Description

Python programming language has become popular in scientific computing due to many benefits it offers for fast code development. Unfortunately, the performance of pure Python programs is often sub-optimal, but fortunately this can be easily remedied. In this course we teach various ways to optimise and parallelise Python programs. Among the topics are performance analysis, efficient use of NumPy arrays, extending Python with more efficient languages (Cython), and parallel computing with  message passing (mpi4py) approach.

Learning outcome

After the course participants are able to

  • analyse performance of Python program and use NumPy more efficiently
  • optimize Python programs with Cython
  • utilize external libraries in Python programs
  • write simple parallel programs with Python

Prerequisites

Participants need some experience in Python programming, but expertise is not required. One should be familiar with

  • Python syntax
  • Basic builtin datastructures (lists, tuples, dictionaries)
  • Control structures (if-else, for, while)
  • Writing functions and modules

Some previous experience on NumPy will be useful, but not strictly required.
