Overview
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.
Content Levels: Beginners = 6:00h (50%) + Intermediate = 4:00h (33%) + Advanced = 2:00h (17%)
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).

Course Format: |
This course will be delivered as a LIVE ONLINE COURSE (using Zoom) for remote participation. |
|---|---|
|
Prerequisites: |
For the hands-on sessions you should be able to program in either C/C++ or Fortran and if you do the exercises on the VSC you should know how to work on the Unix/Linux command line. |
|
Hands-on Labs: |
Participants can choose between using their own laptops or any system they have access to that provides an OpenMP enabled compiler for their preferred programming language C/C++ or Fortran. Alternatively, participants can ask for a training user account at the VSC for the duration of the course. Accepted participants will be contacted a few days before the course and asked to do a short PRE-ASSIGNMENT that has to be completed before the course starts. |
| Language: | English |
