Lecture with practical project part (VU), attendendance is mandatory and really recommended. Lectures by Jesper Larsson Träff.
Lectures on Mondays 15.15 - 17.00 in lecture hall "Informatikhörsaal". Additional slots for exercises Tuesdays, 15:15 - 17:00 (Informatikhörsaal). See TISS and TUWEL.


The aim of this lecture is to given an introduction to parallel computing on different types of dedicated, parallel computing systems. This includes basic concepts on how to achieve and estimate parallel performance, and practical exposure to some of the most common, current programming models, frameworks and paradigms.
Contents: Basic concepts, history, motivation. Shared-memory parallel computing, concrete languages: pthreads, OpenMP (and Cilk). Distributed memory computing, concrete interface: MPI. New languages, other paradigms.
