Jimmy:
I have no experience with this, but assume that you just can't tie programs to
processors when running under your docker installation. That's what I see
here, for example:

*** Caution: EXTERNAL Sender ***
Dear all,
I built a Docker image from dealii/dealii:v9.2.0-focal from the dockerhub.
When I ran mpirun I got the following warning
*WARNING: Open MPI tried to bind a process but failed. This is
warning only; your job will continue, though performance may
be degraded.
Local host: 8f3a6d698b99
Application name: ./myprogram
Error message: failed to bind memory
Location: rtc_hwloc.c:447*
I also saw the similar warning as the program ran
*3 more processes have sent help message help-orte-odls-default.txt / memory
not bound
Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error
messages*
I can still gain some speed using multiple cores, but the gain is not that
much.
Neither the --bind-to core or hwthread option can solve this issue.
Do you have any thoughts? Thank you!
Best Regards,
Jimmy
