COPA-GT Workshop on HPC

The COPA-GT Workshop on HPC was held from 11 to 12 July at JSC as part of the EU Initial Training Network "Coupled Parallel Simulation of Gas Turbines" (COPA-GT), providing training in high-performance computing for young researchers from the fields of propulsion and electric power generation systems. The COPA-GT network has 10 participating member organizations and is coordinated by the Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique (CERFACS), see http://copagt.cerfacs.fr/.

The goal of the workshop was to achieve higher performance of the flow solvers used within the COPA-GT network. Although the participants had only limited prior experience with the BG/Q architecture, with the help of JSC staff members all the codes (ALYA, DELTA, Moose, OpenFOAM and ZFS) were successfully ported to JUQUEEN, and the majority of them were scaled up to two racks (32,000 cores). The tuned codes will help to improve the modelling of gas turbines, paving the way for cleaner combustion process and lower CO₂ emissions, one of the central scientific aims of COPA-GT.
