## Description

Built-in work-item functions can be used to query the number of dimensions, the global and local work size specified to clEnqueueNDRangeKernel, and the global and local identifier of each work-item when this kernel is being executed on a device. The number of dimensions, the global and local work size when executing a kernel using the function clEnqueueTask is one.
