cl_khr_throttle_hints

Adds throttle hints for OpenCL, but does not specify the throttling behaviour or minimum guarantees.

#pragma OPENCL EXTENSION cl_khr_throttle_hints : enable

Description

This extension adds throttle hints for OpenCL, but does not specify the throttling behaviour or minimum guarantees. It is expected that the user guide associated with each implementation which supports this extension describe the throttling behaviour guaranteed.

If this extension is supported by an implementation, the string cl_khr_throttle_hints will be present in the CL_PLATFORM_EXTENSIONS string described in table 4.1 (see clGetPlatformInfo).

Note that the throttle hint is orthogonal to functionality defined in cl_khr_priority_hints) extension. For example, a task may have high priority (CL_QUEUE_PRIORITY_HIGH_KHR) but should at the same time be executed at an optimized throttle setting (CL_QUEUE_THROTTLE_LOW).
