[OMPI users] Passing a rank specific argument to the JVM

Hi, I am trying to profile one of our applications and would like each rank to report to a profiler through a specific port. This is a Java program, so the way I would like to do this is to pass the port as a command line argument to the JVM. For example, mpirun -np 2 java MyProgram Note the po
