Details of PetaSIM and its relationship to Performance Specification Languages

Given by Yuhong Wen, Geoffrey C. Fox at Darpa Workshop on Performance Engineered Systems Annapolis Md. on August 19-21 1998. Foils prepared August 22 98

Remember 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 itself as IDL to specify object structure of computers and problems
  • Nodeset & Linkset; Dataset & Distribution; Execution Script
  • Relation to general PSL (Performance Specification Language) concept
Sample PetaSIM Experimental Results
Current Progress and next steps
