Foil 78 Hadrian's Wall Illustrates that the Topology of Processor Must Include Topology of Problem

From CPS615-Introduction-Course,Driving Technology and HPCC Current Status and Futures CPS615 Basic Simulation Track for Computational Science -- Fall Semester 98. by Geoffrey C. Fox, (Some Culler, Koelbel material)
Hadrian's Wall is one dimensional
Humans represent a flexible processor node that can be arranged in different ways for different problems
The lesson for computing is:
Original MIMD machines used a hypercube topology. The hypercube includes several topologies including all meshes. It is a flexible concurrent computer that can tackle a broad range of problems. Current machines use different interconnect structure from hypercube but preserve this capability.
