The Khronos[tm] Group announced the ratification and public release of the OpenCL[tm] 1.1 specification, the latest version of the open, royalty-free standard for cross-platform, parallel programming of modern processors. OpenCL 1.1 provides enhanced performance and functionality for parallel programming in a backwards compatible specification that is the result of cooperation between industry-leading companies. OpenCL working group members include: AMD, Apple, ARM, Blizzard Activision, Broadcom, Codeplay, Electronic Arts, Ericsson, Freescale, Graphic Remedy, IBM, Imagination Technologies, Intel, Kestrel Institute, Los Alamos National Laboratory, Movidia, Nokia, NVIDIA, Petapath, Presagis, Qualcomm, Renesas, S3 Graphics, Seaweed Systems, Sony, ST-Ericsson, STMicroelectronics, Symbian, and Texas Instruments. Khronos also announced the release of a C++ wrapper API for use with OpenCL, and the immediate availability of OpenCL 1.1 conformance tests.
“The clear commercial opportunity to unleash the power of heterogeneous parallel processing that drove multiple OpenCL 1.0 implementations has also fueled the ongoing industry cooperation to create OpenCL 1.1,” said Neil Trevett, chair of the OpenCL working group, president of the Khronos Group and vice president at NVIDIA. “The OpenCL 1.1 specification is being released 18 months after OpenCL 1.0 to enable programmers to take even more effective advantage of parallel computing resources while protecting their existing investment in OpenCL code.”
OpenCL 1.1 adds significant functionality for enhanced parallel programming flexibility, functionality and performance including:
- New data types including 3-component vectors and additional image formats
- Handling commands from multiple hosts and processing buffers across multiple devices
- Operations on regions of a buffer including read, write and copy of 1D, 2D or 3D rectangular regions
- Enhanced use of events to drive and control command execution
- Additional OpenCL C built-in functions such as integer clamp, shuffle and asynchronous strided copies
- Improved OpenGL interoperability through efficient sharing of images and buffers by linking OpenCL and OpenGL events
Khronos OpenCL Members Speak and Demo at SIGGRAPH Los Angeles July 27-29, 2010
Members of the press and developers alike are invited to attend the BOF “Birds of a Feather” on Tuesday, 27 July, 2010 from 4:00 pm – 6:00 pm at the SIGGRAPH trade show at Los Angeles Convention Center, Room 402A. There the audience will meet designers and implementers of this significant standard for heterogeneous parallel programming on GPUs and CPUs, and learn how OpenCL inter-operates with OpenGL, enabling advanced, cross-platform, visual computing applications. Guests are also invited to view demos on the Khronos booth #1201 and pickup a free laminated reference card for a number of our APIs, including OpenCL and OpenGL.

About The Khronos Group
The Khronos Group is an industry consortium creating open standards to enable the authoring and acceleration of parallel computing, graphics and dynamic media on a wide variety of platforms and devices. Khronos standards include OpenGL®, OpenGL® ES, WebGL, EGL, OpenCL, OpenMAX, OpenVG, OpenSL ES, OpenKODE and COLLADA. All Khronos members are able to contribute to the development of Khronos specifications, are empowered to vote at various stages before public deployment, and are able to accelerate the delivery of their cutting-edge media platforms and applications through early access to specification drafts and conformance tests. More information is available at www.khronos.org
