Description

This course addresses hybrid programming by combining OpenMP and MPI, as well as more advanced topics in MPI. Also, parallel I/O is discussed and exemplified in the course. The course consists of lectures and hands-on exercises.

Learning outcome

After the course the participants should have an idea about more advanced techniques and best practices in parallel programming, and on how to scale up parallel applications and optimize them to different platforms.

Prerequisites

The PTC course Introduction to Parallel Programming or similar background knowledge together with fluency in Fortran and/or C programming languages will be assumed.
