so I’m using GTX 590 on ubuntu 10.04 64bit
recently I tried to update cuda toolkit to 4.2 version, so I updated the cuda driver and cuda toolkit,
then when i was trying to build the newest gpu computing sdk, I went successfully
however i got a problem, when i tried to run ./deviceQuery, this message appeared
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 10
-> invalid device ordinal
[deviceQuery] test results…
then tried to revert back to previous toolkit version 4.1 with it’s devdriver and computingsdk, however it didnt work, still the same error msg
anyone can help me about this?
