      Due to a change at SLURM version 20.11. By default SLURM systems now only allow one srun process to be active on each compute node. This can result in RSM subtasks timing out. If the solution phase of a calculation, takes longer than 5 minutes to complete. The workaround is to add the –overlap argument to the SLURM srun command. Which can be implemented by editing the file, {installdir}/v212/RSM/Config/xml/hpc_commands_SLURM.xml and replacing the lines, srun –ntasks=1 with the lines srun –overlap –ntasks=1
