performance advantage for such bandwidth-limited kernels. Compact application versions of the new Coarray based particle movement algorithms are extracted from the fusion application and evaluated on the worlds largest HPC platform with PGAS enabled hardware (Cray XE6) and on a Cray XT4 without hardware
HPC Benchmarking and Performance Evaluation With Realistic Applications
"... The goal of benchmarking and performance evaluation, as viewed in this paper, is to assess the performance and understand characteristics of HPC platforms and their important applications. An obvious use of the gained results is the search for machines that are best for a given purpose. Equally impo ..."

HPC for Large Scale CFD in Aircraft Design
"... Abstract. In aircraft development the aerodynamic design is a long lead item. To reduce the development time advanced flow modeling methods must be used earlier than today. This is however limited by the current turn around time for the simulations. To reduce the turn around time the computer platfo ..."
