latSubFullCB	Lattice	Subprocess, with halo, odd or even lattice
latSubBulkFL	Lattice	Subprocess, no halo, full lattice
latSubBulkCB	Lattice	Subprocess, no halo, odd or even lattice
latFull	Lattice *	Lattice with halo for the subprocess based on site_subset
latBulk	Lattice *	Halo-free lattice for the subprocess based on site_subset
lenFull	size_t	Total size of lattices with halo for the subprocess based on site_subset
lenBulk	size_t	Total size of halo-free lattices for the subprocess based on site_subset
gridDim	array<unsigned short, 4>	Process splitting policy for each dimension
haloDepth	unsigned short	Halo depth. Set to 0 for vectors and 3 for matrices.
