Class INTELCommandQueueFamilies

java.lang.Object

org.lwjgl.opencl.INTELCommandQueueFamilies

public final class INTELCommandQueueFamilies
extends java.lang.Object

Native bindings to the intel_command_queue_families extension.

Some OpenCL devices may support different sets of command queues with different capabilities or execution properties. These sets are described in this extension as command queue families. Applications may be able to improve performance or predictability by creating command queues from a specific command queue family.

This extension adds the ability to:

• Query the command queue families supported by an OpenCL device and their capabilities.
• Create an OpenCL command queue from a specific command queue family.
• Query the command queue family and command queue index associated with an OpenCL command queue.

Requires CL20.
