simgrid::kernel::routing::FloydZone Class Reference

Detailed Description

NetZone with an explicit routing computed at initialization with Floyd-Warshal.

The path between components is computed at creation time from every one-hop links, using the Floyd-Warshal algorithm.

This result in rather small platform file, slow initialization time, and intermediate memory requirements (somewhere between the one ofDijkstraZone} and the one ofFullZone}).

Member Function Documentation

getLocalRoute()

void simgrid::kernel::routing::FloydZone::getLocalRoute ( NetCard *  src, NetCard *  dst, sg_platf_route_cbarg_t  into, double *  latency  )

overridevirtual

Probe the routing path between two points that are local to the called NetZone.

Parameters

src	where from
dst	where to
into	Container into which the traversed links and gateway informations should be pushed
latency	Accumulator in which the latencies should be added (caller must set it to 0)

Implements simgrid::kernel::routing::NetZoneImpl.

addRoute()

void simgrid::kernel::routing::FloydZone::addRoute ( sg_platf_route_cbarg_t  route )

overridevirtual

Reimplemented from simgrid::s4u::NetZone.

seal()

void simgrid::kernel::routing::FloydZone::seal ( )

overridevirtual

Seal your netzone once you're done adding content, and before routing stuff through it.

Reimplemented from simgrid::s4u::NetZone.
