simgrid::kernel::routing::RoutedZone Class Reference

Detailed Description

NetZone with an explicit routing (abstract class)

This abstract class factorizes code between its subclasses: Full, Dijkstra and Floyd.

Comparison of the RoutedZone subclasses
DijkstraZoneFloydZoneFullZone
Platform-file content Only 1-hop routes (rather small) Only 1-hop routes (rather small) Every path, explicitly (very large)
Initialization time Almost nothing Floyd-Warshall algorithm: O(n^3) Almost nothing
Memory usage 1-hop routes (+ cache of routes) O(n^2) data (intermediate) O(n^2) + sum of path lengths (very large)
Lookup time Dijkstra Algo: O(n^3) not much (reconstruction phase) Almost nothing
Expressiveness Only shortest path Only shortest path Everything
