[slurm-users] Jobs exiting together

Recently, i have built an hpc cluster with slurm as workload. The test jobs with quatum chemistry codes have worked fine. However, production jobs with lammps have shown an unexpected behavior when the first job completed, normally or not, cause the termination of the others in the same compute node. Initially, I thought that was due to mpi malfunction, but this behavior is algo observed for serial lammps code. The lammps group said to me that behavior could be generated by slurm. My question to you is about what parameter in slurm.conf could be responsible for the termination of the other jobs. I am using an epilogue script that work normally in another cluster.

Thanks.
