Workshop on using the Magnolia HPC cluster.

When:  July 18, 2023 10 am — 12 pm
Where:  PSRC 105
Watch Recording:  USM SharePoint Video Link.


Description

This workshop is intended for users that have used the cluster and wish to learn how to use it more efficiently. Topics include the following:

  • Introduction to the Magnolia High Performance Computing (HPC) cluster
  • HPC workflow
  • Quick review of Linux shell commands
  • Using pre-installed programs and software (Linux Environment Modules)
  • Python
  • Compiling C/C++ programs
  • How serial (single threaded) programs can take advantage of HPC Clusters
Note
This workshop is focused on how to use an HPC cluster, not how to use the individual software packages discussed. For example, during the Python topic, ways to use python on the cluster will be explored, not how to code in the Python programming language.

Requirements

Prior knowledge of the Magnolia HPC cluster will be useful, but is not required.

Bring a laptop that can connect to the Magnolia HPC Cluster (see the Check connection to the cluster section below).

In-person and Virtual

In-person attendance is preferred, but for those who are not at the Hattiesburg Campus a Zoom link will be posted in the header of this page.

Registration

Please fill out the registration form to reserve a seat.

Direct link to the registration form: https://redcap.usm.edu/surveys/?s=33D4LKAWY8NLX9X3

Check connection to the cluster

Please check that you can connect to the cluster before attending the workshop. Connecting to the cluster is typically done using ssh (see Connecting/Login for more details). If you are using Linux or OSX, ssh is used from the terminal. Type the command shown below to check the host key fingerprint. Do not enter any passwords. Instead, cancel by typing Control+C. For Windows users, install an ssh client like PuTTY (https://www.putty.org) and follow the directions given in the following link: Windows Specific Directions

user $ssh -o VisualHostKey=yes check@magnolia.usm.edu
Host key fingerprint is SHA256:glQIZZKlsAwf3QJNNDQSxFpRzE2rKs4GfxByO6ZBzis

Make sure that the host key fingerprint (In this case: SHA256:glQIZZKlsAwf3QJNNDQSxFpRzE2rKs4GfxByO6ZBzis) matches one of the fingerprints given in the list of SSH Fingerprint for Magnolia.

If you have any questions, please contact Brian G. Olson.
