Re: [OMPI users] Xgrid and choosing agents...

Hi, So you have 4 nodes each one with 2 processors, each processor 4-core - quad-core. So you have capacity for 32 process in parallel. I think that only using the hostfile is enough is how I use. If you to specify a specific host or a different sequence, the mpirun will obey the host
