Large-Scale Scientific Computing

The 7th International Conference on Large-Scale Scienti?c Computations (LSSC 2009) was held in Sozopol, Bulgaria, June 4-8, 2009. The conference was organized and sponsored by the Institute for Parallel Processing at the B- garian Academy of Sciences. The conference was devoted to the 70th birthday anniversary of Professor Zahari Zlatev. The Bulgarian Academy of Sciences awarded him the Marin Drinov medal on ribbon for his outstanding results in environmental mat- matics and for his contributions to the Bulgarian mathematical society and the Academy of Sciences. The plenary invited speakers and lectures were: - P. Arbenz, ?Finite Element Analysis of Human Bone Structures - Y. Efendiev, Mixed Multiscale Finite Element Methods Using Limited Global Information - U. Langer, Fast Solvers for Non-Linear Time-Harmonic Problems - T. Manteu?el, First-Order System Least-Squares Approach to Resistive Magnetohydrodynamic Equations - K. Sabelfeld, Stochastic Simulation for Solving Random Boundary Value Problems and Some Applications - F. Tro ¿ltzsch,OnFinite ElementErrorEstimatesforOptimalControlPr- lems with Elliptic PDEs - Z. Zlatev, On Some Stability Properties of the Richardson Extrapolation Applied Together with the ?-method The success of the conference and the present volume in particular are an outcome of the joint e?orts of many partnersfrom various institutions and or- nizations. Firstwe wouldlike to thank allthe membersofthe Scienti?c Comm- tee for their valuable contribution forming the scienti?c face of the conference, as well as for their help in reviewing contributed papers. We especially thank the organizers of the special sessions.
