Learning How to program on HPC cluster (part IV: Tools)

Wednesday 16 Nov 2022, 09:00 → 17:00 Europe/Brussels

MERCATOR B336 (Louvain-La-Neuve)

In this session, we will teach you how to optimise your code, how to maintain it and how to share it with others.
Contents: Introduction to code versioning (git) Debugging and profiling scientific code commercial optimized libraries	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.) Passive knowledge of either C, Fortran, Octave, Python or R
	Type: Hands-on Target audience: Programmers Must: This session is important for programmers who want to optimize/maintain their code.

1 Introduction to code versioning

Code versioning is very important to master, even for non programmers. It allows tracking the changes made to a submission script, a piece of code, a configuration file, or event a dataset and propagate the changes in a consistent and systematic way to all clusters.
Contents: Notions of code versioning Working as a team with code versioning Using git to access code from others Publishing code	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.)
Type: Hands-on Target audience: Rookie programmer Must: This session is a must-have for anyone not familiar with code versioning or git.

Speaker: Olivier Mattelaer (UCLouvain/CISM)

2 Debugging and profiling scientific code, and commercial optimized libraries

When a piece of software does not work the way it is expected to, it needs debugging. Then, when it works, it needs profiling to remove the bottlenecks. This session will also present the standard optimized librairies that will allow you to code faster and more efficiently.
Contents: Debugging principles The GNU debugger (gdb) The Intel debugger Advanced features of Intel Cluster studio the support of MIC architecture (Xeon Phi) the Guided Auto Parallelism the Coarray Fortran support Intel MKL	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.) Passive knowledge of either C, Fortran, Octave, Python or R Working knowledge of C or Fortran Familiarity with OpenMP and MPI
Type: Hands-on Target audience: Programmers Must: This session is important for programmers who want to optimize their code for usage on a cluster.
