OK, well it sounds like those guys had different ideas.  But also that
the GA designers could add the extra ports at much lower cost in chip
area.  Or if it really only takes a few dozen transistors, maybe there
could even be "chess knight" connections (requiring routing around or
through neighboring nodes, but still keeping distances fairly short), so
each interior node could reach 16 other nodes.

That's possible.  But, for example, the obvious way to implement the AES
block cipher involves around 768 bytes of ram (basically three 256-byte
arrays).  So fine, one node's ram turns into 128 bytes with some
bit-twiddling, so use 6 nodes for ram plus 1 or 2 for processing.  But
then routing the data around these nodes starts presenting problems of
its own.  AES might be doable in 5 nodes (replacing some table lookups
with parallel computation) without too much speed hit, but it would take
some simulation to find out.  That's just one example though, that I
happened to be thinking about.

I hope GA will publish some more materials soon, explaining the
concurrency mechanisms.  Actually it occurs to me that I can already
look at the Seaforth docs for that, so maybe I'll do that tonight.

I mean hypercube connectivity on the chip, the same type of ultra-fast
ports that are on the GA nodes now, but reaching further away.  There
might be a slight speed penalty from driving signals over a longer
distance, and the wiring might burn some chip area, but it may be worth
sacrificing a few nodes for it.  So instead of GA144 it might be GA128.
