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 *
1 Problems are large - use domain decomposition Overheads are edge effects
2 Topology of processor matches that of domain - processor with rich flexible node/topology matches most domains
3 Regular homogeneous problems easiest but
4 irregular or
5 Inhomogeneous
6 Can use local and global parallelism
7 Can handle concurrent calculation and I/O
8 Nature always uses message passing as in parallel computers (at lowest level)
