## 2017/18, winter semester:

Parallel matrix computations

**Charles University, Prague.**

The goal of this course is to introduce parallel processing of basic computational cores
that can be encountered in mathematical modeling as well as in scientific computing in general.
These cores include, for example, basic operations with dense and sparse matrices and parallel
preconditioning of Krylov space methods.
The course includes also elementary introduction into multigrid (not in the text at this moment)
and domain decomposition methods.
