GEOWALL - INTERACTIVE 3D VISUALISATION

GeoWall in use

Numerical simulations models are of constantly growing importance in the Geosciences. Due to increased computing power and improved algorithmics such models tend to deliver an ever increasing amount of data. However, as Richard Hamming put it "the purpose of computing is insight, not numbers!". Thus, the visualisation of simulation results plays a crucial role. [more]

Our segfault system is a Fujitsu-Technology PRIMERGY RX600 S6 machine mainly intended for simulations in the context of computational seismology. It is an Intel Westmere-EX based machine with 40 cores that can run 80 threads (near) simultaneously making use of Intel's hyper-threading technology. [more]



TETHYS - TECTONIC HIGH-PERFORMANCE SIMULATOR

tethys-1.jpg

Between 2006 and 2012 Munich Geophysics operated a 160 core AMD Operaton cluster with a theoretical peak performance of 0.8 TFLOP. The main objective of the cluster was to serve as a tool to perform capacity simulation with numerical models form Geophysics. The cluster was designed for topical computing, i.e. its intended use was limited to a set of certain key applications. [more]



TETHYS-2G
