[mvapich-discuss] Porting OSU MPI to a new network fabric

[dpchoudh .]

Hello OSU developers

Perhaps this question is a bit naive, but let me ask it anyway:

How hard would it be to add support for a new network fabric to the
OSU MPI stack? Is there any 'How-To' kind of documentation on this?

To put a bit of context into the question, I believe Texas Instruments
has ported OpenMPI to support their proprietary Hlink and (open
source?) rapidIO networks. Many years back I attempted a similar feat
for the Dune SAND fabric (now part of Broadcom) by implementing a new
BTL to OpenMPI.

Is there any example or documentation of doing something similar with
OSU implementation?

Thank you very much for any guidance.
