The project ASIL (Advanced Solvers Integrated Library) is concerned with the development of efficient and robust solution methods for large linear systems and of an associated software library.
Solving large linear systems is one of the main tasks in the simulation of phenomena from natural sciences, engineering, life science, finance, economics, and technology, as this step determines the complexity of the whole simulation process. Thus, the availability of highly scalable as well as efficient and robust solvers is of crucial relevance for usability of high performance parallel computers.
The development is realized in the kernel of the solution process of large systems. Filtering algebraic multigrid methods are improved and combined with H-matrix techniques for that reason. At the same time, we will develop and realize methods for further problems like multiscale, eigenvalue or optimization problems. Thus, a new software library for the solution of very large problems will be available at the end of the project ASIL.
The ASIL project is a cooperation between our group, Prof. Dr. G. Wittum at Goethe Center for Scientific Computing, Prof.Dr. W. Hackbusch at the Max-Planck-Institute for Mathematics in the Sciences in Leipzig, Prof. Dr. V. Schulz at the University of Trier, and Prof. Dr. C. Wieners the Institut für Wissenschaftliches Rechnen und Mathematische Modellierung (IWRMM) at the Karlsruhe Institute of Technology, and Prof.Dr. M. Resch at the High performance Computing Center Stuttgart
