During the Jan. 25-26, 2022 Sapelo2 maintenance, the Slurm queueing software was updated to version 21.08.5.

Changes needed in the job submission scripts:

1. If your application/program uses the MPI libraries listed below, please run the binary with srun instead of mpirun or mpiexec:

  • OpenMPI versions up to 3.1.4
  • foss/2019b and fosscuda/2019b toolchains
  • Intel MPI provided by the intel/2019b and intel/2020b modules

2. If your application uses MVAPICH2 (e.g. MVAPICH2/2.3.4-GCC-8.3.0), please run the binary with srun --mpi=pmi2 instead of mpirun or mpiexec.
