What's new in OpenCL 1.1

Jun 15, 2010
  • 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.
