OpenCL: A Hands-On Introduction

SESSION: OpenCL: A Hands-On Introduction

EVENT TYPE: Tutorials

TIME: 8:30AM - 5:00PM

Presenter(s):Tim Mattson, Alice Koniges, Simon McIntosh-Smith


OpenCL is an open standard for programming heterogeneous parallel computers composed of CPUs, GPUs and other processors. OpenCL consists of a framework to manipulate the host CPU and one or more compute devices (CPUs, GPUs or accelerators), and a C-based programming language for writing programs for the compute devices. Using OpenCL, a programmer can write parallel programs that harness all of the resources of a heterogeneous computer. In this hands-on tutorial, we will introduce OpenCL. For ease of learning we will focus on the easier to use C++ API, but attendees will also gain an understanding of OpenCLs C API. The format will be a 50/50 split between lectures and exercises. Students will use their own laptops (Windows, Linux or OS/X) and log into a remote server running an OpenCL platform on a range of different processors. Alternatively, students can load OpenCL onto their own laptops prior to the course (Intel, AMD and NVIDIA provide OpenCL SDKs. Apple laptops with X-code include OpenCL by default). By the end of the course, attendees will be able to write and optimize OpenCL programs, and will have a collection of example codes to help with future OpenCL program development.
