From CPS615-Lecture on Performance(end) and Computer Technologies(start) Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 5 September 96. byGeoffrey C. Fox * Secs 165.6
In society, we see a rich set of technologies and architectures
Ant Hills
Brains as bunch of neurons
Cities as informal bunch of people
Armies as formal collections of people
With several different communication mechanisms with different trade-offs
One can walk -- low latency, low bandwidth
Go by car -- high latency (especially if can't park), reasonable bandwidth
Go by air -- higher latency and bandwidth than car
Phone -- High speed at long distance but can only communicate modest material (low capacity)
