Subject: [OMPI users] gpudirect p2p (again)?
From: Crni Gorac (cgorac_at_[hidden])

Trying to examine CUDA support in OpenMPI, using OpenMPI current
feature series (v1.7). There was a question on this mailing list back
in October 2011
(http://www.open-mpi.org/community/lists/users/2011/10/17539.php),
about OpenMPI being able to use P2P transfers in case when two MPI
processed involved in the transfer operation happens to execute on the
same machine, and the answer was that this feature is being
implemented. So my question is - what is the current status here, is
this feature supported now?

Thanks.
