GöHPCoffee
The GöHPCoffee is a bi-weekly meeting on Wednesdays at 11:00 to give a place for a free and informal meeting between users and staff. These meetings are open to anyone, regardless of your expertise on HPC, we welcome everyone. Our aim with these events is to support the HPC user community, in particular
- improve communication between users and admins,
- support networking between the users,
- help you with issues and answer your questions,
- and share our plans and get your feedback.
You can just enjoy a coffee with us. Also, if you have questions and issues, that seem too small, too big, or too complicated to put into a ticket, come join us. We will gladly
- help with Linux questions,
- give you scripting advice,
- help you set up simple or complicated Slurm scripts,
- give hints about performance improvements,
- debug your connection troubles,
- and so on.
Each event aims to have a short focus session for 5-10 minutes in the beginning. The topics can be about anything from interesting use cases, challenging issues, to new software features or workflow engines. Or even if you just want to show off a cool (job-)script. Hence, we invite everyone to contribute to these topics. If you want to give such a small presentation or request one about a specific topic, please let us know.
The rest of the meeting is open to discussions, problem-solving, and well, coffee. You will find a list of sessions with their discussed topics and slides in the table below. If you have any further questions, please reach out to our community manager Alexander Goldmann.
For now, the meetings will take place on BigBlueButton. You are also invited to join our #hpc-users channel on our RocketChat Server.
Next session: 2024-05-15
