Cluster usage
-------------
The cluster is managed by a job submission system (called SLURM). Users submit jobs to a queue in the scheduling system, which then executes them on compute nodes in the cluster. The allocation of jobs to resources is managed by SLURM and is based on the fair usage, requested resources, available resources, queue and account priorities.


Submitting jobs
^^^^^^^^^^^^^^^
To submit a job to the cluster, use the ``sbatch`` command:

.. code:: bash

    sbatch myjob.slr


Monitoring jobs
^^^^^^^^^^^^^^^
After submitting jobs to the cluster, you can monitor your jobs using:

.. code:: bash

   squeue

This command lists all jobs on the cluster, including their job ID, the partition to which they have been submitted, the job name and user. It also lists the status of the job and the time it has been running. The reason why the job is not running may also be shown for jobs in the queue.


Partition information
^^^^^^^^^^^^^^^^^^^^^
To obtain information about the partitions on the cluster, use the command:

.. code:: bash

   sinfo

For example, the output might look similar to:

.. code:: bash

   $ sinfo
