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.
