Code Optimization Activities Toward a High Sustained Simulation Performance
Rapid evolutions of HPC systems bring us a high computational capability. However, it is getting harder to exploit the potential of a HPC system due to the increases in system complexity. To create significant scientific and innovative results by numerical simulations using supercomputers, the collaboration of computational scientists and computer scientists is mandatory. In this article, joint research activities and the code optimization supports promoted in Cyberscience Center are introduced.
