      Description

      Pegasus MPI Cluster's Test PM848 fails on Debian 10 (Buster). The version of mpirun installed is different.

      Example:

      No. of processors = 8

      SUCCESS: mpirun -np 8 echo 1
      FAILURE: mpirun -np 9 echo 1

      Fix:

      Set -np to `nproc`. Will work on all platforms.

      OR

      Add --oversubscribe flag, this addition will have to be conditionally based on mpirun's version.

      Select appropriate fix based on the purpose of the test case.
