The book starts with the basics of parallelization, covers the main concepts, grammar, and setting up a development environment for OpenCL, concluding with source-code walkthroughs of the FFT and Mersenne Twister algorithms written in OpenCL. The revised edition includes a summary of changes made in OpenCL Specification 1.2, reference functions corresponding to 1.2, and updated excursion environments. It is highly recommended for those wishing to get started on programming in OpenCL.
NVIDIA announces the dual-chip GeForce GTX 690, powered by two Kepler-generation GK104 graphics processors. With the help of 3072 stream processors, the device is set to establish new performance records. The card supportsOpenGL 4.2, OpenCL 1.2 and DirectX 11.1.
Kishonti Informatics has launched the community version of CLBenchmark 1.1 Desktop Edition. CLBenchmark provides a free and easy-to-use tool for consumers and media professionals to compare the processing power of different hardware architectures.
AMD gDEBugger offers real-time OpenCL kernel debugging, which allows developers to step into the kernel execution directly from the API calls, debug inside the kernel, view all variable values across different work groups and work items. The new gDEBugger v6.2 adds Linux Support and support for OpenCL 1.2 beta drivers
Intel has released the Intel SDK for OpenCL Applications 2012 to support 3rd generation Intel Core processors. Supported seamlessly by the Intel HD Graphics Driver, OpenCL developers can now use compute resources across both the Intel CPU and Intel HD Graphics 4000. The SDK also supports interoperability with graphics and media APIs including Microsoft DirectX, OpenGL, and the Intel Media SDK.
AMD today announced a collaboration with Adobe Systems Incorporated to optimize a new set of GPU-accelerated features for Adobe products including the newly announced Adobe Photoshop CS6. Implementing GPU acceleration and incorporating OpenCL optimization improves the end-user experience by dramatically speeding up critical imaging features and generating real-time results when editing with key tools in Adobe Creative Suite 6.
Adobe announced that they will be using their newly enhanced Adobe Mercury Playback Engine that incorporates OpenCL heterogeneous compute for the very first time on a number of Apple MacBook Pro laptops with AMD Radeon graphics.
The OpenCL hardware acceleration features in the Generic Graphics Library (GEGL) were originally developed as part of Google's Summer of Code in 2009 and 2011 and finished over the winter with sponsorship from AMD and help by MulticoreWare. On supported systems, this feature should greatly speed up processor intensive operations. Users have to start the application with the command line parameter GEGL_USE_OPENCL=yes to use OpenCL.
