[one-users] MPI Application

[Ruben S. Montero]

Hi Guilherme

There is *no* difference from the OpenMPI point of view between physical
MPI and virtual MPI cluster. Just do the same steps but always *in* the
VMs. I suggest you:

1.- Prepare one VM image as front-end. With the LRMS of your choice
(SGE...), NFS MPI libraries and the like

2.- Configure a VM as node that can be instantiated multiple times, so you
can instantiate multiple cluster nodes.

In summary, follow any guide or tutorial to setup a MPI cluster but use
your VMs as nodes. Do not install anything in the OpenNebula nodes.

Good Luck

Ruben
