I'm currently working on code that should run on a number of different HPC machines with multiple GPUs. The machine I'm testing and developing my code hast just one GPU. The idea is to create a worker for each GPU found on the machine and then execute via a parfor loop some tasks on the GPUs. If I query gpuDeviceCount I get a 1 back but if I execute
parpool(1) % same is true for any number of workers
spmd
gpuDeviceCount
end
I always just get 0s back. Why are my workers unable to see the GPU?
