Online Course - Shared memory parallelization with OpenMP

Workshop

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%)

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.

Lecturers:

Lukas Einkemmer, Philipp Gschwandtner, and Martina Prugger (University of Innsbruck),Claudia Blaas-Schenner (VSC Research Center, TU Wien),
Moritz Siegel (tutor; VSC Research Center, TU Wien)

Prices and Eligibility:

This course is a PRACE Training Center (PTC) event. Therefore, the course is open and free of charge for participants from academia and industry from the Member States (MS) of the European Union (EU) and Associated/Other Countries to the Horizon 2020 programme.

Course Material:

The course material will be available at course start.
