The OMPI cmd line converts "--mca ptl_tcp_remote_connections 1” to OMPI_MCA_
ptl_tcp_remote_connections, which is not recognized by PMIx. PMIx is looking
for PMIX_MCA_ptl_tcp_remote_connections. The only way to set PMIx MCA params
for the code embedded in OMPI is to put them in your environment
What is exactly the issue you are facing ?
You also need to force the subnet used by oob/tcp
mpirun —mca oob_tcp_if_include 10.233.0.0/19 ...
iirc, Open MPI might discard addresses from a bridge interface, but I do
not exactly remember if it affects both btl/tcp and/or oob/tcp and/or none
by defa
But what about remote connections parameter? Why is it not set?
