OpenCL 1.1 Specification Release

| | 0 Comments| 09:28

這是昨天的消息,原文請參考《Khronos Drives Momentum of Parallel Computing Standard with Release of OpenCL 1.1 Specification》,OpenCL 的頁面也已經更新了。而在 OpenCL 1.1 裡,比較重要的新功能有:

  • 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.


而目前 AMD 和 nVIDIA 似乎都還沒有更新他們產品到 OpenCL 1.1,一般程式開發者要用可能還要等等了。
