Particle Simulator Research Team

Particle-based simulation is now used in many fields of science, from molecular dynamics simulations to cosmological simulations. In particular, particle-based methods for hydrodynamics such as SPH (Smoothed Particle Hydrodynamics) can treat not only fluid but also solids and their deformation and destruction in a uniform way, and are becoming widely used in engineering applications.

Researchers in the field of astrophysics have been working on large-scale parallelization of particle-based simulation since 1980s, and thus the basic concept of parallelization is well matured. However, such knowledge and technique is far from widespread. In addition, techniques of architecture-dependent optimization of particle-based simulations can in principle be shared by researchers of many different fields, but such sharing is yet to happen.

In order to achieve such a sharing of knowledge and techniques, ,-e aim to develop a common framework for the large-scale parallelization of particle-based simulations.
