Hello all, I am having an issue submitting mpi jobs via sbatch using Intel MPI 2019 Update 1. The job ends with a segmentation fault immediately:
[user@head mpihello]$ cat mpihello-intelmpi.out.62 srun: error: node003: task 0: Segmentation fault srun: error: node004: task 0: Segmentation fault [mpiexec@node002] main (../../../../../src/pm/i_hydra/mpiexec/mpiexec.c:2024): downstream was killed by signal 11 (Segmentation fault) Here is what the sbatch script looks like: #!/bin/bash #SBATCH --job-name=mpihello-intelmpi #SBATCH --output=mpihello-intelmpi.out.%j #SBATCH --error=mpihello-intelmpi.err.%j #SBATCH -N 3 --tasks-per-node=4 #SBATCH --time=10:00 #SBATCH --mem-per-cpu=100 /shared/intel/compilers_and_libraries/linux/mpi/intel64/bin/mpirun /home/usr/mpihello/mpihello-intelmpi To simplify things, I have tried launching a simple 'hostname' command in place of mpihello-intelmpi, but I get the same segmentation fault issue. Addtionally, I can directly launch the simple mpihello program as well as a 'hostname' command on the command line without issue. Any ideas on what is going on?
