Training course "Directive-based GPU programming with OpenACC"

(Course no. 802020 in the training programme 2020 of Forschungszentrum Jülich)

26 Oct 2020 09:00
27 Oct 2020 17:00
Jülich Supercomputing Centre, Ausbildungsraum 1, building 16.3, room 213a

Target audience:
Scientists who want to use GPU systems with OpenACC

GPU-accelerated computing drives current scientific research. Writing fast numeric algorithms for GPUs offers high application performance by offloading compute-intensive portions of the code to the GPU. The course will cover basic aspects of GPU architectures and programming. Focus is on the usage of the directive-based OpenACC programming model which allows for portable application development. Examples of increasing complexity will be used to demonstrate optimization and tuning of scientific applications.

Topics covered will include:

  • Introduction to GPU/Parallel computing
  • Programming model OpenACC
  • Interoperability of OpenACC with GPU libraries (like cuBLAS and cuFFT) and CUDA
  • Multi-GPU Programming with MPI and OpenACC
  • Tools for debugging and profiling
  • Performance optimization

The course consists of lectures and interactive hands-on sessions in C or Fortran (the attendee’s choice).

Some knowledge about Linux, e.g. make, command line editor, Linux shell (see for instance this overview), experience in C
This course is given in English.

Additional Information

JSC Events - Measures Regarding the Coronavirus Pandemic

Due to the preventive measures at Forschungszentrum Jülich regarding the spreading of the Coronavirus, all JSC courses and events in March and April were cancelled. They will be rescheduled later.

For the time being and with the rapidly changing situation in mind, JSC cannot foresee whether courses and events in May and later can take place as scheduled as face-2-face events. Seminar talks might be streamed as video conferences, courses might be postponed or partly given as webinars. We still take registrations for the upcoming courses. All participants who registered for courses so far will be notified by e-mail after the regular registration deadline whether and how the courses will be held.

Please check regularly with the webpage whether upcoming events will take place at all or be streamed as a video conference.
