-It is therefore not allowed to run processes that take a significant amount of memory or CPU power. We have a short queue available if you quickly want to test something.

-The filesystems /data, /home, and /scratch are shared. Updating the metadata on a large number of files on these filesystems leads to a degraded performance for other users and is therefore not allowed. This can happen, for example, by running the Unix command ''touch'' automatically on a large number of files.+
  
-We also might contact you if you do other things that adversely affect the performance of the cluster for other users.+Please be aware that the cluster is used by many researchers. We may therefore contact you if you do things that adversely affect the performance of the cluster for other users, in order to try to help you find ways to improve your workflow.
