[OMPI users] OpenMPI crashes with TCP connection error

2023-06-15 Thread Mccall, Kurt E. (MSFC-EV41) via users
My job immediately crashes with the error message below. I don’t know where to begin looking for the cause of the error, or what information to provide to help you understand it. Maybe you could clue me in 😊. I am on RedHat 4.18.0, using Slurm 20.11.8 and OpenMPI 4.1.5 compiled with gcc 8.5

Hi Kurt, Without knowing your exact MPI launch command, my cristal orb thinks you might want to try the -mpi=pmix flag for srun as documented for slurm+openmpi: https://slurm.schedmd.com/mpi_guide.html#open_mpi -Joachim From: users on behalf of Mccall, Kurt E.
