...
And each of these blocks of half spinors will be sized to vol_cb
sites (ie half volume only). The shift_table() for a given site and
direction indexes into one of these lines. So the offset table essentially
delineates which line one picks, by adding an offset of
3*subgrid_vol_cb*dir
To the shift. The result from offset table, can be used directly as a
pointer displacement on the temporaries.
Perhaps the best way to condsider this is to consider a value
of shift_table[type][dir/site] that lands in the body. The
shift table merely gives me a site index. But the data needs
to be different for each direction for that site index. Hence
we need to replicate the body, for each dir. The 3xsubgrid_vol_cb
is just there to take care of the buffers.
Or another way to think of it is that there is a 'body element' index
specified by the shift table lookup, and that dir is just the slowest
varying index.
