DESCRIPTION
Built-in work-item functions can be used to query the number of dimensions, the global and local work
size specified to clEnqueueNDRangeKernel(3clc), 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(3clc) is one.
