| Research Abstract |
Large-scale linear systems appear in many application areas and need to be solved. Since this is a very time-consuming step, we need to solve it fast. In this research project, we study Block Krylov algorithms for solving linear systems with multiple right-hand sides. Moreover, we apply Block Krylov algorithms to the parallel eigensolver for speeding-up of the method.
