Running 2 beta 6.08 WUs at the same time on a GTX295 takes longer than they would if you processed them with 6.71.
You get the same result if you are fully loaded with 8 other CPU WUs or if you reduce to 7.

Thanks - Steve

Could somebody with one of those failing GTX260 see if the beta app works for them?

Just started running one IBUCH task using the 6.08 Beta application on a GTX260 sp216:
No problems after 53minutes, just over 15% complete. Task says it is using 33%CPU.
From resource monitor I can see that the GPUGrid task is using about 7% of the total CPU (Phenom II 940). It fluctuates from about 3% to 11%, but mostly sits around 7%, which is 28% of one core and close enough to stated 33% (more accurate than my ability to read a percentage line bouncing up and down).

Was this GTX260 causing problems for the FFT bug before?

Picked up 4 IBUCH_1000smd on my machine with dual GTX260's (65nm). Current estimate is 3 hours 40 minutes to completion. Will let you know in a few hours how they go. Link to host here.

No. The FFT bug is not a problem on my 55nm GTX 260, as it uses the G200b revision. The problem was seen on the earlier 65nm G200 versions of the GTX260 – both the 216sp and 192sp card versions. I no longer have one of these versions.

Still, the 55nm card can act as a comparison reference.

MarkJ has an earlier 65nm (G200) GTX260 card, which would have been subject to intermittent FFT errors, and is running a Beta.

Siegfried Niklas, Which version is your card?
- GTX 260 sp216 55nm, GTX 260 sp216 65nm, or GTX 260 sp192 65nm?

For reference,
my 144-IBUCH_1000smd_pYEEI_100202-0-10-RND5155_1 task completed in 5h 34min. http://www.gpugrid.net/result.php?resultid=1810596
Completed and validated:
Run Time 20,202.83
CPU Time 5,240.67
(Credit claimed 3,977.21, Credit granted 5,369.23)

- My GTX 260 (G200b) 216shaders:
GPU 625MHz, Memory 1100MHz (X2), Shaders 1348MHz (Factory Clocked)

- The NVidia Reference clock rates for the GTX 260 cards:
GPU 576MHz, Memory 1998MHz, Shaders 1242MHz.
Most cards are somewhat factory, if not user, overclocked compared to these.

As the GTX 280 also uses the 65nm G200 core technology, it too was presumably subject to the FFT bug.

It is a GTX 260 sp216 55nm Rev. B1

I run a GTX 260 sp216 65nm Rev. A2 on a other host (same OC). No significant difference at "process priority: below normal"

(I had only one "TONI_TEST -ACEMD beta version v6.08" on the "65nm Rev. A2" card.
I never had problems with the "FFT bug")

sorry, to ask this stupid question:
I just would like to ask for support how to add my system to run the test applications? I enabled 'Run test applications?' in my GPUGRID preferences but this seemed to have no effect. Is there anything else to do?

system is an ubuntu 9.10 64bit with 2 x EVGA GTX275 FTW

Best regards,
dsred

dsred, you have done all you have to do.
You could watch for Beta releases and abort any queued GPUGrid tasks to force a task request. You would however need to be watching the forums closely otherwise you would get a normal task, in which case you would have wasted your time, and the GPUGrid server’s time. If you are going to do things like that it is more beneficial if you chip in by posting up your beta result details.

1st wu (RND8704_2) is on 89% and thinks another 40 mins to complete

2nd wu (RND4096_1) stuck at 7.12%. Suspend/resume in BOINC seems to have got it going again and its now up to 9%.

3rd and 4th wu waiting to run.

Host is also running 8 Einstein GW searches on the cpu, so that might have slowed things down a bit.

It is just for windows now.

Does anyone know if running a gtx295 as one card
instead of 2 x gtx200's has any efect on process time?

1st wu completed successfully. Link to wu here

2nd wu failed. Had 2 popup windows on the console saying app has stopped responding (seems to be new with Win 7). Link to wu here

3rd and 4th wu now running.

Cards are GTX260 (65nm) 216sp revision A2

I'm afraid the GeForce 9600M GT (laptop) is not suitable for the project... thanks anyway.

Hi.. thx for information.

But i'd crunched several WU's til yet (switching to Beta) with the normal Cuda-App.?!


best RS

you can still run another gpu project like folding@home

according to the chart the gpu is supported, just slow... strange

hm... i understand..

...but i HAD crunched here at GPUgrid with THIS GPU!
Would my card at this moment not further supported at all? Or only with the new beta-App?

(Sorry for poor english)

Your card IS supported -- but is considered too slow to reliably return WUs quickly enough to make the WU deadline.

That speed determination is a generalization. Since you have your computers hidden, I can't determine how long it was actually taking your computer to crunch the WUs.

If you have been crunching WUs already (and returning them within the deadlines) then you'll continue to be able to do so. Since the new application is faster, it will be somewhat easier for slower cards to meet the deadline -- assuming the GPUGRID folks don't either increase the amount of work done in each WU and/or lower the deadlines as a result of the faster algorithm.

If you're missing the deadline, you're A) slowing down the project (bad for the science) and B) possibly not getting credit for the WU (bad, if that's important to you.)
