Monthly HPC Café and Beginner’s Introduction

Monthly HPC Café

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.

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.

If possible, the HPC Café will be held in hybrid mode; if you want to attend in person, free coffee and cake awaits!

 

Next HPC Café: Tuesday, January 14, 2025

Speaker: Dr. Christian Meesters, Johannes Gutenberg University Mainz

Location (hybrid event): Seminar room 2.049 (RRZE, Martensstraße 1, 91058 Erlangen) and Zoom: https://go-nhr.de/hpc-cafe

Beginner’s Introduction “HPC in a nutshell”

Each month, the two days after the HPC Café are specifically dedicated to new users and HPC beginners.

On Wednesday NHR@FAU offers a one-hour General Introduction (online) on using the HPC systems, including an overview of HPC clusters, how to connect to the systems, how to use the batch system, and more. This well-received format aims at reducing the entry barrier for new and inexperienced users. The content is continuously updated to reflect recent changes in NHR@FAU systems and access rules.

A one-hour Introduction for AI Users (online) on Thursday is aimed at newcomers who plan to run AI workloads on the NHR@FAU systems. The following topics are planned: File handling for AI workloads, fast storage options, setting up python environments for AI, setting up containers with Apptainer.

Next introduction for beginners (online):

It is highly recommended to visit the general introduction as a preparation for the introduction for AI users.
