[OMPI users] Differences between hostfile in LAM-MPI and OPEN MPI.

Hi all: I have been using LAM MPI and for certain reasons wanted to move to OPEN MPI. I want to know the differences in hostfile between LAM MPI and OPNE MPI. What exactly needs to be introduced in the hostfile for OPEN MPI and what are the options. Thanks, Siamak

[OMPI users] Number of processes and number of the cores.

I have a question about using the open mpi. I want to tie "N" number of processes to one core and "M" number of processes to another core. I want to know if open mpi is capable of doing that. Thanks, Siamak
