At the San Diego Supercomputing Centre (SDSC) booth at SC11 we met Rick Wagner who presented simulations of astrophysics that were done on Jaguar and Kraken at Oak Ridge National Laboratory. In the simulation one could see the light of early galaxies that are forming (red shift of 8). The researchers simulated the birth of […]
John Feo is the director of the Center for Adaptive Supercomputer Software (CASS) at the Pacific Northwest Laboratory. John and his team are using a Cray XMT 1 supercomputer since three years to study a large spectrum of applications like graphs algorithms, Dynamic network analysis (DNA), Emerging Subnetwork Patterns, bioinformatics, semantic search, and semantic database […]
Robert (Bob) Techentin is Principal Software Engineer in the Special Purpose Processor Development Group at Mayo Foundation (Rochester, Minnesota). Robert is one of the first users of the new Cray XMT supercomputer specially designed to analyze large amounts of data. The Mayo Clinic is a large clinical practice for medicine and is specialized on medical […]
Ulrich Schättler is working for Germany’s National Meteorological Service, the Deutscher Wetterdienst (DWD). He started at DWD as software engineer. Years ago he has been asked to parallelize the weather forecast model on distributed memory computers. Since then he is getting involved in weather forecasting and operational forecasting. In his actual function he is responsible […]
While the peak performance and energy efficiency of computing hardware are constantly growing, the development of fast scientific software is experiencing an important paradigm shift. Efficient algorithm implementations face rigid constraints about memory layouts, access patterns and FLOP/Byte ratios. Diego Rossinelli (ETH Zurich) discusses the design of wavelet-based adaptive solvers for compressible flow simulations that […]
