@rhc54 This is a draft of what we were talking about on PMIx call. I'm still verifying the code but the conception should be clear. Could you take a look and see if you are OK with this.

I will also add the PMIx keys to indicate that RM has created directories and that it will clean them up for OMPI as we discussed. I will implement this as a separate commit.

@artpol84 artpol84 force-pushed the pmix_sdirs branch 2 times, most recently from 76f1718 to ec73484 Compare September 1, 2016 17:25

The keys are added but I need to test them with SLURM.

* enable OMPI to retrieve paths from RM through PMIx
* cleanups related to tempdirs.

As per today's PMIx telecon, this looks fine. Just replace your TODO comments with a note that we decided to let MCA params override the RM directive and we should be good.

Thanks!
