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:
```bash
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.
sview # X interface for managing jobs and track job run information.
seff # Calculates the efficiency of a job
sjstat # List attributes of jobs under the SLURM control
sacct # Show job accounting, useful for checking details of finished jobs.
```
---
## Advanced basic commands:
```bash
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:
```bash
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'
```
