Check our FAQs! Maybe someone asked a similar question before.


For quick questions, our Rocket.Chat channel #hpc-users is the best option. We will try to react promptly, but sometimes we may ask you to open a ticket instead.

The GWDG Support Ticket System

Write an email to In the body:

  • State your user id ($USER).
  • If you have a problem with your jobs, always
    • include the job ID and
    • the complete standard output and error (-o/-e <file>).
  • If you have a lot of failed jobs, send at least two outputs. You can also list the job IDs of all failed jobs to help us even more with understanding your problem.
  • If you do not mind us looking at your files, please state this in your request. You can limit your permission to specific directories or files.
  • Please open a new ticket for each issue. It is easier for us to merge two tickets if necessary than to split them up.
