Learning How to program on HPC cluster (part II: C, Python)

Wednesday 6 Nov 2024, 09:30 → 16:45 Europe/Brussels

SCES A.04B (Louvain-La-Neuve)

In this session we will cover the basics of some of the most common programming languages for HPC (syntax and basic concept)
Contents: Introduction to programation with C language Debugging and profiling scientific code, and commercial optimized libraries 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 programming 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 C++

Introduction to object-oriented programming, classes and templates in C++. Learn useful design patterns that will help you design the architecture of your project.

Content:
- From C to C++
- What is a class ? What is an object ?
- Template programming
- Inheritance, abstract classes and interfaces
- Some more design patterns
- Good practices
- Some pointers to libraries and projects of interest

Prerequisite:
- Being familiar with a text editor
- Being familiar with programming (at least beginner level)
- Understanding what a compiler is

Target audience: Rookie programmer

Speaker: Nicolas Potvin (ULB département informatique)

3 Introduction to Python

Python is a programming language that can be used both for scientific computing (as a replacement for Fortran or C/C++) and for everyday scripting (as a replacement for Bash or Perl), but also to develop full programs with a GUI as well as headless services. It is a very nice tool to include in any scientist's toolbox.
Contents: Language syntax The core modules Installing external modules Writing and distributing modules	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.) Notions of programming Type: Hands-on Target audience: Rookie programmer Must: This session is a nice-to-have for those who do not know Python.

Speaker: Mr Jérôme de Favereau (UCLouvain/IRMP/CP3)
