You shouldn't need anything special -- I don't. (It's common to run,
say, one process per core for benchmarking.) Running
mpirun -tag-output -np 14 -npernode 7 hostname

When you say "it fails", what do you mean? That it doesn't run at all, or that
it still fills each node, or...?

Hello All.
I am trying to run a parallel application that should use one core less than
the no of cores that are available on the system. Are there any flags that i
can use to specify this.
i tried using the following syntax with machinefile
openmpi-1.4-BM/bin/mpirun -np 14 -npernode 7 -machine
