Description

Do you need to use an HPC cluster, but you do not know how to connect and/or how to use Unix? Then this training is for you.

We will start the day with a broad introduction to the various topics that can be useful for you regarding 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 Linux/UNIX command line interface to interact with the clusters.

  • Introduction to high-performance computing
  • Connecting with SSH from Windows and Linux on CECI clusters
  •  Introduction to linux and the command line

Prerequisite:

      Connecting with SSH from Windows and Linux on CECI clusters 2h

      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)

      Introduction to linux and the command line 2h

      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)
