Learning how to use HPC infrastructure (part I)

Monday 17 Oct 2022, 09:00 → 17:00 Europe/Brussels

MERCATOR 04 (Louvain-La-Neuve)

You need to use an HPC cluster, and you do not know how to connect and/or how to use Unix? Then this training is for you. We will start by a broad introduction on the various topic that can be useful for you on the HPC environment and then explain how to correctly/efficiently setup your connection to work efficiently (ssh, file transfer/syncronization/...) and finally we give a tutorial on the UNIX command line interface to master file operation.
Contents: Introduction to HPC SSH on windows SSH on Mac/Unix Unix	Prerequisite: None
	Type: Lecture in person Target audience: Rookie Must: The content is a requirement for all others session

1 Introduction to high-performance computing

This first session introduces to the field of high performance computing and presents the whole training offer.
Contents: Introduction to cluster computing: strengths and weaknesses Presentation of the CÉCI clusters and collborators, and Tier-1 Presentation of the training sessions Presentation of the account creation process	No prerequisite. Prerequisite for: all the other sessions.  Type: Lecture Target audience: Everyone Must: This session is mandatory.

Speaker: Frédéric Wautelet (University of Namur)

2 Connecting with SSH from Windows and Linux on CECI clusters (1)

SSH is the protocol used to connect to the clusters. This session presents the complete use of the tools to make access to the clusters easy (without being harrassed by passphrase requests, coping with firewalls in a transparent manner, transferring files from one cluster to another, etc.)
Contents: SSH client usage and common errors SSH keys, passphrases and agents SSH configuration file Passphrase managers Tunnels, proxies and (pseudo-)VPNs SSH-based file transfer (SCP, rsync, Unison, SSHFS)	Prerequisite: Being familiar with a text editor  Mastering the Linux command line and the GNU utilities (mkdir, cp, scp, etc.) Prerequisite for: all the other sessions   Type: Hands-on,  Target audience: Everyone Must: This session is mandatory.

Speakers: Juan Cabrera (UNamur/PTCI), Olivier Mattelaer (UCLouvain/CISM)

4 Introduction to linux and the command line

Often, the workflow for researchers is to acquire a piece of software, and either modify it, or wrap it in scripts, or simply install it on the clusters, or all of that at the same time, on many clusters. This session will introduce to the tools that can make this whole process easier.
Contents: Programming paradigms Types of languages and the choice of the language. Tools for deploying software  The programmer's toolkit  Writing comments and elements of style	Prerequisite: Being familiar with a text editor  Mastering the Linux command line and the GNU utilities (mkdir, cp, scp, etc.)
Type: Lecture Target audience: Rookie programmers Must: This session is a nice-to-have.

Speaker: Bernard Van Renterghem (UCL CISM)
