Online: Advanced Parallel Programming

10.3.2021 09:00 - 12.3.2021 16:00

Online event

This online course addresses hybrid programming by combining OpenMP and MPI, as well as more advanced topics in MPI (communication topologies, user-defined data type, and one-side-communications). Also, parallel I/O is discussed and exemplified in the course. The course consists of lectures and hands-on exercises on Puhti. The participants will be informed on connections details before the course.

Learning outcome

After the course the participants should be able to know how to combine MPI and OpenMP programming models to use full nodes efficiently, how to define its own sub-communicators in order to take advantage of network topology or special data patterns, define its own custom datatypes, and know how to efficiently save data in parallel using MPI-IO or HDF5, as well as understand the basics of the one-sided MPI communication.

Prerequisites and content level

In order to take the course the participant should be fluent in FORTRAN and/or C programming languages and have taken the PTC course Introduction to Parallel Computing or have similar background knowledge of MPI and OpenMP.

The content level of the course is broken down as: beginner's - 14%, intermediate - 51%, advanced - 35%, community-targeted content - 0%.
