Hi, I mean the node that I run mpirun command from. I use condor as a scheduler but I need to benchmark the cluster either from condor or directly from open MPI. when I ran mpirun from a machine and checking the memory status for the three machines that I have it appear that the memory usage increased just in the same machine.
