[MOAB-dev] Memory continuity

[Kanaev A.A.]

Sorry if the scheme is broken, the point was:
 - to get contiguous memory for 2d and 3d entities
 - to arrange memory for different subsets in a certain order

Hello MOAB-dev,

I read .h5m file in parallel with resolving shared entities and exchanging 1 layer of ghost cells+ faces

cells and faces are Ranges of all 3d and 2d entities corresp.

i get different subgroups of cells (owned cells, gost cells) and faces(skin faces, inner faces, interface faces, ghost faces) into different Ranges

I have loops over that Ranges inside main iterations loop

Can i get the following contiguous memory map for 2d and 3d entities' tags by using ReorderTool?


                                                                            ghost cells start
     |____________________________________________||_______________|
cells start, owned cells start           owned cells end                      ghost_cells_end,
                                                                                                      cells end

                                                  inner faces start                                          interface faces start    ghost faces start
     |___________________________||__________________________________________||_____________________||___________________________|
skin faces start,      skin faces end                                           inner faces end,     interface faces end                                       ghost faces end
non ghost faces start,                                                              non ghost faces end                                                                    faces end
faces start
