Foil 27 Comparison of Concurrent Processing in Society and Computing

From Second set of lectures on CPS615 Parallel Computing Overview CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox *
Problems are large - use domain decomposition Overheads are edge effects
Topology of processor matches that of domain - processor with rich flexible node/topology matches most domains
Regular homogeneous problems easiest but
irregular or
Inhomogeneous
Can use local and global parallelism
Can handle concurrent calculation and I/O
Nature always uses message passing as in parallel computers (at lowest level)
