SHORT VERSION
=============

The libfabric group has steadily progressed in its API definition.  A prototype implementation is available (see below).  Detailed feedback is needed from the MPI community to help shape the API.  Please review, at a minimum, the simple pingpong source code to see the API in action (see below).

Please fill out this doodle to find a time for a webex to talk through the API and everyone's feedback:

MORE DETAIL
===========

Note that there is quite a bit more to the API than the calls that are shown in the sample pingpong program.  It is worth looking through the libfabrics/include/rdma header files, for example.

Here's a list of the compiled set of MPI requirements for the libfabric API:

And a link to the latest PPTX showing the libfabric architecture (endpoints, etc.):

    http://lists.openfabrics.org/pipermail/ofiwg/2014-June/000259.html

Please look through these documents, and look through the git repositories listed below and send detailed feedback.

I'm guessing that it will be worthwhile to have a webex to discuss all this stuff.  Please fill out this doodle (same as the doodle above) so that we can find a time to discuss:
