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 iswarning only; your job will continue, though performance maybe 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 boundSet 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!
