Foil 40 Comparison with other Simulator Approaches

From Details of PetaSIM and its relationship to Performance Specification Languages Darpa Workshop on Performance Engineered Systems Annapolis Md. -- August 19-21 1998. by Yuhong Wen, Geoffrey C. Fox
1 Idiosyncratic Simulation Approach
  • PetaSIM does not run the real application
  • Uses an execution script (operation abstraction) to allow variable grain size and support of memory hierarchies
  • explicit data movement
2 PetaSIM exploits loosely synchronous collective computation
3 PetaSIM runs on single processor
4 PetaSIM can easily deal with different kinds of computer architecture
5 PetaSIM can get detailed information for any aspect of the architecture
