Instructor-Led Workshop
Fundamentals of Accelerated Computing with OpenACC

Request a workshop for your organization

Notify me when public workshops are available

This workshop covers the fundamental tools and techniques needed for accelerating C/C++ or Fortran applications to run on massively parallel GPUs with OpenACC. You will learn how to write code, configure code parallelization with OpenACC, optimize memory movements between the CPU and GPU accelerator, and implement the workflow that you have learned on a new task—accelerating a fully functional, but CPU-only, Laplace Heat Equation code for massive performance gains. At the end of the workshop, you will have access to additional resources for creating new GPU-accelerated applications on your own.

Learning Objectives

By participating in this workshop, you’ll have an understanding of the fundamental tools and techniques for GPU-accelerating C/C++ or Fortran applications with OpenACC and be able to:

Profile and optimize your CPU-only applications to identify hot spots for acceleration.
Use OpenACC directives to GPU-accelerate your codebase.
Optimize data movement between the CPU and GPU accelerator.
