Jean Zay: Slurm commands

Jobs are managed on all the nodes by the software Slurm .

To submit a submission script:
```
 $ sbatch script.slurm
```
To monitor jobs which are waiting or in execution:
```
 $ squeue -u $USER
```
This command displays information in the following form:
```
JOBID  PARTITION  NAME  USER  ST   TIME  NODES  NODELIST(REASON)   
  235  part_name  test   abc   R  00:02      1  r6i3n1 
```
Where
JOBID: Job identifier
PARTITION: Partition used
NAME: Job name
USER: User name of job owner
ST: Status of job execution ( R=running, PD=pending, CG=completing )
TIME: Elapsed time
NODES: Number of nodes used
NODELIST: List of nodes used

To obtain complete information about a job (allocated resources and execution status):
```
 $ scontrol show job $JOBID 
```
To cancel an execution:
```
 $ scancel $JOBID 
```

Comments

A complete reference table of Slurm commands is available here .

In case of a problem on the machine, the SLURM default configuration is such that the running jobs are automatically restarted from scratch. If you want to avoid this behavior, you should use the --no-requeue option in the submission process, that is, submit your job doing
```
 $ sbatch --no-requeue script.slurm 
```
or add the line
```
 $SBATCH --no-requeue 
```
in your submission script.
