Notable differences #
First line of job script must be #!<shell>, e.g.:
#!/bin/bash
Slurm jobs start in the submission directory rather than in home directory.
Slurm jobs have stdout and stderr output log files combined by default.
Use mpirun in Slurm jobs in place of mpiexec.
For interactive jobs you can use salloc command, e.g.:
salloc --ntasks=8 --time=1:00:00
Torque commands support #
Running old Torque commands is not supported since January, 2023. Please use Slurm commands and parameters.
