Given a growing use of PRRTE plus OMPI’s announced plans to phase out ORTE in
favor of PRRTE, it seems the time has come to begin generating formal releases
of PRRTE. Accordingly, I have created a v3.0.0 release candidate for folks to
Note that the first number in the version triplet represents the PMIx level
being supported - in this case, the release candidate supports PMIx v3 of the
Standard. I know we haven’t yet released that formal document, but it is
available in PR form and should be released fairly soon.
This release candidate actually includes support for some of the
under-development PMIx v4 APIs. However, the version triplet is based on what
we consider to be the “production” level of PRRTE, and the PMIx v4 support
included in the current code is truly at the prototype level. Those who want to
experiment with those interfaces are welcome to build this release against the
PMIx master branch (which is at the cutting edge of PMIx v4 development) and
work with them. Now that we have started formal releases, we’ll do a better job
of branching early prior to introducing new APIs so we won’t have this mix
Note that PRRTE contains _no_ embedded code. Thus, building it requires that
you have libevent, hwloc, and some version of PMIx installed - if not in
standard locations, you’ll need to use the configure arguments to point to
them. Any version of PMIx that is at least v2.0 is supported - PRRTE does _not_
support the PMIx v1 series.
Please give this a whirl and post any comments/bugs to the github issues.
