I setup xorg conf using:
aticonfig --adapter=all --initial -f
CLInfo reports only one GPU (first core of first 5970)
if I setup xorg using:
aticonfig --adapter=0 --initial -f
CLInfo repots two GPUs (first and second core of first 5970)
Have u activated both GPUs?
clinfo reports 3 app devices:
first two is 7970 gpu, third is CPU.
"is it driver bug, sdk bug, boinc bug or something else?"
If that's case, run the multi-GPU sample in the SDK. If it passes, chances are it's not a driver bug or sdk bug.
i''l try. where is it located and how it is named?
solved. it is BOINC detection problem.
