Hello Todor,

Open MPI and its “drivers” (UCX, PSM, etc.) browse /sys, /proc, and /dev
to determine what devices are available. Could it be that one of these
things is missing or different inside the container? Does ‘strace’
reveal anything?
The article at
<https://hpc.guix.info/blog/2019/12/optimized-and-portable-open-mpi-packaging/>
might shed some light on some of these things.
HTH,
Ludo’.
