27 - 28 April 2023, 09:00 - 16:30 CEST
Course for academia and industry
Organised by VSC Research Center (TU Wien) in cooperation with the High-Performance Computing-Center Stuttgart (HLRS). Funded by EuroCC and EuroCC Austria.
Language: English
Location: hybrid (online - Zoom or FH Internet-Raum FH1 at TU Wien)
Price: free
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%)
Note, an additional course on Distributed memory parallelization with the Message Passing Interface (MPI) takes place on the previous three days, registration for both courses can be done on the same registration form.

Course format
This course will be delivered as an HYBRID COURSE, i.e., you can choose either in-person attendance onsite at TU Wien or online participation via Zoom.
If you are planning to travel to Vienna for in-person attendance, we strongly recommend to choose travel options and hotels with the possibility to cancel (even close to the event) because we might be forced to deliver the course entirely online if Covid strikes back.
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),
TBD (tutors; VSC Research Center, TU Wien)
