Hi Sekerob,

thanks for your long and helpful post.

I have been out of the city for a few days. No I have reinstalled boinc and configured (hopefully) everything as you said.

I must admit, that I did not notice the Additional buffer settings before. I have wondered if I should set it to 10 days. But as you said, I set it to 2 days for now. And obviously the rest of the settings is done as you said.

@skgiven: Is the GPU never used to crunch WCG tasks? I though that GPU would speed up the crunching by a factor.

Thanks 2 U both

Hi,

by now everything works out fine. GPUGRID is crunching on the GPU and WCG is working on the CPU.

I just wonder, why a machine that does nothing but chrunching delivers such different results:

Can someone give me a hint where to search? All the settings are found above in this thread (or so I hope).

Thx, i will go through the logs and find out if this explains the volatility.
