Open MPI State of the Union X
Authors: Dr. Jeffrey Squyres (Cisco Systems)
Abstract: It's been another great year for Open MPI. We've added new features, improved performance, completed MPI-3.1, and are continuing to drive the state of the art in HPC. We'll discuss what Open MPI has accomplished over the past year and present a roadmap for next year.
One of Open MPI's strength lies in its diversity: we represent many different viewpoints from across the HPC community. To that end, we'll have a Q&A session to address questions and comments from our community.
Join us at the BOF to hear a state of the union for Open MPI. New contributors are welcome!
Long Description: The Open MPI community has been hard at work on new and useful
features, tweaking performance improvements, and overall improving the
structure and clarity of the code. Our emphasis over the last year has
been working towards stability in the context of a full MPI-3.1
conformance (be sure to see the MPI Forum BOF for details on where MPI
itself is going).
Over the past few years, we have found that the BOF format makes it
difficult to solicit questions and feedback from the community who
attends our BOF. However, we consider such questions and feedback
vital to the continuation of Open MPI -- our users and community are a
huge portion of what helps Open MPI keep evolving in a direction that
is genuinely useful. This year, we are soliciting questions from the
web before the BOF; send us your questions, comments, and feedback and
we'll discuss them during the BOF:
In this BOF, we'll present where Open MPI currently is and where it is
going. Here are some of the highlights of what will be covered during
- Retire the 1.10.x series
- Continue the 2.x release series; fork for 3.x series
- Performance improvements
- Scalability improvements
- Multithreading and asynchronous progress support
- Improvements on one-sided operations
- Supporting more hardware platforms and networks
- Support for new collective algorithms, including direct hardware support
Be part of the discussion: submit your questions ahead of time and
come hear where Open MPI is going, and how you can (and should!) join
