OpenCL 1.1 specifications
« on: June 15, 2010, 12:48:00 AM »
OpenCL 1.1 includes significant new functionality including::

    * Host-thread safety, enabling OpenCL commands to be enqueued from multiple host threads;
    * Sub-buffer objects to distribute regions of a buffer across multiple OpenCL devices;
    * User events to enable enqueued OpenCL commands to wait on external events;
    * Event callbacks that can be used to enqueue new OpenCL commands based on event state changes in a non-blocking manner;
    * 3-component vector data types;
    * Global work-offset which enable kernels to operate on different portions of the NDRange;
    * Memory object destructor callback;
    * Read, write and copy a 1D, 2D or 3D rectangular region of a buffer object;
    * Mirrored repeat addressing mode and additional image formats;
    * New 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 event objects to OpenGL fence sync objects;
    * Optional features in OpenCL 1.0 have been bought into core OpenCL 1.1 including: writes to a pointer of bytes or shorts from a kernel, and conversion of atomics to 32-bit integers in local or global memory.
