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…
Subparsec-scale dynamics of a dusty gas disk exposed to anisotropic AGN radiation with frequency-dependent radiative transfer
Daisuke Namekata, Masayuki Umemura
We explore the gas dynamics near the dust sublimation radius of active galactic nucleus (AGN). For the purpose, we perform axisymmetric radiation hydrodynamic simulations of a dust…
On the evolution of gas clouds exposed to AGN radiation. I. Three-dimensional radiation hydrodynamic simulations
Daisuke Namekata, Masayuki Umemura, Kenji Hasegawa
We perform three-dimensional radiation hydrodynamic simulations of uniform dusty gas clouds irradiated by an active galactic nucleus (AGN) to investigate the dependence of evolutio…
Mass Supply to Galactic Center due to Nested Bars in the Galaxy
Daisuke Namekata, Asao Habe, Hidenori Matsui +1
We investigate rapid mass supply process by nested bars in the Galaxy by numerical simulation. We simulate gas flow in the whole galaxy disk with nested bars, which are the outer b…
