Node cn01 is the cluster frontend, that can be accessed via hpc-uni.uni-tuebingen.de, which is an alias for u-003-scfe02.uni-tuebingen.de. Only this node is accessible directly and must be used for submitting jobs.
The cluster management unit (CMU) is named cmu00.uni-tuebingen.de, which is an alias for u-003-scmu00.uni-tuebingen.de. The CMU can not be accessed by normal users and is needed to perform administrative tasks. It is available over a web frontend.
