A Parallel Preconditioner for Block Tridiagonal Matrices.

1993
This paper is concerned with the solution of block tridiagonal linear algebraic systems by the preconditioned conjugate gradient (PCG) method. If we consider two splittings of the coefficient matrix, it is possible to derive a parallel additive polynomial preconditioner and to give conditions for such preconditioner to be symmetric positive definite ...
