The First Star-by-star -body/Hydrodynamics Simulation of Our Galaxy Coupling with a Surrogate Model
Keiya Hirashima, Michiko S. Fujii, Takayuki R. Saitoh +9
A major goal of computational astrophysics is to simulate the Milky Way Galaxy with sufficient resolution down to individual stars. However, the scaling fails due to some small-sca…
SCF-FDPS: A Fast -body Code for Simulating Disk-halo Systems
Shunsuke Hozumi, Keigo Nitadori, Masaki Iwasawa
A fast -body code has been developed for simulating a stellar disk embedded in a live dark matter halo. In generating its Poisson solver, a self-consistent field (SCF) code whic…
PeTar: a high-performance N-body code for modeling massive collisional stellar systems
Long Wang, Masaki Iwasawa, Keigo Nitadori +1
The numerical simulations of massive collisional stellar systems, such as globular clusters (GCs), are very time-consuming. Until now, only a few realistic million-body simulations…
Particle-particle Particle-tree Code for Planetary System Formation with Individual Cut-off Method: GPLUM
Yota Ishigaki, Junko Kominami, Junichiro Makino +2
In a standard theory of the formation of the planets in our Solar System, terrestrial planets and cores of gas giants are formed through accretion of kilometer-sized objects (plane…
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…
