Logical Process Simulation -- Implementation
Synchronous LP simulation
- implements VT as a global clock
- explicitly as a centralized shared data structure, or
- implicitly by a time-stepped execution procedure
- each LP at any point in real time faces same value of VT
-
Asynchronous LP simulation
- every LP maintains local VT (LVT)
- generally different LVT values at a given point in real time
- event causality preservation by ordering according to relative LVT values
