Local workgroup size = NULL OpenCL

Is there a way to get the used local workgroup size, when you set the value of the local workgroup size in the enqueueNDRangeKernel() function to NULL?

There is no standard runtime API for doing this in OpenCL. If you really need to know, you could have the kernel retrieve the work-group size with the get_local_size() function and store the value(s) to a buffer.

The vendor profilers (AMD's CodeXL, Intel's VTune, NVIDIA's command-line profiler) should also tell you what they picked.
