Description

The course includes topics on code optimization for x86 platforms and efficient code parallelisation using OpenMP threading. Advanced aspects of threading and optimization, such as new features in OpenMP 4.5, will be covered during the course. Some performance aspects of hybrid MPI+OpenMP programs will also be discussed.
