# Overview on how to use Mogon

There are some requirements that have to met before you can start using Mogon. You'll find more information about it here.

Enroll for the Mogon-Introductory-course as soon as possible - especially if you don't have experience in working in a HPC environment.

Mogon is a Linux-based cluster currently running Scientific-Linux/CentOS and LSF as batch-system. There are two 2 login nodes for all users except for the ETAP users - they have their own 4 login nodes.

Calculations are to be submitted as jobs. This means jobs are not to be run on login-nodes. Processes run directly on these nodes should be limited to tasks such as editing, data transfer and management, data analysis, compiling codes and debugging, as long as it is not resource intensive (memory, cpu, network and/or i/o). Any resource intensive work must be run on the compute nodes through the batch system.

Please do not impair the work of other users by cluttering login-nodes.

Therefore: Any process that is consuming extensive resources on a login-node may be killed, especially when it begins to impact other users on that node. If a process is creating significant problems on the system, the process will be killed immediately and the user will be contacted via email.

## Avoiding the Batch System

While is is not (easily) possible to calculate on compute hosts without using the batch system: It is prohibited. Any computational process not associated with a corresponding job will be killed.
