I am working with CUDA 6.5:
Though when I run the sample simpleCUFFT_MGPU
result = cufftXtSetGPUs (plan_input, nGPUs, whichGPUs);
CUFFT_INVALID_DEVICE An invalid GPU index was specified.
Though when I run
I get 2 CUDA Devices.
I run this code over a SLI connection.
Anybody know what is going on, and how I can resolve this?
