Shared memory parallelization with OpenMP @ VSC Vienna

The focus of this 2 days course is on shared memory parallelization with OpenMP for dual-core, multi-core, shared memory, and ccNUMA platforms. This course teaches OpenMP starting from a beginners level. Hands-on sessions (in C and Fortran) will allow users to immediately test and understand the OpenMP directives, environment variables, and library routines. Race-condition debugging tools are also presented.

This course is a PRACE training event. It is organized by the VSC Research Center, TU Wien, in cooperation with the High-Performance Computing-Center Stuttgart (HLRS). This course has been originally developed by Rolf Rabenseifner (HLRS).
