/**
* This benchmark created on August 31, 2022.
*
* The remap procedure from NAS UA benchmark.
* UA = Unstructured Adaptive mesh, dynamic and irregular memory access.
*
* Description of remap:
* After a refinement, map the solution from the parent (x) to
* the eight children. y is the solution on the first child
* (front-bottom-left) and y1 is the solution on the next 7 children.
*
* Web address: https://www.nas.nasa.gov/software/npb.html
