Foil 27 PetaSIM and the IPG I

From A Coarse Grain Performance Estimator -- PetaSIM and a Hybrid Distributed Object Model for the IPG NASA Workshop on Performance Engineered Information Systems -- Sept 28-29 98. by Geoffrey C. Fox, Yuhong Wen, Wojtek Furmanski, Tom Haupt
We can exploit hierarchical view of metaproblem and use PetaSIM to model the collection of "middle-tier" modules
  • Requires extension of linkset object to handle geographically extensive networks
  • Requires models of performance of modules which could be parallel simulations
Rather than support general case, consider two examples
  • Multimedia datastreams as in collaborative sessions
  • Dataflow linkage of a few computational / visualization / database modules
  • Their integration in "full" collaborative engineering
