NOTICES
SLURM INTERACTIVE SESSIONS: IMPORTANT Please share amongst your peers, especially if your department/group has internal documentation on interactive sessions.
SchedMD is recommending that you use salloc instead of srun to start an interactive session.
Doing this also solves the issue of invoking MPI inside of srun, which is an srun inside of an srun. If you simply use salloc to get the reservation, you can then use srun to hook into that reservation if/as needed.
srun is still available, but it is no longer recommended as the command to start interactive sessions.
See examples in our docs: https://docs.rc.fas.harvard.edu/kb/running-jobs/#Interactive_jobs_and_salloc SchedMD command documentation: https://slurm.schedmd.com/salloc.html
