Foil 19 Hadrian's Wall Illustrates that the Topology of Processor Must Include Topology of Problem

From Second set of lectures on CPS615 Parallel Computing Overview CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox *
1 Hadrian's Wall is one dimensional
2 Humans represent a flexible processor node that can be arranged in different ways for different problems
3 The lesson for computing is:
4 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.
