Hey folks, whats happening to me ?

Any guesses ?

Using AMD 13.12 and HD 6950 gpu. Modified Fit works perfectly.

Greetings

I've seen this before with another user. For now, just run Modified Fit WUs. Try a detach/reattach and see what happens then. Are running with an app_config file? If so, please post it. Also, can you downgrade to CCC 13.1? or another known good driver?

<app_config>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>1</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>

<name>milkyway_separation__modified_fit</name>

</app_config>

Found only legacy driver for 13.1 !? Before that i tried 14.4 and beta 14.7 , same issue.

I reattached the project, no success :( still using 13.12 AMD drivers.

I will rise the cpu usage to .75 , and will see...no success...

Are you getting Blue Screens?

Just rejoined MW after long absence from BOINC. Also got computation error on first wu's I tried. Also 6950, same version of AMD drivers as Rantanplan. Frankly, I've forgotten most of the tweaks I used to use, so I'll wait to see if there's a resolution to this thread before trying a bunch of stuff.

I went back to an older driver, but opencl still errors out. The other task seems to run okay.

no, nothing happens when it appears.

Two things MilkyWay likes the 'release' version of drivers, not always the latest and greatest Beta drivers, nor the older ones either. The other thing is are you leaving a cpu core free just for the gpu to use? The gpu apps need alot of cpu power to keep the gpu fed and working optimally, if it is fighting for cpu time with a cpu workunit it can have problems.

4 cores free to crunsh, error in result :(

interesting...how can i disable platform 0 from OpenCL crunshing ?

Thru an cc_config.xml file kinda sorta like this:
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
<exclude_gpu>
<url>http://milkyway.cs.rpi.edu/milkyway/</url>
<device_num>0</device_num>
</exclude_gpu>
</options>
</cc_config>

Instead of using the <device_num>0</device_num> you could use this instead:

<type>intel_gpu</type>

Syntax is critical here, meaning if you get it wrong it will NOT work!! Capital letters DO count!! Here is the wiki on how it all works:

ok, gpu related, i know this, but CPU ?

No I can't think of a way right now.

Open cl ATI tasks still have computation error for me using 6950. The modified fit task seems to work fine, so I guess I'll just run that. Have no other cpu tasks running at all, so cpu load is not a problem.

I am running a 6950 with Catalyst 13.1 drivers and both types of work units are working fine. I can't remember exactly what it was but there is something quirky about the 6950 and it required the older drivers.

Hope that helps.

I also get this issue on my two 5970's. I am using the latest drivers on my windows 8.1 install.

Yep, see the thread I just bumped called 'All Milkyway@Home 1.02 tasks ending in computation error on HD6950'. Is also relevant to owners of 5800s & 5900s.
Without the above fix you can do mod fit WUs but not the MW v1.02 WUs.

Not having a free CPU core won't cause the WUs to error out, I know I've done it ;).
He probably needs the 13.1 driver & a proper driver clean out as per above thread.

Hm, rejoined MW just recently and right now I have a different issue.

My HD7790 doesn't get any WorkUnits at all - has the work distribution for ATI OpenCL been halted maybe ?

Sure you've got the GPU apps ticked in your online MW preferences?

Yep, another Host is chugging along just fine (NVidia GPU).

Looking at the Event Log, the AMD GPU Host was requesting GPU tasks and the reponse always was "Got 0 new tasks, Scheduler request complete".

For now it's busy with another project but I'll try again to get it some work tomorrow.

But if that doesn't work, I'm a bit at a loss there. I already toggled the option back & forth but it made no difference. Also, all Applications are allowed to run without restrictions.
So far, the host got Collatz and Einstein tasks without issues.
Only as I wanted to move to MilkyWay, I noted it not getting any work for the card...
