Introduction
OpenCLTM (Open Computing Language) is an open, royalty-free, cross-platform standard specifically designed for general purpose parallel programming of heterogeneous systems, including modern desktop and workstation class multi-core processors (CPUs), graphics processing units (GPUs), and other accelerators such as Cell and digital signal processors (DSPs). The standard includes an API for coordinating execution between devices and a cross-platform parallel programming language. Based on ISO C99, the OpenCL-C language provides a well-defined execution environment with strict precision requirements, allowing device agnostic kernel methods to be written which can be run on any supported OpenCL device. The OpenCL standard supports task-based and data-based parallel computing, features consistent numerical requirements based on the IEEE standard for floating-point arithmetic (IEE 754), defines a configuration profile for handheld and embedded devices and efficiently interoperates with OpenGL, OpenGL ES, and other graphics APIs.
Aim
The aim of the OpenCL workshop will be to provide registered attendees with an intensive one-day course that covers both a general introduction as well more advanced topics showcasing OpenCL as a technology platform. Speakers from both industry and academia will discuss a range of subjects, including core fundamentals, hardware architectures, parallel programming, as well as workload scheduling and device specific optimizations.
