Abstract

The Building-Cube Method (BCM) has been proposed as a new CFD method for an efficient three-dimensional flow simulation on large-scale supercomputing systems, and is based on equally-spaced Cartesian meshes. As a flow domain can be divided into equally-partitioned cells due to the equally-spaced meshes, the flow computations can be divided to partial computations of the same computational cost. To achieve a high sustained performance, architecture-aware implementations and optimizations considering characteristics of supercomputing systems are essential because there have been various types of supercomputing systems such as a scalar type, a vector type, and an accelerator type. This paper discusses the architecture-aware implementations and optimizations for various supercomputing systems such as an Intel Nehalem-EP cluster, an Intel Nehalem-EX cluster, Fujitsu FX-1, Hitachi SR16000 M1, NEC SX-9, and a GPU cluster, and analyses their sustained performance for BCM. The performance analysis shows that memory and network capabilities largely affect the performance of BCM rather than computational potentials.
