RECSY - A High Performance Library for Sylvester-Type Matrix Equations

In this presentation, we give an overview of research activities at the Department of Computing Science, Ume˚a University with focus on Scientific, Parallel and High-Performance Computing. The first part of the talk will give a brief general overview. The second part will illustrate some of the current research directions of my students, myself and colleagues. I plan to review some recent results in the following areas. – Recursive Blocked Algorithms and Hybrid Data Structures for Dense Matrix Library Software (with Erik Elmroth, Fred Gustavson, and Isak Jonsson, see SIAM Review, Vol. 46, No. 1, 2004, pp. 3-45.) – Matrix Equations (with Robert Granat and Isak Jonsson) • RECSY - A high performance library for Sylvester-type matrix equations • ScaLAPACK-style algorithms and software for Sylvester-type matrix equations – Parallel, Blocked and Multishift Variants of the QZ Algorithm for Regular Matrix Pairs (with Bj¨orn Adlerborn and Daniel Kressner, TU-Berlin) – Robust Co...
