The "simpleMultipleDevice" seems wrongly written in the SDK sample, for example, the "input" and "output" is reversed in the kernel.
Also it seems I can only use GPU to do calculation, someone told me to disable crossfire, I did it , then I can only find two GPUs in my system.(Used to be four).
Here is my sistem:
CPU: i7, Operatiing system: win 7 64 bit
GPU: two HD 5970.
This problem has bothered me for a long time, any explanations on this?
Thanks a lot.
