I've heard this argument more than once now and I don't agree. MPI 
installation is at our site de-coupled from the OFED installation (for quite 
a few reasons such as, different compilers, multiple versions, 
RM-integration, ...).

I'm sure there are quite a few that do use the OFED shipped MPIs but I'm 
equally certain I'm far from alone in building MPI on the side.

One vote for keeping MPI out of OFED,
 Petere
