How to prepare, run and manage jobs?

In order to run batch jobs or interactive jobs, you need to log in to the login node of your housed system. If your housed system does not have it's own login node, you may use the CoolMUC-4 login node:

ssh -Y userID@cool.hpc.lrz.de

Please consult Access and Login to the Linux-Cluster for further details on:

the login procedure,
the ssh documentation, e.g. policies,
two-factor authentication.

Please consult the Linux Cluster documentation and subpages for

examples of batch job scripts for serial or parallel jobs (e.g., shared-memory or MPI jobs),
job submission procedure,
Slurm commands to manage jobs.

You may need to adapt the examples according to your needs and the requirements of your housed system!

Please also consider our policies and rules!
