Hello Arturo, Would you mind filing an issue against Open MPI and use the template to provide info we could use to help triage this problem?
https://github.com/open-mpi/ompi/issues/new Thanks, Howard From: users <users-boun...@lists.open-mpi.org> on behalf of Arturo Fernandez via users <users@lists.open-mpi.org> Reply-To: Open MPI Users <users@lists.open-mpi.org> Date: Monday, June 21, 2021 at 3:33 PM To: Open MPI Users <users@lists.open-mpi.org> Cc: Arturo Fernandez <afernan...@odyhpc.com> Subject: [EXTERNAL] [OMPI users] Error Signal code: Address not mapped (1) Hello, I'm getting the error message (with either v4.1.0 or v4.1.1) *** Process received signal *** Signal: Segmentation fault (11) Signal code: Address not mapped (1) Failing at address: (nil) *** End of error message *** Segmentation fault (core dumped) The AWS system is running CentOS8 but I don't think that is the problem. After some troubleshooting, the error seems to appear and disappear depending on the libfabric version. When the system uses libfabric-aws-1.10.2g everything sails smoothly, the problems appear when libfabric-aws is upgraded to 1.11.2. I've tried to understand the differences between these versions but it's beyond my expertise. Thanks, Arturo
