Synthesizing what I think I've learned over the past 24 hours,
[*]The PMIx implementation described at
<http://slurm.schedmd.com/SLUG15/PMIx.pdf> describes a
complete, upward-compatible [I hope!] highly-scalable (exascale)
replacement for the PMI-1 and PMI-2 job launch facilities
[*]The "PMIX" paper at
<http://slurm.schedmd.com/SLUG15/chakrabs-slug15.pdf>
describes creative ways to use and extend the existing PMI-2
interface to exascale levels which will [I hope!] be fully
compatible with the PMIx implementation
Clarifications and corrections gratefully accepted!

Hi Andy.
I honestly have no idea why those guys did that :-). We’ve known
about their efforts for awhile, but this is the first I’ve seen
them labeled as PMIX. Guess we do differ on the capitalization
of the last letter.
Anyway, the PMIx effort is already being integrated in several
popular RMs, including Slurm, so I imagine it’s a moot point
accept for possibly confusing people searching publications.

From the presentations at the Slurm Users' Group meeting,
<http://slurm.schedmd.com/SLUG15/chakrabs-slug15.pdf>
and <http://slurm.schedmd.com/SLUG15/PMIx.pdf>, it
appears that two implementations of an improved PMI interface,
both tagged "PMIX", are underway. Are these cooperating,
competing, or "only just realized that they could be
cooperating" activities?
