I can see from the mails and from my personal experience that most of the "end users" do not need/use the MPI coming as part of OFED (they have many different MPI installed in their clusters), as we can see distro are not using it and also some (if not all) of OFED binary package providers (i.e

I agree with DK from OSU. There are clear advantages to having MPI included with OFED. Not only will it make testing of a complete solution easier by both OFED and MPI suppliers, but it will also improve ease of use for end users. As DK points out there are continual improvements in MPIs whic

A few clarifications are probably worthwhile at this point. 1. No one is suggesting divorcing MPI from the OFED testing/release cycle. It's obviously a Good Thing (and has been stated multiple times on this thread). It is easy to indicate "good combos" of MPI and OFED in documentation and
