A Coarse Grain Performance Estimator -- PetaSIM and a Hybrid Distributed Object Model for the IPG

Given by Geoffrey C. Fox, Yuhong Wen, Wojtek Furmanski, Tom Haupt at NASA Workshop on Performance Engineered Information Systems on Sept 28-29 98. Foils prepared Sept 30 98

PetaSIM Motivation and basic ideas
  • (Using aircraft analogy) aimed at conceptual design of computer architecture and applications ( as opposed to later preliminary and detailed design)
  • Java applet as friendly user interface; C++ execution engine
PetaSIM Design and Examples
  • as conceptual level, can use to estimate performance of applications in any language
  • Like RMI, use Java to specify object structure of computers and problems -- need to integrate with other PSL
Sample PetaSIM Experimental Results
A hybrid object web model for IPG (Information Power Grid)
Possible use of PetaSIM in IPG for two classes of applications
  • Multimedia transport in collaborative systems
  • Collection of coarse grain data flow modules
