I've implemented and tested this in ./rules.

Ok. I've just disabled support as necessary for archs with openjdk issues.
While a riscv64 build has not yet occurred (awaiting in queue to see),
all issues on all other archs should now be resolved,
making the transition possible.

Oh, really, they fixed that? I already had given up hopes and therefore ignored
the thread on github out of frustration.


The other non-release archs were failing due to missing dependencies: in
particular java support (not used by any package in stable/testing) and
pmix (new; not used in testing/stable; pmix enables scaling to ~100,000+
nodes, which is unlikely to be needed).


I am working on fixing the remaining OpenJDK issues. I'm an upstream
committer in the OpenJDK project, so I can commit all changes myself.


So, the expected changes to mpi-defaults will no longer be needed.

Yay, thanks so much for this!

Adrian

As of 3.0.1, openmpi now works on Big-Endian powerpc (which was to be a
problem; it had been dropped upstream because of an unknown bug, now fixed).

The other non-release archs were failing due to missing dependencies: in
particular java support (not used by any package in stable/testing) and
pmix (new; not used in testing/stable; pmix enables scaling to ~100,000+
nodes, which is unlikely to be needed).

So, the expected changes to mpi-defaults will no longer be needed.
