Is there a limit to how many processes can use CUDA at the same time? I just setup a new Linux workstation and am delving into FreeSurfer w/ CUDA. I'm getting the following error:
Acquiring CUDA device
Using default device
CUDA Error in file 'devicemanagement.cu' on line 46 : all CUDA-capable devices are busy or unavailable.
