Detailed Description

Class designed to perform the Reverse Cuthill-McKee numbering scheme on the vertices of a graph.

This is done by invoking the number() method with the Graph to be numbered.

Reference: Cuthill–McKee algorithm.

Constructor & Destructor Documentation

◆ RCM()

XC::RCM::RCM ( bool  gps = true)
protected

Constructor.

The flag GPS is used to mark whether the Gibbs-Poole-Stodlmyer algorithm is used to determine a starting vertex when no starting vertex is given.

Member Function Documentation

◆ number() [1/2]

const XC::ID & XC::RCM::number ( Graph theGraph,
int  startVertex = -1 
)
virtual

Method to perform the Reverse Cuthill-mcKenn numbering scheme.

The user can supply a starting vertex, if none is provided the first vertex returned by the iter is used. If minDegree flag is set to true, at each level set the adjacent vertices not yet added from a vertex in the previous level set are added in descending degree. The result of the numbering scheme is returned in an ID which contains the references for the vertices.

side effects: this routine changes the color of the vertices. If the present ID used for the result is not of size equal to the number of Vertices in theGraph, it deletes the old and constructs a new ID. Starts by iterating through the Vertices of the graph setting the tmp variable of each to \(-1\). The Vertices are then numbered using a depth first sort of the Graph, with each unmarked Vertex in the Graph at a distance \(d\) from starting Vertex being placed in the d'th level set. As this is RCM, the Vertices in level set \(n\) are assigned a higher number than those in level set \(n+1\) with the tmp variable of the starting Vertex being assigned numVertices \(-1\). The tags of the Vertices are placed into the ID at location given by their tmp variable. These are replaced with the ref variable of each Vertex, which is returned on successful completion.

The Vertex chosen as the starting Vertex is the one whose tag is given by lastVertex. If this is \(-1\) or the Vertex corresponding to lastVertex does not exist then another Vertex is chosen. If the GPS flag in constructor is false the first Vertex from the Graphs VertexIter is used; if true a RCM numbering using the first Vertex from the VertexIter is performed and the Vertices in the last level set are then used to create an ID lastVertices with which {number(theGraph, lastVertices)} can be invoked to determine the numbering.

Implements XC::GraphNumberer.

◆ number() [2/2]

const XC::ID & XC::RCM::number ( Graph theGraph,
const ID startVertices 
)
virtual

Determine the best starting vertex.

This method is invoked to determine the best starting Vertex for a RCM using a Vertex whose tag is in lastVertices. To do a RCM numbering is performed using each of the Vertices in {startVertices} as the Vertex in level set \(0\). The Vertex which results in the numbering with the smallest profile is chosen as the starting Vertex. The RCM algorithm outlined above is then called with this starting Vertex.

Implements XC::GraphNumberer.

◆ recvSelf()

int XC::RCM::recvSelf ( const Communicator comm)
virtual

Receive the object.

Each object has to receive the data needed to be able to recreate itself in the new process after it has been sent through cp. If the object is an aggregation containing other objects, new objects of the correct type can be constructed using #theBroker. To return 0 if successful or a -1 if not.

Implements XC::MovableObject.

◆ sendSelf()

int XC::RCM::sendSelf ( Communicator comm)
virtual

Send the object.

Each object has to send the data needed to be able to reproduce that object in a remote process. The object uses the methods provided by cp object to send the data to another channel at the remote actor, the address of the channel is set before this method is called. An object of similar type at the remote actor is invoked with a receiveSelf() to receive the data. Returns 0 if successful (successful in that the data got to the channel), or a - if no data was sent.

Implements XC::MovableObject.
