From CPS615-Introduction-Course,Driving Technology and HPCC Current Status and Futures CPS615 Basic Simulation Track for Computational Science -- Fall Semester 97. by Geoffrey C. Fox


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
Local and Global Parallelism
Should both be Exploited
