The AMD APP SDK 2.4 for OpenCL development is now available, providing significant enhancements in performance: reduced kernel launch time, increased transfer speed and reduced latency for PCI transfer, and zero copy transfer for APUs, and introduces support for AMD A-Series APUs. CPU support is extended with the addition of support both for Images and for Double Precision floating point (cl_khr_fp64 extension).
The OpenCL Lounge has been introduced to announce new IBM OpenCL technologies as well as to promote discussion of these technologies. Lounge members are encouraged to post issues and questions. As well, suggestions and feature requests are welcomed. Refer to the product box on the overview page for a link to the appropriate message board.
AMD recently released Catalyst™ 11.3. The AMD Accelerated Parallel Processing (APP) OpenCL runtime is now enabled by default within AMD Catalyst. Applications that leverage OpenCL for GPU based compute tasks will automatically benefit from the significant performance boost that this provides.
IBM released the OpenCL Development Kit for Linux on Power v0.3 and is available via alphaWorks. This updated offering is a fully conformant implementation of the OpenCL 1.1 specification. Other features of this release include a fully conformant implementation of the double precision extension, 32- and 64-bit atomic extensions, 64-bit application support, debugging improvements, as well as various performance improvements including full IBM POWER7* exploitation.
CMSoft brings to developers the new GLRender tool in OpenCLTemplate that automates the creation of an OpenGL scene coupled with a derived OpenCL context.
Students learn with interactive and hands-on sessions about GPU hardware, GPU languages, discovering how best to take advantage of GPUs for their computational needs. The course covers programming in both OpenCL and CUDA, pointing out the similarities and differences along the way. Topics include both the core languages and extensions including those for double precision and interfacing with OpenGL 3D graphics buffers.
OpenCL Studio combines OpenCL and OpenGL into a single integrated development environment for high performance computing. The feature rich editor, interactive scripting language and extensible plug-in architecture support the rapid development of complex parallel algorithms and accompanying visualization. The first production version of OpenCL Studio including instructional videos and demo applications are available online.
Khronos has posted slide presentations from GDC 2011 online. Included in the DevU presentations are COLLADA, Mobile, OpenCL, OpenVG and WebGL.
ConceivablyTech posted a good review of the WebGL 1.0 Spec release news and followed it up with their own speculation on WebCL. "Enabled in a browser, WebCL could open an entirely new world for cloud applications at much higher performance levels. Khronos mentioned image and video processing as well as advanced physics for web games that could come alive through WebCL."
Khronos has announced a quick reference card for WebGL 1.0 release spec. This adds to the collection of Reference Cards already available for other Khronos APIs: OpenGL, OpenCL, OpenVG, OpenMAX, OpenSL ES, COLLADA and OpenWF
