Whenever I run MPI application, it seems rank numbers get different.

Hello,

   It sounds like MPI Process Pinning is not working? It should. Could you provide your job script and launching mpirun command? Meanwhile, here are defaults settings for Process Pinning:

You can search through the online documentation regarding each of these settings. Of course, please do ask questions as well.

Cheers,
