I've got to say it - what's the hassle in gigabit ethernet?
Don't want to shoot down a good idea - hell I've floated some daft
schemes on GLLUG in my time, and ideas like this are always fun.

But with twin (and quad) gigabit built onto motherboards you can't
really fight City Hall. We have a 512 machine cluster banging away over
gigabit, and churn out gigabit based clusters every day. We get latency
down to 22us over ethernet.


For high bandwidth, the choices are 10gig ethernet and Infiniband.
I'll grant you that neither of these is low or zero cost - however you
get motherboards these days with built in Infiniband so the costs are
not so great.
