Short description: Note: Please send us an e-mail; we will contact you as soon as possible.

The HPC Café complements our established contact channels and training offerings. Every second Tuesday of the month this is an opportunity to get to know each other.

We always start with a short Q&A session, where you can ask and discuss anything HPC related, from running job scripts to performance issues.
Every month, we will also focus on a specific topic, either as a short talk or a discussion. These can include, e.g., advanced usage, workflow optimizations, or application-specific issues.

A separate event on the day after the HPC Café is especially dedicated to new users and HPC beginners. Each month, we offer a short introduction on using the HPC systems at RRZE, including an overview of HPC clusters, how to connect to the systems, how to use the batch system, and more.

The HPC Café is also an informal platform to give feedback or talk about general requests. We look forward to meeting you and hope for lively participation.

Good news: There will be free coffee and cake again after more than two years of abstinence!

Next event: Tuesday, February 14, 2023, 4:00 p.m.

Focus topic: The KONWIHR program: overview and funding opportunities
