Interface AugmentedNodeRanking

All Superinterfaces:

NodeRanking

public interface AugmentedNodeRanking

extends NodeRanking

Node ranking as augmented by the algorithm chassis.

Design rationale

Presumably a node ordering policy first needs to compute an initial ordering of nodes. In order to do this as easily as possible, the node ordering policy needs to know the number of ranks and the number of nodes in each rank, so that the node ordering policy can directly allocate a properly shaped area of storage for storing the ordering, if necessary.

Method Summary

int[]

rankToNumNodesTable() rankToNumNodesTable()[rankIdx] is the number of nodes in rank rankIdx.

Method Detail

rankToNumNodesTable

public int[] rankToNumNodesTable()

rankToNumNodesTable()[rankIdx] is the number of nodes in rank rankIdx. Modifying the returned array has undefined consequences.

Rationale: This way of representing the number of nodes in each rank makes it very easy to define a [re]usable method that creates a properly shaped area of storage for storing the ordering.
