On clusters and distributed memory architectures, parallel programming with the Message Passing Interface (MPI) is the dominating programming model. This 4 half-days course teaches parallel programming with MPI starting from a beginners level. Hands-on sessions (in C, Fortran, and Python) allow to immediately test and understand the basic constructs of the Message Passing Interface (MPI).

Target audience

Course for academia, industry, and public administration.

Course format

This course will be delivered as a LIVE ONLINE COURSE (using Zoom).

Hands-on labs

All participants will get a temporary user account on the VSC to do the hands-on labs.

Alternatively, it is possible to do the hands-on labs on your own laptop or on any system you have access to that provides a C/C++ or Fortran compiler, or Python+numpy+mpi4py, and a recent MPI library.

Accepted participants will be contacted a few days before the course and asked to do a short PRE-ASSIGNMENT that has to be completed before the course starts.
