Detailed Description

Abstract base class representing general load balancer monitor.

The task of the monitor is to detect the imbalance and to make the decision, whether to redistribute the work or to continue with existing partitioning. It provides partition weights, reflecting their relative computational performance. These weights should be continuously updated to reflect changing work load during solution process.

Member Function Documentation

virtual LoadBalancerDecisionType oofem::LoadBalancerMonitor::decide ( TimeStep *  )

pure virtual

Returns flag indicating whether rebalancing is necessary; should update node weights as well.

Implemented in oofem::WallClockLoadBalancerMonitor.

virtual const char* oofem::LoadBalancerMonitor::giveClassName ( ) const

pure virtual

Returns class name of the receiver.

Implemented in oofem::WallClockLoadBalancerMonitor.

const FloatArray& oofem::LoadBalancerMonitor::giveProcessorWeights ( )

inline

Returns processor weights; the larger weight means more powerful node, sum of weights should equal to one.
