Foil 64 Structure(Architecture) of Portal Applications - II

From Integration of Web and Distributed Object Technologies in a New Generation of Grande Programming Environments PDPTA Las Vegas -- June 28 1999. by Geoffrey C. Fox
Modules are "natural" message-parallel components of problem and tend to have less stringent latency and bandwidth requirements than those needed to link data-parallel components
  • modules are what HPF needs task parallelism for
  • Often modules are naturally distributed whereas parts of data parallel decomposition may need to be kept on tightly coupled MPP
Assume that primary goal of metacomputing system (portal programming environment) is to add to existing parallel computing environments, a higher level supporting module parallelism
  • Now if one takes a large CFD problem and divides into a few components, those "coarse grain data-parallel components" will be supported by computational grid technology
