This book constitutes the thoroughly refereed post-proceedings of the 5th International Conference on Large-Scale Scientific Computations, LSSC 2005, held in Sozopol, Bulgaria in June 2005.

The 75 revised full papers presented together with 5 invited papers were carefully reviewed and selected for inclusion in the book. The papers are organized in topical sections on advances in computational mechanics and multi physics, robust algebraic multigrid and hierarchical preconditioning methods, monte carlo: tools, applications, distributed computing, control systems, uncertain systems, operator splitting, their application and realization, distributed numerical methods and algorithms for grid computing, environmental modelling, large scale computation of engineering problems, and numerical methods for the Schr?dinger equation and application.
