Subject: Re: [OMPI users] Compiling on different servers

As long as you compiled OMPI with support for OFED, yes. You will
need to have OFED installed on server 1 (even if you have no
OpenFabrics-capable devices) to build OMPI's OpenFabrics support.

FWIW, I do this kind of thing all the time: build OMPI on one machine
and NFS export it to all the machines in my cluster, some of which are
semi-heterogeneous (e.g., some have OFED installed, some do not, etc.).
