Well,
By turning off UCX compilation per Howard, things get a bit better in that
something happens! It's not a good something, as it seems to die with an
infiniband error. As this is an Omnipath system, is OpenMPI perhaps seeing
libverbs somewhere and compiling it in? To wit:

Hey Kiril,
Indeed, the pessimist message logging does not support threaded accesses. That
test is however overly cautious if you are initializing as multiple but then do
not perform concurrent accesses. Please verify that he NBP3.3 do
MPI_INIT_THREADS(MPI_THREAD_SINGLE), as doing other
Hi,
I’m doing some research on message logging protocols. It seems that Vprotocol
in Open MPI can wrap around communication calls and log messages, if enabled.
Unfortunately, when I try to use it with Open MPI- 4.0.0, I get an error:

Hi Matt,

verbs API and you have the necessary libraries in your system, openib btl finds
itself as a potential transport and prints the warning during its init (openib
