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.

I tried also --host but it does not work correctly in benchmarking the cluster so does any one use openMPI in benchmarking a cluster or does any one knows how to make openMPI divids the parallel job equally to every processor on the cluster.
