But if you want to run an MPI application in all the ports belonging to
one partition (e.g: partition2 in my previous exmple) a conflict will arise
as most of the MPI implementations have provision of allowing only one
Pkey index (e.g: ib_pkey_ix in openMPI). This problem can be easily solved
by storing pkey value at the same pkey index in all ports belonging to same
partition.
