Global Parallelism
Break up domain
Amount of Parallelism proportional to size of problem (and is usually large)
Unit is Bricklayer or Computer node
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
