Hi Ben,

Thanks for the code.

I am getting this error though. I know it is to do with the time-out settings, but don't know what to do from here. My Quadro 1000M does not appear to be speeding up my ffts etc.

Warning: An unexpected error occurred during CUDA execution. The CUDA error was:
CUDA_ERROR_LAUNCH_TIMEOUT.
