Detailed Description
A ShedHeaviest is an object used to balance a PartitionedDomain.
It does this by shedding the boundary vertices on the heaviest loaded partition (subdomain).
Constructor & Destructor Documentation
◆ ShedHeaviest()
| XC::ShedHeaviest::ShedHeaviest | ( | double | fG, |
| int | rels, | ||
| bool | disallowDisconnected | ||
| ) |
Constructor.
Sets the parameters used in the balance() method.
- Parameters
-
fG factor greater. rels number of releases.
Member Function Documentation

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.
