Just got an ATI 1950 and seem to have followed the instructions, but I keep getting EUE (or is it UEU) on every work unit immediately (went from 600 WUs to about 1300 overnight (no points from them). Any idea what might be happening.
I went through Stanford's website to get to ATI and the only available driver was 7.1. Is this the problem?
I'll defer to someone else on this. I have no clue about he ATI cards.
The problem is the Catalyst 7.1 driver. Check out the comments on Catalyst versions:
"This is relevant to anyone folding with a GPU at present.
"The new Catalyst drivers released today 2007/01/10, version 7.1 (8.33) do not work with regard to folding on your GPU. The new drivers will cause the folding GPU core to continuously EUE on WUs, producing an "mdrun_gpu returned 114" error.
"The only versions of Catalyst that work with the GPU client are:
6.5
6.10
6.11
"The GPU client will work with these drivers with a significant performance hit:
6.6
6.7
"The following drivers do not work at all with the GPU client:
6.8
6.9
6.12
7.1"
And for software gurus that enjoy writing low level drivers, here's a little tidbit for an ATI engineer:
"It appears to be a compiler bug that's still standing. I thought we had a fix going into 7.1, but it apparently won't make it until 7.2. The issue seems to be that drivers go to QA long before they get released, and if we don't catch the bug early enough along, we miss getting a fix in the release. The other issue is that we've been running down other issues, like attempting G80 support, so we've been lax about updating the regression test we've given AMD. Just to annoy us and them, the 7.1 driver does pass the regression we gave them, but the current WUs take a slightly different code path."
Drop back to 6.11 and all should be fine.
