tree_d_3d.kernels.quadtree_scatter.quadtree_scatter_metal

The Metal version (Apple-silicon GPU) of the quadtree_scatter kernel.

quadtree_scatter_pyccel.py next to this file is the CPU version with the same arguments. One thread per sorted slot, each writing its own target slot (the targets are a permutation); integer only, so exact. See :mod:tree_d_3d.kernels._metal.
