Introduction to HPC-Cluster

Published: 16 Feb 2022 by HPC Team Freiburg

The, University of Stuttgart is pleased to announce its web seminar for bwHPC users.

Title: Introduction to HPC-Cluster

Date: 22.03.2022

Topic: Introduction to HPC-Cluster - bwUniCluster 2.0 (Web Seminar)

Lecturer: Darko Milakovic (HLRS)



High Performance Computing (HPC) means achieving high and highest computing performance. Special HPC clusters and supercomputers are used for this purpose. To achieve maximum performance, all the components involved must be planned and coordinated and operated with each other. The course will give insight into the need for supercomputers and teach the basic structure of a microprocessor​ and multicore processor (x86_64)​ as well as the different aspects of of shared memory CPU-nodes​ and distributed memory system​s. In addition, the course will give an introduction of the bwUniCluster 2.0, including the connection, authentication, batch system, workspaces, module files, visualization, data transfer, file systems and interactive jobs.


  • Why HPC-Cluster / Cluster Computing?​
  • System Architecture​
  • Compute Nodes with Multiple Processors​
  • Coffee Break
  • Cluster Basics
  • Coffee Break
  • Hands On / Live Demo on bwUniCluster 2.0​ (1)
  • Coffee Break
  • Digression: Use Bash in Jupyter Notebooks on bwUniCluster 2.0 (Live Demo)

After this course, participants will…

  • understand the benefits of HPC clusters
  • know the basics about system architecture
  • have gained knowledge about the difference of shared memory CPU-nodes​ and distributed memory system​s
  • be able to properly connect to the bwUniCluster 2.0
  • know about the file systems, environment module system, data transfer on the bwUniCluster 2.0
  • have a detailed understanding about the most important commands (of the batch system) on the bwUniCluster 2.0

Prerequisites: The background of Linux as well as the most important concepts and tools of Linux should be known, e.g.

  • Shell and shell commands (→safe use of the command line),
  • secure shell,
  • the handling of files and scripts,
  • the structure of the system,
  • the user and rights management and
  • creating simple batch scripts with an editor like nano, vi or emacs.

FIDO2 and TOTP Token as a Second Factor for bwHPC and NEMO2

The use of a second factor to secure logins to services is becoming increasingly mandatory. bwHPC currently uses time-based one-time passwords (TOTP) or Yubico OTP as a second factor for SSH logins. We have looked at some hardware security tokens for bwIDM/bwHPC that can be used instead of a mobile phone.

News on NEMO2 Procurement

The initial partition of NEMO2, consisting of around 140 Milan nodes and 1000 terabytes (one petabyte) of high-speed storage space, has been ordered. A tender for a GPU partition and a second CPU partition will be opened in early 2024.
