Foil 24 Global and Local Parallelism Illustrated by Hadrian's Wall

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	Global Parallelism Break up domain Amount of Parallelism proportional to size of problem (and is usually large) Unit is Bricklayer or Computer node
2	Local Parallelism Do in parallel local operations in the processing of basic entities e.g. for Hadrian's problem, use two hands, one for brick and one for mortar while ... for computer case, do addition at same time as multiplication Local Parallelism is limited but useful
3	Local and Global Parallelism
4	Should both be Exploited
