Cannot find MPS control daemon process

When I execute the command “nvidia-cuda-mps-control –d”, but cannot find MPS control daemon process. What is the problem and how can it be solved?

Hello chenmzh, did you execute the command as superuser? This has to be run with admin rights.

Beside that I would highly recommend checking out the MPS documentation and making sure this suits your needs. Unless you are setting up your own multi-node HPC system for CUDA compute tasks it might not be necessary to employ MPS.
