Foil 8 METHODOLOGY

From GCF Talk U - Lewis/NASA 3/9/92 Mardi Gras Conference on Concurrent Computing in Physical Sciences -- February 18, 1993. by Geoffrey C. Fox


1 Simple, but general and extensible to many more nodes is domain decomposition
2 All successful concurrent machines with
  • Many nodes
  • High performance (this excludes Dataflow) Have obtained parallelism from "Data Parallelism" or "Domain Decomposition"
3 Problem is an algorithm applied to data set Obtain concurrency by acting on data concurrently. The three architectures considered here differ as follows:
  • MIMD Distributed Memory Processing and Data Distributed
  • MIMD Shared Memory Processing Distributed
  • SIMD Distributed Memory Synchronous Processing on Distributed Data
