InsideHPC podcast: MPI collaboration with OpenFabrics

January 30, 2014 at 11:03 am PST

In my last blog post, I described a new collaboration between the MPI community and the OpenFabrics verbs community.

The collaboration started with the OpenFrameworks group asking the MPI community to list its requirements for a lower layer network API to the OpenFabrics OpenFrameworks working group.

In that last blog post, I posted an abbreviated set of slides with the first part of this MPI community feedback.  Since then, I have finished collating the feedback from the MPI community and have assembled a full set of slides.

Design discussions have been progressing within the “OpenFrameworks” working group in OpenFabrics. Progress has mainly occurred in the form of emails and weekly conference calls. Two weeks ago, Sean asked me to gather feedback about what an MPI implementation would want from a new underlying network API, and present that feedback to the libfabric group.

So I asked the MPI community.
