pmix

Process Management Interface for Exascale (PMIx)

OpenPMIx is an open source, non-copy-left licensed, and independent (i.e., not affiliated with any specific programming model code base) standalone library that supports application interactions with Resource Managers (RMs). It retains transparent compatibility with existing PMI-1 and PMI-2 definitions, and any future PMI releases. OpenPMIx also supports the Instant On initiative for rapid startup of applications at exascale and beyond, and works with the HPC community to define and implement new APIs that support evolving programming model requirements for application-RM interactions.
