The SKALB project (Lattice-Boltzmann methods for scalable multiphysics applications) aims at efficiently implementing and the development of Lattice-Boltzmann based CFD solvers for the simulation of complex multiphysics applications on petascale class computers. The project partners are scientists from the universities of Erlangen-Nuremberg, Dortmund, Stuttgart and Braunschweig, additionally IANUS Simulation GmbH is an industrial partner. SKALB is supported by numerous industrial partners from Germany and abroad.

Apart from specific issues concerning CFD solvers, SKALB also deals with interdisciplinary of petascale computing topics. As an example the following two topics are relevant in this context:

• Sustainable software structures for the efficient numerical simulation on petascale class computers.
• Development of efficient strategies of parallelization and optimization for massive parallel homogeneous and heterogeneous architectures.

SKALB is third-party funded within the BMBF initiative "HPC software for scalable parallel computers " with a budget of 1,8 Mio EUR for the years 2009 to 2011.
