Learning How to program on HPC cluster (part III: Python)

Monday 14 Nov 2022, 09:00 → 17:00 Europe/Brussels

CYCLOTRON E349 (Louvain-La-Neuve)

Python is a scripting language used in many scientific software. IN this session, we will cover python from the basic of the language up to the advanced usage on HPC, going trough a lecture on how to write good object oriented code with Python.

1 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.

2 Python as an Object Oriented Language

The point of this lecture is to explain the concept of object oriented programming and using python to present the various concept and advantages.
Contents: Data structure Class Object/Instance Inheritance	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 are using Python for science

3 Efficient use of Python on the clusters

The use of Python for scientific computing is rising thanks to modules such as numpy, scipy and mathplotlib. This session explores the efficient uses of Python in that context for situations where numpy and co. are of less use. It assumes a working knowledge of Python.
Contents: Installing libraries Numpy Scipy Matplotlib MPI python Multithreading Compiling	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.) Working knowledge of Python Type: Hands-on Target audience: Confirmed Python user Must: This session is a must-have for anyone thinks Python is slow.
