Hi all.
Actually I'm implementing an algorithm that creates a process grid and
divides it into row and column communicators as follows:
col_comm0 col_comm1 col_comm2 col_comm3
row_comm0 P0 P1 P2 P3
row_comm1 P4 P5 P6
Daniel,
There are no timeouts in OMPI with the exception of the initial connection
over TCP, where we use the socket timeout to prevent deadlocks. As you
already did quite a few communicator duplications and other collective
communications before you see the timeout, we need more info about this.

In brief, when I install openmpi@4.1.0 with ucx and xpmem fabrics, the

by which it is loaded into
