This variable controls how the grid points are mapped to a
linear array. This influences the performance of the code.
The grid is mapped using small parallelepipedic grids. The size
of the blocks is controlled by MeshBlockSize.
The grid is mapped using a full cube, i.e. without blocking.
Use the ordering from the global mesh
grid/par_vec.F90 : 470
