A slow-down time-transformed symplectic integrator for solving the few-body problem
Long Wang, Keigo Nitadori, Junichiro Makino
An accurate and efficient method dealing with the few-body dynamics is important for simulating collisional N-body systems like star clusters and to follow the formation and evolut…
Accelerated FDPS --- Algorithms to Use Accelerators with FDPS
Masaki Iwasawa, Daisuke Namekata, Keigo Nitadori +4
In this paper, we describe the algorithms we implemented in FDPS to make efficient use of accelerator hardware such as GPGPUs. We have developed FDPS to make it possible for many r…
Implementation and Performance of Barnes-Hut N-body algorithm on Extreme-scale Heterogeneous Many-core Architectures
Masaki Iwasawa, Daisuke Namekata, Ryo Sakamoto +9
In this paper, we report the implementation and measured performance of our extreme-scale global simulation code on Sunway TaihuLight and two PEZY-SC2 systems: Shoubu System B and…
Fortran interface layer of the framework for developing particle simulator FDPS
Daisuke Namekata, Masaki Iwasawa, Keigo Nitadori +6
Numerical simulations based on particle methods have been widely used in various fields including astrophysics. To date, simulation softwares have been developed by individual rese…
