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


Simple, but general and extensible to many more nodes is domain decomposition
All successful concurrent machines with
  • Many nodes
  • High performance (this excludes Dataflow) Have obtained parallelism from "Data Parallelism" or "Domain Decomposition"
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
