Detailed Description
solves a ProfileSPDLinSOE object using the LDL^t factorization.
A ProfileSPDLinDirectBlockSolver object can be constructed to solve a ProfileSPDLinSOE object. It does this by direct means, using the \(LDL^t\) variation of the cholesky factorization. The matrix \(A\) is factored one block row at a time using a right-looking approach. No BLAS or LAPACK routines are called for the factorization or subsequent substitution.
Member Function Documentation
§ recvSelf()
|
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()
|
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.
