Intro to Open ACC

Sign up or log in to save this to your schedule and see who's attending!

Audience: A bit of C or Fortran experience is helpful, no GPU Computing experience required.


Using OpenACC directives, developers can create high-level applications to execute on modern heterogeneous systems, combining CPUs and accelerators. In this tutorial you will learn about GPUs and how their high performance can be used to accelerate applications by adding simple OpenACC directives to familiar programming languages.

After an introduction to GPU programming, you will write your first OpenACC program to understand the concepts of how directives are structured and how to use the OpenACC compiler, building and running your program in the cloud on Amazon’s AWS. Building upon this first example, you will create a parallel program using the “parallel” directive. We will then have a closer look at the OpenACC memory model, learning how to manage data transfers both implicitly and explicitly. Particular focus will be on using compiler feedback and performance analysis to guide development, understanding how to manage data, especially in cases with a nested call graph.  This is a “bring your own computer” hands-on tutorial.
