Concept of a Logical Process Simulation
Two kinds of events are processed in each LPi:
internal events have causal impact only to Si ? S
external events also affect Sj ? S (i?j), the local states of other LPs.
A communication interface CIi attached to the SE takes care for the propagation of effects causal to events to be simulated by remote LPs, and the proper inclusion of causal effects to the local simulation as produced by remote LPs.
Two approaches: conservative, optimistic
The main mechanism for this is the sending, receiving and processing of event messages piggy-backed with copies of the senders LVT at the sending instant.
