Detailed Description

The abstract class of Phv allocation strategy. The AllocationStrategy controls the core of PHV allocation: matching SuperClusters to ContainerGroup by tryAllocation function. Strategies can:

1. make a complete or a partial allocation.
2. be chained with other strategies.

The result of core function tryAllocation:

1. status: the result of this strategy.
2. transaction: allocations had been made.
3. remaining_clusters: the remaining cluster;

Member Function Documentation

tryAllocation()

virtual AllocResult AllocationStrategy::tryAllocation ( const PHV::Allocation & alloc, const std::list< PHV::SuperCluster * > & cluster_groups_input, const std::list< PHV::ContainerGroup * > & container_groups )

pure virtual

Run this strategy Returns: a AllocResult that

1. status: the result of this strategy.
2. transaction: allocations had been made.
3. remaining_clusters: the remaining cluster; Strategies should not changed container_groups, except for sorting it.

Implemented in BruteForceAllocationStrategy.
