Parallel solution of saddle point systems with nested iterative solvers based on the Golub-Kahan Bidiagonalization
Carola Kruse, Masha Sosonkina, Mario Arioli +2
We present a scalability study of Golub-Kahan bidiagonalization for the parallel iterative solution of symmetric indefinite linear systems with a 2x2 block structure. The algorithm…

An iterative generalized Golub-Kahan algorithm for problems in structural mechanics
Mario Arioli, Carola Kruse, Ulrich Ruede +1
This paper studies the Craig variant of the Golub-Kahan bidiagonalization algorithm as an iterative solver for linear systems with saddle point structure. Such symmetric indefinite…
