Placing MPI ranks on the specific cores of Xeon Phi

[Shilpa_B_]

Hi..Is it possible to place the MPI ranks on the specific cores of Xeon Phi (1-60) during the native mode computation. All that I understand is that the scheduler assigns ranks in round robin fashion on all the nodes starting from the first available core. Is it possible to overwrite this?

You'll need to read the docs for the MPI of your choice.  You could go as far as giving full lists of assignments on each node, e.g. by I_MPI_PIN.....
