### Slurm commander
The **[Slurm Commander (scom)](https://github.com/CLIP-HPC/SlurmCommander/)** it's a simple but very useful open source text-based user interface for
simple and efficient interaction with Slurm. It is originally developed by the CLoud Infrastructure Project (CLIP-HPC). To use it, one can
simply run the following command:
```bash
scom # merlin6 cluster
SLURM_CLUSTERS=merlin5 scom # merlin5 cluster
SLURM_CLUSTERS=gmerlin6 scom # gmerlin6 cluster
scom -h # Help and extra options
```
With this simple interface, users can interact with queued jobs, as well as getting information about past and present jobs:
* Filtering jobs by substring is possible with the `/` key.
* Users can perform multiple actions on their jobs, such like cancelling or requeing a job, SSH to a node with an already running job,
or getting extended details of the job itself.
Also, users can check the status of the cluster, to get statistics and node usage information as well as getting information about node properties.
The interface also provides a few job templates for different use cases (i.e. MPI, OpenMP, Hybrid, single core). Users can modify these templates,
save it locally to the current directory, and submit the job to the cluster.
{{site.data.alerts.note}}Currently, <span style="color:darkblue;">scom</span> does not provide live updated information for the <span style="color:darkorange;">[Job History]</span> tab.
To update Job History information, users have exit the application with the <span style="color:darkorange;">q</span> key. Other tabs are updated every 5 seconds.
On the other hand, the <span style="color:darkorange;">[Job History]</span> tab contains only information for the <b>merlin6</b> CPU cluster only. Future updates will provide information
for other clusters.
