A ShedHeaviest is an object used to balance a PartitionedDomain.
It does this by shedding the boundary vertices on the heaviest loaded partition (subdomain).
XC::ShedHeaviest::ShedHeaviest | ( | double | fG, |
int | rels, | ||
bool | disallowDisconnected | ||
) |
Constructor.
Sets the parameters used in the balance() method.
fG | factor greater. |
rels | number of releases. |
|
virtual |
The heaviest loaded partition, max
, is first determined by iterating through the Graph theWeightedGraph
looking at the vertex weights.
Then {releaseBoundary(max, theWieightedGraph, true, factorGreater)} is invoked on the DomainPartitioner numRelease
times. Returns \(0\) if successful, otherwise a negative number and a warning message are returned if either no link has been set to the DomainPartitioner or {releaseBoundary()} returns a negative number.
Implements XC::LoadBalancer.
