My plan was to keep the pipe driver interface as simple as possible and
pass the dimension as an additional *kernel* parameter directly from the
clover front-end (along with other things that we currently don't handle
and we could abstract from the pipe driver, like the grid offset). I
don't see any reason to bother the driver with this as e.g. <1> and
<1,1,1> are equivalent grid definitions that will invariably result in
the same hardware setup.
P.S.: Sorry for taking so long to get back to you, been quite busy
during the last couple of weeks.
