Connecting to nodes
===================

.. IMPORTANT:: **Login to compute nodes**

    Users are not allowed to login to compute nodes **unless** they have a job running there.

Once you have a job running on a node, you can ssh directly to it and run additional processes, or observe how you application behaves, debug issues, and so on.

.. note::

    Please note that your ssh session will be attached to your running job, and that resources used by that interactive shell will count towards your job's resource limits. So if you start a process using large amounts of memory via ssh while your job is running, you may hit the job's memory limits, which will trigger its termination.
