It's not clear if that message is being emitted by Open MPI. It does say it's falling back to a different behavior if libnuma.so is not found, so it appears if it's treating it as a warning, not an error. ________________________________ From: users <users-boun...@lists.open-mpi.org> on behalf of Luis Cebamanos via users <users@lists.open-mpi.org> Sent: Wednesday, July 19, 2023 10:09 AM To: users@lists.open-mpi.org <users@lists.open-mpi.org> Cc: Luis Cebamanos <luic...@gmail.com> Subject: [OMPI users] libnuma.so error
Hello, I was wondering if anyone has ever seen the following runtime error: mpirun -np 32 ./hello ..... [LOG_CAT_SBGP] libnuma.so: cannot open shared object file: No such file or directory [LOG_CAT_SBGP] Failed to dlopen libnuma.so. Fallback to GROUP_BY_SOCKET manual. ..... The funny thing is that the binary is executed despite the errors. What could be causing it? Regards, Lusi
