Jim, I think that is a fair assessment.
This issue is most likely caused by the WU running on the app in a slightly different way than the other WU's. It's been around for some time, but difficult to spot due to other errors (especially in the summer months). I have mainly just been running the Beta WU's (for half the normal Long WU credits), and recently only came across this issue the once on a Linux system.

If it's just being caused by Noelia WU's then we need a mechanism to allow crunchers to select to not run these WU; either put the Noelia's in the Beta queue or create another queue. It doesn't appear to be effecting some systems, and the Noelia WU's pay the best, so others will want to run these WU's.

If nothing will fix this, I will delete GPUGRID and run another BOINC program.

Paul,
Looking at your tasks' stderr.out file, they are full of:

# BOINC suspending at user request (thread suspend)
# BOINC resuming at user request (thread suspend)

which means that your BOINC manager keeps on suspending and resuming the GPUGrid application. This could be the result of improper settings of the BOINC manager and/or Windows.
For example:
1. The CPU project you are running uses too much CPU time
resolution: you should limit the CPU usage of those projects to give the GPU projects a single core per GPU by the "on multiprocessor systems use at most" 50% of the processor cores (as you have a dual core CPU, so 1 CPU core is 50% on your system) in the Boinc Manager (Advanced View) / Tools / Computing preferences / processor usage tab
2. The BOINC manager "throttles" its applications
This setting is used to limit the heat generated by the CPU, but it throttles the GPU applications also by mistake.
resolution: go to Boinc Manager (Advanced View) / Tools / Computing preferences / processor usage tab / use at most 100% cpu time
3. The BOINC manager is not using the GPU while you are using your computer
resoluntion: go to Boinc Manager (Advanced View) / Tools / Computing preferences / processor usage tab / check the "While the computer is in use" and the "Use GPU while the computer is in use" checkboxes
If you play games which needs the GPU, you should put them on the list in the "Exclusive Applications" tab
4. Windows power management limits the time while your computer is "awake"
resolution: go to Start / Control Panel (large icon view) / Power options / change current scheme settings / Put the computer to sleep: Never

On my 660 two times today the GPU clock was down clocked. The WU's where beta ans Santi. My 660 has the most problems with Santi and almost none with Noelia's.
I regret that I have bought two 660's during summer, as my 770 is running fine with all WU's and very little errors. The card was more expensive but absolutely no frustration to run, while the 660 is frustrating me several times a day. The will be replaced by 7xx before the year is over.

Greetings from TJ

I have deleted gpugrid from my computer.

I suspended all runs except for the gpu

It runs but the remaining times keeps increasing. never more never more.

Will try 50% processor and 100% CPU.

Will let you know how this works.

Had my first GPU completion in quite awhile after the CPU & processor usage change ... Thanks !

Sooo whats the official solution for this, because this problem seems to still remain on short queue here on a 560ti 448 core edition. Lucky i can switch to long runs only with this card, but want to set it for both queues any later again for dont lose any publicationbadges ;) restart the machine after every short unit on an unattended machine is no solution ;)

What drivers are you using? It looks like your computer is using 301.42 from May 2012.

I'd recommend trying the most-recent 331.58 drivers that were released, and if those still don't work, possible try 314.22 (which was before they created the 320 branch and broke some stuff).

Believe it or not, new drivers can actually fix things!

Hmm. ok i was only wondering because TJ has the same problem and updated the drivers but still fail.

Hello dskagcommunity,
I need to tell you that I didn't run any short WU in the last 30 days, I don't dare to.
Later this week when I am at the computer with the 660 I will run a few short ones and let you know how they do.

Greetings from TJ

oh i read it like that because you answered me O.o ok then, i will upgrade the driver ^^

Hello dskagcommunity, as promised I would let you know about the SR's.
Well the first one did finished okay but with this "result" in the stderr:
# GPU 0 : 65C
SWAN : FATAL : Cuda driver error 716 in file 'swanlibnv2.cpp' in line 1963.
# SWAN swan_assert 0
# GPU [GeForce GTX 660] Platform [Windows] Rev [3203] VERSION [55]
# SWAN Device 0 :
# Name : GeForce GTX 660
That means that the clock has down clocked to half, so very slow processing now.
The PC had run for 10 and a half day with LR's and no such "error".
To me the SR are a pain on the 660. However 331.40 are not the latest beta drivers anymore.
I do hope your SR's do good. If you have time and willing you could try the latest drivers. Good luck.

Greetings from TJ

few weeks I have a problem. When im start a project manager Boinc gpu grid starts to work,then run the Chrome browser,or movie player program..or gpu-Z,youtube a whole computer slows down like in slow motion, if I in this manage to hit the slow mode mouse and clicking on the boinc manager and Pause only gpu grid, everything starts working normally-off in this

Already have fun few days, sometimes I succeed to run and feelings do not come into a slow-mode which subsequently repaired just reboot or reset. but immediately after start when windows boots up normally boinc manager and GPUGRID and I'll start windows normally uses 8.1 clean install nvidia driver geforce R331, after starting certain specific applications (Chrome, PotPlayer ..) to start mowing after again .. But it happened to me already without launching the program ... I checked everything but when it's almost a clean install, the problem is gpudrid and nvidia drivers and some acceleration in programs who work at the same time of GPUGRID ..

shorter this could be explained if I shot this video ...
but a longer time to work assignments from GPUGRID perfectly but recently launched this problem .. and the solution will be hard to find ..
I changed the HDD and SSD because of it whether it is really HW-no problem ..
strange that I simply could not fit bsod month because of faulty work of GPUGRID or other problems of labor, which is fully-forum :)
But he began to show me the problem-slow motion .. this is a situation in

I think it will be some conflict-GPUGRID-nvidia-acceleration program that uses the graphics card
because another project which was then the cpu is running at the same time with no problem

You are running Noelia Ins1p units on you 275 card which doesn't have enough memory this will cause what you describe.
