The Khronos Group has ratified and released a new version of the OpenCL specification, and Nvidia claims to be the first in tow with compatible drivers.
According to Khronos, the latest version of the royalty-free GPU computing spec brings "significant functionality for enhanced parallel programming flexibility, functionality and performance." This new functionality-enhancing functionality includes the following items, as described by the consortium:
- 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.
You can learn more and take a look at the new 1.1 specification by visiting the official OpenCL website. Some OpenCL 1.1 conformance tests are already available. Also, Khronos says it has released a C++ wrapper application programming interface for OpenCL.
Nvidia sent us a statement saying its "full weight is behind OpenCL 1.1, as evidenced by immediate availability of the driver on [the Nvidia] website today, along with the industry’s broadest set of tools for taking advantage of NVIDIA GPUs for general purpose computation." We're not seeing any new drivers over at the Nvidia Developer Zone, however, and the latest beta GeForce driver came out on May 24.
