New Algorithms for Exascale Computing
Workshop at University of Cologne
December 04 - 06, 2013, Cologne, Germany
This workshop will address algorithmic, programming and application software aspects for the simulation of complex multiscale problems on the future supercomputers for exascale computing. It is organized within and funded by the German Priority Program 1648 "Software for Exascale Computing" (SPPEXA) by the Deutsche Forschungsgemeinschaft (DFG). Multiscale problems appear in different SPPEXA projects, e.g., the simulation of high strength steels in EXASTEEL or the simulation of flow in environmental or technical porous media in EXA-DUNE. ESSEX develops exascale sparse eigensolvers for studies of graphene-based structures, topological insulators, and quantum Hall effect devices. There is a common need for efficient computational homogenization schemes and highly scalable and robust preconditioners on the basis of algebraic multigrid and domain decomposition methods. In this workshop we plan to bring together internationally known experts from these fields of research with researchers from the projects ESSEX, EXA-DUNE, EXASTEEL, ExaStencils, and TerraNeo. The workshop will be also open for other projects from SPPEXA as well as for researchers from outside the priority program.
