Hello Rayne Lancer and list
Rayne, if you tell the command you use to launch the job, you may get a
faster answer from the list.
I agree with others who guessed that your program may running on your
local machine only,

Best guess, without seeing the mpirun cmd line, is that all the procs
are executing on one computer. In that scenario, we default to using
shared memory, so there would be no traffic going across the network.
