	1) Submit a slurm job, or start an interactive job on a node. ~~Taking node201 as an example:~~		* Submit a slurm job, or start an interactive job on a node.

	sinteractive ~~--partition=main --nodelist=node201~~		sinteractive

	~~2) In~~ your ~~local OS~~, ~~set up a port tunnel connection (For example using port 2222):~~		* Check on which node this job has landed

	~~5) VSCode connection: in the VSCode GUI -> Open a remote Window -> Connect to Host...,~~		Please be aware that once the slurm job finishes, the connection will be lost and your running processes will be killed.
	~~choose "localhost". After a few seconds, the VSCode is connected to the node201.~~		Besides that, you are limited to the amount of RAM that you requested.

	Please be aware that once the slurm job finishes, the connection will be lost.
