try dumb vertical scaling of inverters
...
it seems that if we take a non-inverter than has y(0) *close* to 0, and
scale it enough, then we get stable transfer.
this suggests we really just want something with a massive number of
couplings (to keep the coupling ideal) and enough asymmetric windings to
get us > 1.0 tx ratio over some range.

the larger cores may indeed be doing better (a little early to tell).
the tendency right now is that too much transfer occurs too early,
such that the region of > 1.0 slope maps _outside_ that region, not
allowing for an inverter to work well.

capture high-level GPU timing diagnostics
...
this shows that we spend about 2/3 of the GPU roundtrip time on
stepping. the other 1/3 is i guess scheduling/latency/memory transfers.

maybe it'll work better on a newer GPU.

neither of these produce good amplification.
- we expect bad amplification for 18-xx because it doesn't do any loops
with > 2 cores
- 17-xx might just need reduced drive current
