Two Processor Time Warp Analysis: Capturing the Effects of Message Queueing and Rollback/State Saving Costs
UNIVERSITY OF SOUTHERN CALIFORNIA MARINA DEL REY INFORMATION SCIENCES INST
Pagination or Media Count:
We present two new models and their exact analysis for the problem of two processors running the Time Warp distributed simulation protocol. Our first model addresses the queueing of messages at each processor while the second model adds costs for rollback and state saving. Both models provide insight into the operation of freerunning systems synchronized by rollback.
