Abstract

From a computational perspective direct numerical simulation (DNS) of turbulent flows is enormously challenging. A utilization of current high-performance computing (HPC) resources demands a distribution of the problem to a large number of independently acting computing entities which requires communication in between those entities. I present here a suitable approach to overlap communication and computation for fluid mechanics simulations along with a comprehensive scaling study.
