ProfileSPDLinSOE * | theSOE |
Skypakc based linear SOE solver.
A ProfileSPDLinDirectSkypackSolver object can be constructed to solve a ProfileSPDLinSOE object. It does this by direct means using the routines supplied in the SKYPACK library, a library which uses the BLAS levels 1,2 and 3 for the factorization and substitution. The routines in SKYPACK require a number of work areas: {int block[3]} and {double invD[size]}. In addition, to allow the use of the BLAS 2 and 3, work areas {double rw[mRows x mCols]}, {double tw[mRows x mRows]} and {int index[max(mCols,mRows)]} are created.
XC::ProfileSPDLinDirectSkypackSolver::ProfileSPDLinDirectSkypackSolver | ( | void | ) |
Default constructor.
Sets mCols
and mRows
equal to \(0\) and does not try and allocate any memory for the work arrays.
XC::ProfileSPDLinDirectSkypackSolver::ProfileSPDLinDirectSkypackSolver | ( | int | Mcols, |
int | Mrows | ||
) |
Constructor.
Sets mCols
and mRows
and allocates space in memory for the work arrays rw
, tw
and index
. If not enough memory is available in memory, mCols
and mRows
is set equal to \(0\) and an error message is printed.
|
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.
|
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.
|
virtual |
Set the size of the system.
Is responsible for setting the block
information required by the SKYPACK routines (block[0]=1; block[1]=size, block[2]=1) and for creating space for the invD
work array. Returns \(0\) if successfull, otherwise a warning message is printed and a \(-1\) is returned.
Implements XC::LinearSOESolver.

Solve the system of equations.
The solver first copies the B vector into X and then solves the BandSPDLinSOE system. If the matrix has not been factored, the matrix is first factored using the SKYPACK routine skysf2(), if {mCols} and mRows
equal \(0\), or skypf2()}. {skysf2() is a routine which uses the BLAS level 1 routines, skypf2() is a routine which uses BLAS levels 2 and 3. If skypf2() has been called, invD
is set up. Once the matrix has been factored, skyss() is called. If the solution is sucessfully obtained, i.e. the skyss() routine returns \(0\) in the INFO argument, \(0\) is returned, otherwise it prints a warning message and returns INFO. The solve process changes \(A\) and \(X\).
Implements XC::ProfileSPDLinSolver.
