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)

Web: https://training.bwhpc.de/goto.php?target=crs_664&client_id=BWHPC

Abstract

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 systems. 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.

Agenda

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 systems
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.

The course language is German but slides are in English.
It is recommended to try the code/command examples yourself interactively by using your own computer.
With a successful registration for the course, the participants get access to the content on the bwHPC-Ilias
The participants need to have access to the bwUniCluster 2.0, for this they need the bwUniCluster entitlement:
- Obtainment of bwUniCluster entitlement: https://training.bwhpc.de/goto.php?target=pg_5102_311&client_id=BWHPC
- Further information on bwHPC-Wiki: https://wiki.bwhpc.de/e/BwUniCluster_2.0_User_Access
Due to the limited number of free spots (35) early registration is recommended.
