Hi Patrick, Also it might not hurt to disable the Open IB BTL by setting
export OMPI_MCA_btl=^openib in your shell prior to invoking mpirun Howard From: users <users-boun...@lists.open-mpi.org> on behalf of "Heinz, Michael William via users" <users@lists.open-mpi.org> Reply-To: Open MPI Users <users@lists.open-mpi.org> Date: Monday, January 25, 2021 at 8:47 AM To: "users@lists.open-mpi.org" <users@lists.open-mpi.org> Cc: "Heinz, Michael William" <michael.william.he...@cornelisnetworks.com> Subject: [EXTERNAL] [OMPI users] OpenMPI 4.0.5 error with Omni-path Patrick, You really have to provide us some detailed information if you want assistance. At a minimum we need to know if you’re using the PSM2 MTL or the OFI MTL and what the actual error is. Please provide the actual command line you are having problems with, along with any errors. In addition, I recommend adding the following to your command line: -mca mtl_base_verbose 99 If you have a way to reproduce the problem quickly you might also want to add: -x PSM2_TRACEMASK=11 But that will add very detailed debug output to your command and you haven’t mentioned that PSM2 is failing, so it may not be useful.
