Hi Sean,

I am pleased that you are putting in the effort to enable the existing OFED user base to continue using its
code without changes to the XRC calls.

Regarding XRC and MPI, see below.

You are correct, mvapich does not use XRC.
openMPI uses XRC, so hopefully you can use openMPI to test out your XRC stuff.

You can contact Jeff Squyres for details/help.

In the meantime, I include the following from the ewg list:

Hi Jeff,
The place for the Open MPI on the new server is under:
/var/www/openfabrics.org/downloads/openmpi/   (http://www.openfabrics.org/downloads/openmpi/)

I updated Open MPI version there to v1.4.3.
