| Slurm Basic Commands | 19 June 2019 | merlin6_sidebar | /merlin6/slurm-basics.html |
In this document some basic commands for using Slurm are showed. Advanced examples for some of these
are explained in other Merlin6 Slurm pages. You can always use man <command> pages for more
information about options and examples.
Basic commands
Useful commands for the slurm:
sinfo # to see the name of nodes, their occupancy,
# name of slurm partitions, limits (try out with "-l" option)
squeue # to see the currently running/waiting jobs in slurm
# (additional "-l" option may also be useful)
sbatch Script.sh # to submit a script (example below) to the slurm.
srun <command> # to submit a command to Slurm. Same options as in 'sbatch' can be used.
salloc # to allocate computing nodes. Use for interactive runs.
scancel job_id # to cancel slurm job, job id is the numeric id, seen by the squeue.
Advanced basic commands:
sinfo -N -l # list nodes, state, resources (#CPUs, memory per node, ...), etc.
sshare -a # to list shares of associations to a cluster
sprio -l # to view the factors that comprise a job's scheduling priority
# add '-u <username>' for filtering user
Show information for specific cluster
By default, any of the above commands shows information of the local cluster which is *merlin6.
If you want to see the same information for merlin5 you have to add the parameter --clusters=merlin5.
If you want to see both clusters at the same time, add the option --federation.
Examples:
sinfo # 'sinfo' local cluster which is 'merlin6'
sinfo --clusters=merlin5 # 'sinfo' non-local cluster 'merlin5'
sinfo --federation # 'sinfo' all clusters which are 'merlin5' & 'merlin6'
squeue # 'squeue' local cluster which is 'merlin6'
squeue --clusters=merlin5 # 'squeue' non-local cluster 'merlin5'
squeue --federation # 'squeue' all clusters which are 'merlin5' & 'merlin6'
