TeraFlops Computing with the Hitachi SR8000-F1: From Vision to RealityThese proceedings are concerned with results from scientific investigations obtained with calculations done on the Hitachi SR8000-F1 supercomputer at Leibniz Computing Center. The following contribution gives an overview of the innovative Hitachi architecture and the configuration of the machine at LRZ.

A User-Oriented Set of Quantum Chemical BenchmarksUsers of our computing centres recurrently asked for comparisons of the machine performance for different quantum chemical programs. They are also interested in the scalability of parallel codes.

Large-Eddy and Detached-Eddy Simulation of the Flow Around High-Lift Configurationsfigurations large-eddy simulations (LES) were carried out. Additionally, the flow past an infinitely thin plate was simulated by detached-eddy simulation (DES). First a relatively low chord Reynolds number .. = 20, 000 was chosen for the airfoil case yielding a leading-edge stall for both angles of

Direct Simulation with the Lattice Boltzmann Code BEST of Developed Turbulence in Channel Flowsensive venture in view of the high memory and CPU time requirements. Today, the DNS is limited to very low Reynolds number and simple flow geometries which are far away from technical relevance. Therefore, there is an increasing demand in the development of numerical schemes to simulate fluid flows

This technique is implemented in the code MGLET, a parallel Cartesian Navier-Stokes solver for DNS and LES which uses second-order central space and time discretizations and fractional time-stepping together with an iterative solver for the p
