Tuesday 17 Oct 2023, 09:30 → 18:15 Europe/Brussels

Maxwell/Shannon (first floor) (Louvain-La-Neuve)

We will continue to learn the fundamental tool needed to use a cluster. We will cover how to choose/activate the (version) of software that you need, how to edit a file on any HPC cluster, how to script simple tasks.
Contents: Choosing and activating software with system modules on CECI clusters Writing and editing text files with Vim Bash scripting	Prerequisite: Being able to use SSH with private keys
	Type: Lecture Hands-on Target audience: Rookie Must: This session is a must-have for anyone.

09:30 → 11:00 Choosing and activating software with system modules on CECI clusters

Software installed on the clusters is organised and managed with environment modules that allow choosing a specific version of a software package compiled with a given compiler, linked to chosen libraries, etc. This session explains how modules are used on the clusters.
Contents: The installed software The modules command What is Easybuild What are the different toolchains how to install software by yourself	Prerequisite: Being able to use SSH with private keys  Being familiar with a text editor  Mastering the Linux command line and the GNU utilities (mkdir, cp, scp, etc.)
