Hi,

I have two GPU devices in my system ,one is HD6850 and another is integrate HD6650D. Is there any way to use these two devices in the same time? There's always only one GPU device shown in the openCL program(SimpleMultidevice) even though I've establish the crossfire chain between two devices.

My OS is Ubuntu 11.04 Natty and the graphic driver version is 11.7

thanks

try run "export COMPUTE=:0" or "export DISPLAY=:0" and then SimpleMultiDevice

Thanks for replying, Micah

I Finally found the solution!!

Using command "sudo aticonfig --adapter=all --initial -f" to initialize all devices, then all devices will be dectected
