To address Raymond Muno's question:
"Any estimate on when OpenMPI 4.2 will be released?"
Howard and I are the release managers for v4.0.2. We expect to publish it tomorrow, assuming no show-stop bugs come up in testing this week.

We are now using OpenMPI 4.0.2RC2 and RC3 compiled (with Intel, PGI and
GCC) with MLNX_OFED 4.7 (released a couple days ago). This supplies UCX
1.7. So far, it seems like things are working well.

Thanks Raymond; I have filed an issue for this on Github and tagged the
relevant Mellanox people:

As a test, I rebooted a set of nodes. The user could run on 480 cores,
on 5 nodes. We could not run beyond two nodes previous to that.
We still get the VM_UNMAP warning, however.

Can you try the latest 4.0.2rc tarball? We're very, very close to releasing
v4.0.2...
I don't know if there's a specific UCX fix in there, but there are a ton of
other good bug fixes in there since v4.0.1.

We are primarily using OpenMPI 3.1.4 but also have 4.0.1 installed.
On our cluster, we were running CentOS 7.5 with updates, alongside
MLNX_OFED 4.5.x. OpenMPI was compiled with GCC, Intel, PGI and AOCC
compilers. We could run with no issues.
To accommodate updates needed to get our IB gear
