Hello,
I am using ompi-v1.8 and have come across the following error: -------------------------------------------------------------------------- Open MPI tried to bind a new process, but something went wrong. The process was killed without launching the target application. Your job will now abort. Local host: vegas17 Application name: trivial/test_get__trivial/c_hello Error message: hwloc_set_cpubind returned "Error" for bitmap "0,16" Location: odls_default_module.c:551 -------------------------------------------------------------------------- This happens when running a simple trivial test with the following command line: mpirun --map-by node --bind-to core -display-map -np 2 -mca pml ob1 …/trivial/test_get__trivial/c_hello What seems to eliminate this error is changing the binding policy from core to none (--bind-to none). The only nodes which are issuing this error are always the nodes which have GPUs in them. When running the same command line on other non-GPU nodes, there is no error. I’m using Slurm to allocate the nodes. Has anyone seen this issue or knows what’s wrong here? Thanks, Alina.
