The Mathematica documentation (section "Details": https://reference.wolfram.com/mathematica/OpenCLLink/ref/OpenCLFunction.html) states that:
On launch, if the number of threads is not specified (as an extra argument to the ), then the dimension of the element with largest rank and dimension is chosen. For images, the rank is set to 2.
Great - but how do I do that when I call an OpenCL Function? There is so documentation for that..
Thanks
