tree_d_3d.kernels.log_quadtree_moments.log_quadtree_moments_pyccel

The Pyccel version (CPU) of the log_quadtree_moments kernel of the Barnes-Hut and FMM solvers.

log_quadtree_moments_cuda.cu next to this file is the CUDA version (GPU) and log_quadtree_moments_numpy.py the version for machines without Pyccel, all with the same arguments; the folder’s __init__.py declares the kernel (see :mod:tree_d_3d.kernels). The flat quadtree is described in :mod:tree_d_3d.flat_tree.
