth ?

Is there any doc how Credits (and RAC) is calculated ?

With my actual machine, I got RAC scores of 4000 and (slightly) above if rumming about 8 hours a day. Since seti@home 7 I see no more than about 2800.

Any hint ?

Post:
OK - that's an explanation - thanks. Maybe such condition is worth a news entry ?

My PC won't get idle, too - it runs Einstein work instead, and Rosetta as 3rd choice.

Currently Einstein steals away even GPU capacity with "high priority" workunits ... maybe that helps to return SETI to normal behaviour.

Post:
Hi friends,

I have a problem with my seti@home client ...

For some days now, BIONC doesn't fetch an more CPU work packets - or to be precise, it requests the but doesn't get any. The communication seems to be OK, because I constantly get fed with cuda_fermi work.

Is there a shortage in CPU workunits ?

Post:
Rosetta is CPU only, Einstein is both. What are the resource shares of your projects?


SETI 1000
Einstein 0
rosetta 1e-7 (doesn't accept zero)



Probably a mixture of resource share, cache settings and coming up empty when asking SETI.


If I explicit stop Einstein & Rosetta, I get SETI CPU work, and it stays on until done - along with the always running CUDA work - even when E&R are re-enabled again.


When coming from 6.x BOINC swap your cache settings around.


Where & What ?


Regarding the errors - -177 from CPU fallback due to CUDA card disappearing - Update your NVidia driver to 300.x or downgrade to 290.x


Went back to 285.xx - runs smooth.

Needs some more watchful waiting, but I'm full of hope =;-)

Anyhow - SETI is still delivering almost only CUDA work to me, resulting in crunching Einstein and rosetta packets, which are fallback projects for me ... any hint on that ?

It might help if you unhide your computers so folks could have a look at your results and see what the errors are.


Done. ID 6188051. Hope it helps ...

But avoid driver versions 295.73 and 296.10, which are known to have a bug.


Just running 296.10 ... I'll try rolling back to 285.62.
