Detailed Description

template<int dim>
class CUDAWrappers::internal::HangingNodes< dim >

This class creates the mask used in the treatment of hanging nodes in CUDAWrappers::MatrixFree. The implementation of this class is explained in Section 3 of Matrix-Free Finite-Element Computations On Graphics Processors With Adaptively Refined Unstructured Meshes by Karl Ljungkvist, SpringSim-HPC, 2017 April 23-26.
