GPU accelerated Hybrid Tree Algorithm for Collision-less N-body Simulations
Tsuyoshi Watanabe, Naohito Nakasato
We propose a hybrid tree algorithm for reducing calculation and communication cost of collision-less N-body simulations. The concept of our algorithm is that we split interaction f…
Astrophysical Particle Simulations on Heterogeneous CPU-GPU Systems
Naohito Nakasato, Go Ogiya, Yohei Miki +2
A heterogeneous CPU-GPU node is getting popular in HPC clusters. We need to rethink algorithms and optimization techniques for such system depending on the relative performance of…
Implementation of a Parallel Tree Method on a GPU
Naohito Nakasato
The kd-tree is a fundamental tool in computer science. Among other applications, the application of kd-tree search (by the tree method) to the fast evaluation of particle interacti…
Oct-tree Method on GPU
N. Nakasato
The kd-tree is a fundamental tool in computer science. Among others, an application of the kd-tree search (oct-tree method) to fast evaluation of particle interactions and neighbor…
Fast Simulations of Gravitational Many-body Problem on RV770 GPU
Kazuki Fujiwara, Naohito Nakasato
The gravitational many-body problem is a problem concerning the movement of bodies, which are interacting through gravity. However, solving the gravitational many-body problem with…
