GPU-Aware AMR on Octree-Based Grids.

Algorithms for refinement/coarsening of octree-based grids entirely on GPU are proposed. Corresponding CUDA/OpenMP implementations demonstrate good performance results which are comparable with p4est library execution times. Proposed algorithms permit to perform all dynamic AMR procedures on octree-based grids entirely in GPU as well as solver kernels without exploiting CPU resourses and pci-e bus for grid data transfers.
