Parallelization with MPI

This course will be delivered as an HYBRID COURSE - on-site at TU Wien or online via Zoom.

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) will allow users to immediately test and understand the basic constructs of the Message Passing Interface (MPI).

This course has been originally developed by Rolf Rabenseifner from the High-Performance Computing-Center Stuttgart (HLRS) and is organized in cooperation with HLRS.
