Learning How to program on HPC cluster (part II: Fortran/C/Julia)

Wednesday 9 Nov 2022, 09:00 → 17:00 Europe/Brussels

MERCATOR B336 (Louvain-La-Neuve)

In this session we will cover the basics of some of the most common language of programation (syntax and basic concept)
Contents: Introduction to C programming language Introduction to JULIA Introduction to structured programming with Fortran	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 programmers Must: This session is a must for anyone who needs to write programs.

1 Introduction to programation with C language

C is a very performant language on which are build C++ but also Python (and many others). Even if this language is now mainly superseeded by C++, it is important to understand the basic of the language if you want to learn C++ and or Cuda programming (for GPU).

Contents: Basic of C programming pointer concept array memory management

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.) Prerequisite for: CUDA programming Type: Hands-on Target audience: Rookie programmer Must: This session is a nice-to-have for those who need to develop fast scientific software.

Speaker: Olivier Mattelaer (UCLouvain/CISM)

2 Introduction to Julia

Julia is a recent (2012) programming language created at the MIT with the aim to provide performance on par with the likes of C and Fortran, with the ease of use of languages like Python and Matlab. The goal of this session is to introduce the key ideas of Julia while giving as many pointers for getting started as possible.

Contents:

• Basics of Julia
• Multiple Dispatch
• Benchmarking
• Parallel Programming

 

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 nice-to-have for those who need to develop fast scientific software.

Speaker: Cédric Simal (Université de Namur)

3 Introduction to structured programming with Fortran

Fortran is the historical language of scientific computing. Many often-used mathematical libraries used nowadays were writen initially in Fortran and have evolved with both the language and the hardware.
Contents: Historical perspective Syntax Printing and formatting Memory management Fortran I/O	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 nice-to-have for those who need to develop fast scientific software.

Speaker: Pierre-Yves Barriat (UCL/ELIC)
