Description

This workshop addresses more advanced topics and techniques in parallel programming. More advanced topics in message-passing interface (MPI); shared-memory parallelization techniques (with OpenMP) combined with MPI; parallel I/O techniques; as well as parallel tools and numerical libraries are discussed and exemplified.

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 applications and optimize them to different platforms.Prerequisites

The PATC course Introduction to Parallel Programming or equivalent background knowledge together with fluency in Fortran 95 and/or C programming languages will be assumed.
