All Implemented Interfaces:

Simulator

public final class ConcurrentDESimulator
extends SequentialDESimulator

Concurrent simulator for discrete event models using multiple threads

This simulator identifies all due agents of a model using a global event queue. Then the doEventSim method of these imminent agents are called in a concurrent mode and with no specific order.

This implementation is especially useful to run DES models.

ConcurrentDESimulator

public ConcurrentDESimulator(BasicDomain root,
 EventQueue<Agent> queue,
 MessageForwardingStrategy forwarding)

Constructs a new concurrent simulator with given model, queue implementation and messaging strategy

Parameters:

root - the root domain of the model

queue - the queue implementation to use as global event queue

forwarding - the strategy to use for message forwarding

ConcurrentDESimulator

public ConcurrentDESimulator(BasicDomain root)
