University of Tennessee Conference Center, Knoxville, Tennessee

Description:

OpenCL™ is a standard for programming heterogeneous computers built from CPUs, GPUs and other processors. It includes a framework to define the platform in terms of a host (e.g. a CPU) and one or more compute devices (e.g. a GPU) plus a C-based programming language for writing programs for the compute devices. Using OpenCL™, a programmer can write task-based and data-parallel programs that are targeted at HPC.

In this tutorial, we will introduce OpenCL™. This will be a “programmer’s introduction” where we cover the ideas behind OpenCL™ but also show how these ideas are translated into source code. We will do this through a series of progressively more challenging examples--thereby providing examples that experienced programmers will need to become productive OpenCL™ programmers.
