Copy Node

Copy nodes are reserved for transfering data to or from a cluster. They usually offer a better connection than other nodes and minimize the disturbance of other users on the system. Depending on the facility, software installed on these nodes may differ from other ones due to their restricted use case, though not every facility chooses to install a designated copy node at all. As an alternative login node may be used to move data between systems.

Frontend Node

Synonym for login node.

Login Node

Login nodes are reserved for connecting to the cluster of a facility. Most of the time they can also be used for testing and performing interactive tasks (e.g. the analysis of previously collected application profiles). These test runs should generally not exceed execution times of just a few minutes and may only be used to verify that your software is running correctly on the system and its environment before submitting batch jobs to the batch system.
