A development of an accelerator board dedicated for multi-precision arithmetic operations and its application to Feynman loop integrals II
H Daisaka, N Nakasato, T Ishikawa +2
Evaluation of a wide variety of Feynman diagrams with multi-loop integrals and physical parameters and its comparison with high energy experiments are expected to investigate new p…
Hierarchical Tree Algorithm for Collisional N-body Simulations on GRAPE
Toshiyuki Fukushige, Atsushi Kawai
We present an implementation of the hierarchical tree algorithm on the individual timestep algorithm (the Hermite scheme) for collisional -body simulations, running on GRAPE-9 s…
A development of an accelerator board dedicated for multi-precision arithmetic operations and its application to Feynman loop integrals
Shinji Motoki, Hiroshi Daisaka, Naohito Nakasato +5
Higher order corrections in perturbative quantum field theory are required for precise theoretical analysis to investigate new physics beyond the Standard Model. This indicates tha…
GRAPE-6A: A single-card GRAPE-6 for parallel PC-GRAPE cluster system
Toshiyuki Fukushige, Junichiro Makino, Atsushi Kawai
In this paper, we describe the design and performance of GRAPE-6A, a special-purpose computer for gravitational many-body simulations. It was designed to be used with a PC cluster,…
Pseudoparticle Multipole Method: A Simple Method to Implement High-Accuracy Treecode
Atsushi Kawai, Junichiro Makino
In this letter we describe the pseudoparticle multipole method (P2M2), a new method to express multipole expansion by a distribution of pseudoparticles. We can use this distributio…
Structure of Dark Matter Halos From Hierarchical Clustering
Toshiyuki Fukushige, Junichiro Makino
We investigate the structure of the dark matter halo formed in the cold dark matter scenario using -body simulations. We simulated 12 halos with the mass of $6.6\times 10^{11}M_…
