"""The Process Management Interface (PMI) has been used for quite some
time as a means of exchanging wireup information needed for
interprocess communication. However, meeting the significant
orchestration challenges presented by exascale systems requires
that the process-to-system interface evolve to permit a tighter
integration between the different components of the parallel
application and existing and future SMS solutions.
PMI Exascale (PMIx) addresses these needs by providing an extended
version of the PMI definitions specifically designed to support
exascale and beyond environments by: (a) adding flexibility to the
functionality expressed in the existing APIs, (b) augmenting the
interfaces with new APIs that provide extended capabilities, (c)
forging a collaboration between subsystem providers including
resource manager, fabric, file system, and programming library
developers, (d) establishing a standards-like body for maintaining
the definitions, and (e) providing a reference implementation of the
PMIx standard that demonstrates the desired level of scalability
while maintaining strict separation between it and the standard
itself."""
