WebApr 30, 1995 · Essentially, parallel factorization divides and solves the problem by the following steps: 1. Factor the original matrix into a product of a block matrix (that can be divided up between processors) and a reduced matrix, which couples the block problems. 2. Solve each block problem with one processor. 3. WebMay 4, 2024 · Yes: Schur complement formulation. Your system is equivalent to the larger one. [ 0 B B T A T] [ y z] = [ − b 0] with b = A x (which you can simply compute) and z = − B − 1 b.
