Member Function Documentation

§ addA()

int XC::DistributedBandGenLinSOE::addA	(	const Matrix &	m,
		const ID &	id,
		double	fact = `1.0`
	)

virtual

Assembles fact times the matrix m into the matrix A.

First tests that loc and M are of compatible sizes; if not a warning message is printed and a $-1$ is returned. The LinearSOE object then assembles fact times the Matrix {M} into the matrix $A$. The Matrix is assembled into $A$ at the locations given by the ID object loc, i.e. $a_{loc(i),loc(j)} += //! fact * M(i,j)$. If the location specified is outside the range, i.e. $(-1,-1)$ the corresponding entry in M is not added to $A$. If fact is equal to $0.0$ or $1.0$, more efficient steps are performed. Returns $0$.

Parameters

m	matrix to assemble.
id	row identifiers.
fact	factor.

Reimplemented from XC::BandGenLinSOE.

§ addB()

int XC::DistributedBandGenLinSOE::addB	(	const Vector &	v,
		const ID &	id,
		const double &	fact = `1.0`
	)

virtual

assemblies v multiplied by factor into vector B.

First tests that loc and V are of compatible sizes; if not a warning message is printed and a $-1$ is returned. The LinearSOE object then assembles fact times the Vector V into the vector $b$. The Vector is assembled into $b$ at the locations given by the ID object loc, i.e. $b_{loc(i)} += fact * V(i)$. If a location specified is outside the range, e.g. $-1$, the corresponding entry in V is not added to $b$. If fact is equal to $0.0$, $1.0$ or $-1.0$, more efficient steps are performed. Returns $0$.

Parameters

v	vector to add.
id	row indexes.
fact	factor that multiplies v.

Reimplemented from XC::LinearSOEData.

§ recvSelf()

int XC::DistributedBandGenLinSOE::recvSelf ( const CommParameters & cp )

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.

Reimplemented from XC::BandGenLinSOE.

§ sendSelf()

int XC::DistributedBandGenLinSOE::sendSelf ( CommParameters & cp )

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.

Reimplemented from XC::BandGenLinSOE.

§ setB()

int XC::DistributedBandGenLinSOE::setB	(	const Vector &	v,
		const double &	fact = `1.0`
	)

virtual

Sets B= v*fact.

First tests that V and the size of the system are of compatible sizes; if not a warning message is printed and a $-1$ is returned. The LinearSOE object then sets the vector b to be fact times the Vector V. If fact is equal to $0.0$, $1.0$ or $-1.0$, more efficient steps are performed. Returns $0$.

Parameters

v	vector to add.
fact	factor that multiplies v.

??? LCPT (must not set B to 0?).

Reimplemented from XC::LinearSOEData.

§ setSize()

int XC::DistributedBandGenLinSOE::setSize ( Graph & theGraph )

virtual

Compute the size of the system from the graph.

The size of the system is determined by looking at the adjacency ID of each Vertex in the Graph object G. This is done by first setting kl and ku equal to $0$ and then checking for each Vertex in G, whether any of the vertex tags in the Vertices adjacency ID results in kl or ku being increased. Knowing kl, ku and the size of the system (the number of Vertices in G), a check to see if the previously allocated 1d arrays for $A$, $x$ and $b$ are large enough. If the memory portions allocated for the 1d arrays are not big enough, the old space is returned to the heap and new space is allocated from the heap. Prints a warning message if not enough memory is available on the heap for the 1d arrays and returns a $-1$. If memory is available, the components of the arrays are zeroed and $A$ is marked as being unfactored. If the system size has increased, new Vector objects for $x$ and $b$ using the {(do//! uble*,int)} Vector constructor are created. Finally, the result of invoking setSize() on the associated Solver object is returned.

Reimplemented from XC::BandGenLinSOE.

§ solve()

int XC::DistributedBandGenLinSOE::solve ( void )

virtual

Computes the solution of the system of equations.

Causes the SystemOfEqn object to invoke solve() on the currently associated solver object. Returns a $0$ if successful, negative number if not; the actual value depending on the LinearSOESolver. To solve a linear system of equations means to find $x$ such that the equation $Ax=b$ is satisfied.
