Where the MPI interacts with InfiniBand?

[gnanam]

Hi!,
I'm new to InfiniBand & MPI. Currently i go through the code base of
OFED(Open Fabrics).
Could you please tell me, where the MPI api's interact with the
InfiniBand architecture?

Thanks,
Gnana

Hi Gana,
These links should answer your questions:

As for OpenMPI, it's over OFA verbs (libibverbs)
