Events: 3rd Symposium of the German SIAM Student Chapters


August 28th, 2014
The 3rd Symposium of the German SIAM Student Chapters toke place in Magdeburg on 28.-29. of August 2014. We welcomed guest from the other German SIAM Chapters in Heidelberg and Trier. For the first time, members of the SIAM Chapter in Prag participated to extend the international connections.

CSC News: New article: Model Order Reduction for Systems with Moving Loads


August 5th, 2014
The article "Model Order Reduction for Systems with Moving Loads" by Peter Benner, Norman Lang and Jens Saak has been published at June 28 2014, in De Gruyter Oldenbourg: at-Automatisierungstechnik: volume 62 (7).

Preprint: On the benefits of the LDLT factorization for large-scale differential matrix equation solvers


July 30th, 2014
Norman Lang, Hermann Mena, and Jens Saak present an LDLT based version of the standard low-rank Lyapunov solvers based on ADI or Krylov subspace methods. The method allows us to avoid complex arithmetic for the solution of matrix differential equations via higher order time integration methods, as well as the a priori reduction of the number of columns in the right hand side of the arising algebraic Lyapunov equations inside of the time integration loop.

Preprint: Extending Lyapack for the Solution of Band Lyapunov Equations on Hybrid CPU-GPU Platforms


July 25th, 2014
Peter Benner, Ernesto Dufrechou, Pablo Ezzatti, Enrique S. Quintana-Orti and Alfredo Remon present an extension of the Lyapack library to solve band Lyapunov equations in CPU-GPU platforms. The approach exploits the modular structure in Lyapack, to incorporate a set of tuned routines that exploit the features of the problem and leverage the parallelism of current CPU-GPU platforms.
