16.1. PMIx v6.x series

This file contains all the NEWS updates for the PMIx v6.x series, in reverse chronological order.

16.1.1. 6.0.0 – TBD

Important

This is the first release in the v6 family. The intent for this series is to provide regular “reference tags”, effectively serving as milestones for any development that might occur after the project achieved a stable landing zone at the conclusion of the v5 series. It is expected, therefore, that releases shall be infrequent and rare occurrences, primarily driven by the completion of some significant feature or some particularly critical bug fix.

For this initial release, that feature is completion of the Group family of APIs. This includes support for all three of the group construction modes, including the new “bootstrap” method. A description of each mode can be found in the Group Construction section of the documentation.

Note that proper execution of the various group construction modes requires that the host provide the necessary backend support. Please check with your host provider to ensure it is available, or feel free to use the PMIx Reference RunTime Environment (PRRTE) - you will require v4.0 or above.

A full list of individual changes will not be provided here, but will commence with the v6.0.1 release.
