Description
The course includes topics on code optimization for x86 platforms and
efficient code parallelization using OpenMP threading. Advanced aspects
of threading and optimization, such as new features of OpenMP 4.0, will
be covered during the course. Some performance aspects of MPI will also be discussed.
