Resources
Textbook
Using OpenMP, by: Barbara Chapman, Gabriele Jost and Ruud van der Pas, MIT press, Cambridge, Mass, 2008
This book describes the traditional and for many scientific codes most important concepts of the OpenMP API. The discussion includes performance considerations and common coding mistakes. The book is based on the OpenMP standard 2.5.
Tutorials
Blaise Barney provides a tutorial on the Lawrence Livermore National Laboratory's webpage
Tim Mattson from Intel created a video tutorial: Introduction to OpenMP. The tutorial is freely available on youtube. This tutorial also discusses more recent concepts such as the OpenMP task construct.
Standard Specifications
The most recent and earlier versions of the OpenMP standard is available from the OpenMP ARB's website. Starting with OpenMP 4.0 the examples, explaining some of the constructs in-depth, are no longer part of the actual standard document but are available as a separate document.
