Description

This course is an introduction to OpenACC and OpenMP to target GPU. These programming models are based on programmers inserting hints into their C/C++ or Fortran programs on how the code can be parallelized. OpenMP, was initially designed for shared-memory system with CPU but has recently been extended to target heterogeneous systems with accelerators like GPU.  OpenACC, on the other end, was designed from the start to target accelerators.

Contents: Basics of OpenMP offloading and OpenACC Compute and worksharing constructs Data management Asynchronous execution and synchronization

Prerequisite: Being able to use SSH with private keys  Being familiar with a text editor  Mastering the Linux command line and the GNU utilities (mkdir, cp, scp, etc.) Basic knowledge of C/C++ or Fortran Type: Hands-on Target audience: Rookie programmer Must: This session is a nice-to-have for those who need to develop highly scientific software.
