High performance computing cluster

Use of device

computer simulations and other complex numerical tasks with high demand on computational power, primarily parallelised problems or large-scale parameter studies.

Basic function

using the queueing system SGE, series of calculation problems can be systematically executed; depending on the requirements, calculations can be split up to between more than 1000 processors

Technical specification

IBM iDataPlex Cluster consisting of 84 nodes with 16 processor cores and 64 GB RAM per node (total of 1344 cores and 5376 GB RAM); infiniband network; total computing power: approx. 25 Tflops; operating system: Linux

COMSOL Multiphysics software package

Use of device

modelling/simulation of physical processes (e.g., structural mechanics, thermal effects, eigenfrequency analysis, fluid-structure interaction, coupling of electro-dynamic, thermal, and mechanical effects, contact mechanics)

Basic function

by means of a graphical user interface, real two- and three-dimensional geometries can be modelled and mesheds; physical phenomena can be freely defined and combined on these geometriess; for the most common physical processes predefined equations are provided; boundary conditions and material properties have to be defined; COMSOL provides solvers for linear/non-linear stationary analyses

Technical specification

Windows/Linux software in the latest version; Comsol Multiphysics base package with various toolboxes (add-ons); also runs on the cluster

Simulink software package

Use of device

modelling and simulation of dynamic systems with a small number of degrees of freedom (e.g. single or multiple mass oscillator, stick-slip motion, control systems)

Basic function

generation of abstract models of dynamic systems by means of block diagrams (graphical user interface); simulation of systems by means of numerical solution of the equations of motion (coupled linear or non-linear ordinary differential equations)

Technical specification

Windows/Linux software in the latest version

Matlab software package

Use of device

complex numeric computational tasks (e.g. data analysis and visualisation, optimisation tasks, image analysis, development of algorithms)

Basic function

by means of MATLABs powerful library of numerical algorithms (e.g. for the inversion of matrices, fast fourier transform, spectral analysis, solution of nonlinear systems of equations), complex computational tasks can be realised efficiently; an extensive toolbox for the generation of graphical user interfaces and for high qualitity visualisation of computation results is avaliable; complex calculation processes can be automated by means of scripts

Technical specification
