class ProfileSPDLinDirectThreadSolver: public LinearSOESolver

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.

A unique class tag (defined in <classTags.h>) is passed to the ProfileSPDLinSolver constructor.

Does nothing.

The solver first copies the B vector into X. FILL IN The solve process changes \(A\) and \(X\).
