Detailed Description

solves a ProfileSPDLinSOE object using the LDL^t factorization (threaded version).

A ProfileSPDLinDirectThreadSolver object can be constructed to solve a ProfileSPDLinSOE object. It does this in parallel using threads by direct means, using the \(LDL^t\) variation of the cholesky factorization. The matrx \(A\) is factored one row block at a time using a left-looking approach. Within a row block the factorization is performed by \(NP\) threads. No BLAS or LAPACK routines are called for the factorization or subsequent substitution.

§ ProfileSPDLinDirectThreadSolver()

XC::ProfileSPDLinDirectThreadSolver::ProfileSPDLinDirectThreadSolver	(	int	numProcessors,
		int	blckSize,
		double	tol
	)

protected

Constructor.

Parameters

numProcessors number of processors to use.

Member Function Documentation

§ recvSelf()

int XC::ProfileSPDLinDirectThreadSolver::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.

Implements XC::MovableObject.

§ sendSelf()

int XC::ProfileSPDLinDirectThreadSolver::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.

Implements XC::MovableObject.

§ solve()

int XC::ProfileSPDLinDirectThreadSolver::solve ( void )

virtual

The solver first copies the B vector into X.

FILL IN The solve process changes \(A\) and \(X\).

Implements XC::ProfileSPDLinSolver.
