Hi folks I'm planning on removing the OPAL dss (pack/unpack) code as part of my work to reduce the code base I historically supported. The pack/unpack functionality is now in PMIx (has been since v3.0 was released), and so we had duplicate capabilities spread across OPAL and PRRTE. I have already removed the PRRTE code in favor of unifying on PMIx as the lowest common denominator.
The following PR removes OPAL dss and an "opal_tree" class that called it but wasn't used anywhere in the code: https://github.com/open-mpi/ompi/pull/8492 I have updated the very few places in OMPI/OSHMEM that touched the dss to use the PMIx equivalents. Please take a look and note any concerns on the PR. Minus any objections, I'll plan on committing this after next Tuesday's telecon. Thanks Ralph
