Nope. Still doesn't work. Still get the same computational error. I'm done until this BS issue is fixed.

I have the same issue. All computational errors. Looks like I missed the double credit window due to this! Grrrrr!

Anyways, here's what I'm running if it helps.

Boinc 7.0.15
AMD drivers 12.1
HD 6970
Windows 7

This all started happening after I upgraded both BOINC and my card drivers.

That wasn't for your error. Your error suggests the OpenCL library is broken or missing.

Atm it seems it's working fine.

Installed 6.10.60 again and afterwards http://www.arkayn.us/forum/index.php?PHPSESSID=f0483088d797862abe1bbb0a1b6bd4a2&action=downloads;sa=view;down=60 on my XP64

GTX 460 FTW 1GB (1.075V > 1.012V / 850MHz > 890MHz) / 6.10.60 / 275.33 XP32 OK
GTX 460 SC 768MB (763MHz > 820MHz) / 6.10.60 / 285.58 XP64 OK

Will change some things in nearby future such as drivers, voltages and speed and watch what happens.

I downgrade drivers to 11.9 and ran the 1.02 app_info.xml from Arkayn. I'm still getting a gpu crash within about 10sec of task start. All tasks failing.

Moving to a different project, really makes me sad though, only like 3 days from 5M. :(

After approx 01.00 UTC 15/2/2012 all 0.82 (ati14) GPU tasks deadline dated 27/2/2012 02:03++ failed with computation error.
All remaining unstarted GPU tasks have been aborted.
The option for no new tasks is initiated.

FWIW all other GPU tasks completed succesfully today AFAIK.

Please advise.

Your errors suggests rebooting.

Thanks Matt. That worked.

Care to elaborate?

This error does not occur if I run other GPU projects. Put another way .

If I HADN'T checked, asked, rebooted, re-tested:-

I'd still be blindly* running MW@H GPU tasks 24/7 costing me electricity/wear & tear doing nothing with my very expensive, now very rare hardware ... which I would prefer not to do.

* headless server

Suggestion. Issue a pro-tem-for-this-project "stop processing & stop accepting new tasks for this project" command and an Event log message for me to check why processing stopped, after e.g., 5th etc failed WU with the same "Computation failed" error. Just a thought.

The drivers aren't particularly unreliable. They sometimes get into a bad state where nothing works.

I am having similar problems.

My 24/7 rig: q6600 + 5830 win xp x32
CCC: 10.12
"Message from server: Catalyst Driver Version is Not OK for OpenCL app with this GPU"

this is running on a 24/7 machine so i look back and this error started occuring on 2/9/12 at 3:15pm pst


my main rig: q9550 + 5850 win 7 x64
CCC: 8.85
work is done in 2 seconds with computational error

dont know why

CCC: 10.12
"Message from server: Catalyst Driver Version is Not OK for OpenCL app with this GPU"

10.12 is ancient; you'll need something more recent. The most recent 12.1 should be fine.

I updated to 12.1 and got 2 valid WU's turned in today-otherwise lots of failures.

Apparently the unroll problem wasn't fixed until 1 driver later than I thought. You shouldn't get it anymore for anything newer than R700 with drivers older than 11.6

10.12 is ancient; you'll need something more recent. The most recent 12.1 should be fine.

they are stable though. upgrading to each CCC creates problems for my other programs.

Ever since 1.00 update been getting comp errors.

Is your BOINC data directory on some weird filesystem or a network share or something?

I think the app_info he used is for separation only; so he needs to add a part for nbody to run that too.

Is your BOINC data directory on some weird filesystem or a network share or something?

It's on an external HD FAT32 format.

Looking at the list of your WUs with errors.
2* simulation v1.02
1* nbody v0.84 (mt)

All 3 are showing the same error:
Failed to update checkpoint file ('separation_checkpoint_tmp' to 'separation_checkpoint') (2): No such file or directory

You could switch off checkpointing for separation because of the short runtimes on your gpu, but your problem isn't for separation alone.
It 'smells' like the external disk is the problem.
Can you try and move your BOINC dir to an internal drive?

The checkpoint file update is done using transactions if it's available on the system so that you don't lose a checkpoint in the event of a power failure at the wrong moment or anything like taht.

I remember checking and adding a fallback if the FS didn't support transactions but it looks like it's not there now. I'll readd that I guess but moving it to an NTFS partition would avoid the problem.

After a 9mth hiatus I thought I'd give MW a shot again but I'm am also getting every single WU erroring out :(.

Had to update drivers so it's now on Cat 12.1, updated BOINC to 6.12.34 (btw I also tried 7.0.18 but it couldn't detect my GPU!, so went back to v6).

Specs:-
Win XP 32, HD4830, C2Q Q6600, 4GB RAM(3.25 useable), P45 chipset.

Any ideas?

After a 9mth hiatus I thought I'd give MW a shot again but I'm am also getting every single WU erroring out :(.

Had to update drivers so it's now on Cat 12.1, updated BOINC to 6.12.34 (btw I also tried 7.0.18 but it couldn't detect my GPU!, so went back to v6).

Your driver installation is missing the OpenCL dll. The catalyst installer apparently offers an option to not install it (why I have no idea), but reinstall your drivers without unchecking the install APP SDK option in the custom install part.
