Computational clusters
Jakl, Ondřej
The contribution deals with clusters of workstations in the context of their employment in parallel processing. It focuses on the nowadays very popular systems based on personal computers (so called Beowulf) and using the Linux operating system. On example of parallel solvers we demostrate that their performance is comparable with that of the much more expensive commercial parallel systems.

Parallelization on symmetric multiprocessors
Jakl, Ondřej
The contribution introduces into the programming of demanding applications on multiprocessors with shared memory. It provides an overview of the parallelization alternatives on this architecture and focuses on those which are based on multithreading. The most important tool, recently established standard OpenMP, is shown on an example.
