/**
 * Native bindings to the intel_subgroups extension.
 * 
 * 

The goal of this extension is to allow programmers to improve the performance of their applications by taking advantage of the fact that some work * items in a work group execute together as a group (a "subgroup"), and that work items in a subgroup can take advantage of hardware features that are * not available to work items in a work group. Specifically, this extension is designed to allow work items in a subgroup to share data without the use * of local memory and work group barriers, and to utilize specialized hardware to load and store blocks of data.

* *

There is a large amount of overlap between the functionality in this extension and the functionality in the Khronos OpenCL 2.0 "cl_khr_subgroups" * extension, so this extension reuses many of the names, concepts, and functions already described in the cl_khr_subgroups extension. The key differences * between the Intel subgroups extension and the Khronos subgroups extension are:

* *
    *
  • The Khronos subgroups extension requires OpenCL 2.0, but the Intel subgroups extension may be available on OpenCL 1.2 devices.
  • *
  • The Khronos subgroups extension guarantees that subgroups in a work group will make independent forward progress, but the Intel extension does not * guarantee that subgroups in a work group will make independent forward progress.
  • *
  • The Intel extension adds a rich set of subgroup "shuffle" functions to allow work items within a work group to interchange data without the use of * local memory and work group barriers.
  • *
  • The Intel extension adds a set of subgroup "block read and write" functions to take advantage of specialized hardware to read or write blocks of * data from or to buffers or images.
  • *
  • The Intel subgroups extension does not include the subgroup pipes functions that are included as part of the Khronos subgroups extension.
  • *
  • The Intel subgroups extension does not include the device-side kernel query functions for subgroups that are included as part of the Khronos * subgroups extension.
  • *
* *
