Coarse-grain: Task is broken into a handful of pieces, each executed by powerful processors.
Pieces, processors may be heterogeneous. Computation/
Communication ratio very high -- Typical of Networked Metacomputing
Medium-grain: Tens to few thousands of pieces, typically executed by microprocessors.
Processors typically run the same code.(SPMD Style)
Computation/communication ratio often hundreds or more.
Typical of MIMD Parallel Systems such as SP2, CM5, Paragon, T3D
