I have nearly completed my normal suite of tests.
Only slow emulated 32-bit ARM and MIPS remain.
This time around I've dropped big-endian PPC (because Open MPI did).
However, I've added Apple's public betas of Mac OSX High Sierra and Xcode 9.
I have no new issues to report, and the ones I raised
The fourth release candidate for Open MPI 3.0.0 is now available for download.
Changes since rc2 include:
* Better handling of OPAL_PREFIX for PMIx
* Update to hwloc 1.11.7
* Sync with PMIx 2.0.1
* Revert atomics behavior to that of the 2.x series
* usnic, openib, and portals4 bug fixes
* Add RE
