Standard
Documents
The setting copy of our standard documents is available here. The documents 1, 2 and 3 are used in this course. Each document is reduced by a factor of 0.707, i.e., two pages of the original standard document is printed on one paper page.

Programming Models
Some links to the HLRS web pages on programming models:
MPI
OpenMP
Parallel Programming Models
Services of the Department Parallel Computing and the Working Group Technical and Scientific Computing

Production Procedure
The ONLINE version of this workshop was developed in the framework of 100-online.
Poster 1 and Poster 2 give a first survey of this project.
An overview on the production procedure of the online material can be found here.
An overview of this 100-online project can be found here.

Used Web Tools
The slides were produced with PowerPoint from Microsoft.
The audio .wav files were handled with Acoustica 2.21 from Acon AS.
The .wav files were transformed into .rm files the free RealProcucer Basic.
To combine the slides with the audio information, we used the web tool RUS Presenter. It was developed at the HLRS and is based on the results of
Florian Hermle, Konzeption und Realisierung einer Web-basierten Lernapplikation am Beispiel einer Vorlesung des IAS, Studienarbeit,
at IAS, tutor was Jens Konnertz.
