Assigning each CPU with a GPU

[Zhenyang]

Hence, what you want to focus on is ensuring that each pyfr instance uses the appropriate IB adapter (5_0, 5_1 for GPU0 and GPU1, 5_2, 5_2 for GPU2 and GPU3, etc) and that MPI is properly CUDA aware. This should give you the best overall performance.

Hi Freddie, thanks for your reply. I am not sure how do that exactly. Can you indicate it more detailly?

And according to our last discussion PyFR 1.13.0: CUDAOSError - #14 by Zhenyang, I recompiled my mpi library without cuda support. Should I turn back to CUDA aware MPI?

Best wishes,
Zhenyang
