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 preconditioning of Krylov space methods. The course includes also elementary introduction into multigrid and domain decomposition methods.
Aim of the course -
Last update: prof. Ing. Miroslav Tůma, CSc. (22.02.2018)

The main goal of the course is to understand basic ideas related to computational tools on contemporary and inevitably parallel computer architectures.

The focus is to discuss what should a computational mathematician consider to get

basic computational schemes efficient in parallel computational environment.

The goal is also to learn basic practical experience with parallel matrix computations on unix-like

systems using Python.

Needed to get credits:

• students will independently prepare a parallel program based on theoretical examples discussed during lectures. The lectures can be also in the online distant form.

Lectures and tutorials in a lecture hall. A possible variant it to use an online distant lectures and tutorials.

Requirements to the exam -
Last update: prof. Ing. Miroslav Tůma, CSc. (28.04.2020)

Examination according to the syllabus.

• students will be asked one thematically general question

• students will have enough time to prepare their answer

• examinor can pose subquestion related to the main question

• all of this can be replaced by an online distant examination

Syllabus -

1. Computational models for parallel architectures.

2. Basic parallel operations with dense and sparse matrices.

3. Preconditioning and preconditioned Krylov space methods.

4. Domain decomposition and multigrid methods.

5. Parallelization of direct methods for sparse matrices.

Entry requirements -
Last update: prof. Ing. Miroslav Tůma, CSc. (16.05.2018)

As a preliminary we assume to have basic knowledge of linear algebra as, for example, from the course

NMAG101. Some graph theory knowledge is an advantage but not necessity.
