The Frontend is the node you connect to remotely. Its primary function is to allow remote access to the calculation clusters by all users and (in limited circumstances) to edit and compile source codes. It must never be used to execute resource-intensive codes, as these will slow down the work of other users and leads to loss of cluster functionality and eventually lead to the blocking of the entire infrastructure.

If an executable must necessarily be tested on the Frontend, the responsible user must actively monitor the job and be sure that it is not active for more than a few seconds.

To execute serial or parallel code, it is necessary to use the Slurm WorkLoad Manager, which will allocate the necessary resources and manage the priority of requests. Below are some of the basic functions and operating instructions for submitting serial and parallel jobs via Slurm; please refer to the official documentation for further information.
