These WUs were running 4 x slower than normal

I found this on 3 boxes with different cards
The Stderr output files is also funny with no line breaks


I noticed that at the same time WCG Beta 6.12 CPU WUs were running
Could it be a coincidence?

I just received another Beta Test 6.12 wu from WCG

The GPU activity is dropping to 60% when the WCG app is running.
When I suspend the wu GPU activity returns to 99%

Might not be since they could hog the CPU from the D.net Client process, which needs it from time to time to feed work for GPU. Could you try to bump the priority to 6 or 9 to see if that helps the D.net Client getting CPU as it needs? (Run Anonymous platform and edit the .ini file line that currently should have priority=4 on it.) Or simply bump the process (for the dnetc518 prefixed exe/process only) priority to Normal or High as a test.

I'm thinking to bump priority value to 9 in the next app version in the hope it helps when there's some CPU hoggers around. This is for GPU only and also probably only Stream as CUDA might not be affected.

I've also witnessed some bizarre behavior from the ATI Runtime or D.net kernel on my primary host that seems to get affected by anything around it, including the moon phase. :( This might be unrelated to normality, though, since the 5970 card on that host was acting up.

Thanks Teemu
Will try that when the release wu's again

You are right. wcg_bera13_vina... is a CPU hogger.
When 2 is running on a dual proc pc it uses all the CPU time.
Upping the priority of dnetc518...exe in Win task manager help but is only valid for the current running Moo wu

I edited dnetc-1.00.ini and changed the value of processor usage from 4 to 9
This works well and the GPU now gets CPU time again to update

Thanks again for your advice
