Optimizing the Gravitational Tree Algorithm for Many-Core Processors
Tomoyuki Tokuue, Tomoaki Ishiyama
Gravitational -body simulations calculate numerous interactions between particles. The tree algorithm reduces these calculations by constructing a hierarchical oct-tree structur…

Acceleration of the tree method with SIMD instruction set
Tetsushi Kodama, Tomoaki Ishiyama
We have developed a highly-tuned software library that accelerates the calculation of quadrupole terms in the Barnes-Hut tree code by use of a SIMD instruction set on the x86 archi…

GreeM : Massively Parallel TreePM Code for Large Cosmological N-body Simulations
Tomoaki Ishiyama, Toshiyuki Fukushige, Junichiro Makino
In this paper, we describe the implementation and performance of GreeM, a massively parallel TreePM code for large-scale cosmological N-body simulations. GreeM uses a recursive mul…
