Real-Time Message Passing Specification based on MPI
[MPI/RT Logo]
(MPI is the Message-Passing Interface)

This is the home page of the MPI/RT Forum. Look for regular updates,
improvements, new papers and drafts, as well as announcements of interest. MPI/RT is the one and only real-time parallel message passing middleware standard.
It was an offshoot of the MPI-2 Forum in the late 1990's, but is an independent de facto standard.

The final approved version of the MPI/RT 1.1 standard is now available in Postscript (PS) and Acrobat (PDF) formats.

The previously approved MPI/RT 1.0 standard is also available in Postscript (PS) and Acrobat (PDF) formats.

The MPI/RT Forum is dormant currently.

MPI/RT Forum meetings were open meetings, and all interested individuals,
and organizations were able to participate by e-mail, and/or by attending
meetings of the Forum. All attendees at meetings participate in
informal (straw) votes, and institutions have 1 vote on official
decisions if they attend two of the last three meetings, including
the one then currently in session.

Here are key goals of the MPI/RT Forum.
* Create integrated messaging, scheduling, and parallel programming API
together with syntax and semantics to support the emerging computational
hierarchies of node architectures and gigabit/s networks efficiently.
* Expand the horizons of performance-portable real-time programming
* Support multiple real-time paradigms
* Enhance the performance of Messaging over MPI-1 and MPI-2
* Catalyze a new generation of portable parallel applications that
require or benefit from the explicit use of time

A more complete overview is available as Tutorial Overview(Under Construction)
