I've had several of these give an Error While Computing. Anyone else? These WU's seem to estimate at almost twice the computing time as I normally have.

I reported it 4 days ago for G92 cards (compute capability 1.1) like 9800GT, 8800 GT (G92)...

What drivers are you using?

DigitalDingus is using two 9600 GSO (767MB) cards with driver: 19745
(Q9450, XP x86).
The fail times look random:

I would suggest you try the latest drivers 25896. If you keep getting failures try to find out what else is running when these tasks crash (if anything).

Tapio, your task failed after 4sec GPU time. Some tasks seem to fail within 20sec. These are not very significant and do not reduce your contribution by much. Your card seems to be running well.

@skgiven,

I had the same problems with windows xp pro + gts250 + 258.96 driver after a lot of hours processing. See other thread.

Success

Will try the newer nVidia drivers, if any exist. Just upgraded to the latest BOINC in case it made a difference, but it did not. Other than that, I'll be crunching Collatz for a while I think.

Driver 258.96 exists for this card.
Please try it!

Good luck

Same problem here unfortunatly. Theres something wrong with those kashif units ...

@skgiven

Hi Kev,

Again after several hours (6) processing aborted. Windows XP-pro - gts250 258.96.
Gives also windows-message and waiting for answer, so no further processing during the night. I do not like this kind of errors. Do not send them anymore to this type of gpu-cards, please?
Good luck.

The HIVPR_n1_bound tasks seem very troublesome on CC1.1 cards. I made suggestions to allow crunchers to opt out of crunching some task types. It would involve some work for the scientists on the project design and server layout. If GDF can get it implemented it would allow crunchers to deselect troublesome projects, which would make it useful for other problems too.
Did an update try to automatically install on your system overnight?
I think the issue primarily relates to crunching those tasks, and only occasionally appears for other tasks, so perhaps this can be worked around by the programmers; you managed to crunch two revlo_TRYP work units in the last couple of days, so the card is still a useful, working card. We just need you to crunch the good tasks for that type of card.

The error from GPUgrid (HIVPR) causes a windows-error-message, which was waiting for a reply (send or no send to Microsoft). So all GPU-tasks were waiting during the night.
Keep on crunching!

I expect the Microsoft Error was along the lines of,
acemd2_6.05_windows_intelx86__cuda *32 has stopped working.
If you are sitting at the compter and see this error message pop-up, sometimes you can press the system restart button (on the computer case) and when it restarts the task is often able to pickup where from the last checkpoint; so you don't loose the task. That would not work after a minute never mind sometime overnight.
I'm guessing you have already restarted the system.

Do you know from the logs if a system update occured at that time of the error message (error logs), or some backup, defrag or other heavy CPU app ran - just in case something other than the task/driver is at fault here?

Hi Kev,

I use this machine only for crunching 24/7, so no back-up, no updates etc.
Just Gpugrid and RNA or Ibercivis ore Freehal. I do no have to restart this system.

Success!

I have the same problems with this card:

NVIDIA GPU 0: GeForce 9600 GT (driver version 25721, CUDA version 3010, compute capability 1.1, 496MB, 218 GFLOPS peak)

here's an example:
MDIO ERROR: cannot open file "restart.coor"
SWAN : FATAL : Failure executing kernel sync [PmeRealSpace_compute_forces_kernel] [999]
Assertion failed: 0, file swanlib_nv.cpp, line 121

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Thanks for reporting the error. The same error has been posted up several times now, and the developers are aware of it.
A driver bug is catching out the applications when they run on CC1.1 cards. It does not always occur but is a concern. With long complex GPU calculations the odd error is always expected, but these tasks are more problematic than others.
Several suggestions and potential work around’s have been made.

I expect the Microsoft Error was along the lines of,
acemd2_6.05_windows_intelx86__cuda *32 has stopped working.
If you are sitting at the compter and see this error message pop-up, sometimes you can press the system restart button (on the computer case) and when it restarts the task is often able to pickup where from the last checkpoint; so you don't loose the task. That would not work after a minute never mind sometime overnight.

I did this trick several times over the last month (four 9800GT cards).
System restart without clicking away the "error message pop-up" worked for me mostly - even hours after the error happend.

With the current KASHIF_HIVPR_*_bound* (*_unbound*) errors it worked never.

Knight Who Says Ni N!

Fred ... you posted results from a good run out of a 480 and it does not look like you are even running a 9800 anymore so I'm not sure wehere you were going with that.

Thanks - Steve

Fred use to have a GTX470, and is now using a GTX480. That task completed on his 480 but failed on a GTX460 (not a 9800GTX+). I did see a 9800 failure against one of his GTX470 successes.

Fred, keep your good cards hooked up to GPUGrid, a GTX480 would be wasted anywhere else.
