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