N-Body Simulations with GADGET-2

2013 15th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing, 2013
In this paper we discuss cosmological N-Body/SPH simulations on parallel computing systems with distributed memory using GADGET-2. GADGET-2 (GAlaxies with Dark matter and Gas intEracT) is a novel cosmological simulation code, written in C++ and publicly available, developed by Volker Springel at the Max-Planck-Institute for Astrophysics in Munchen ...

Simulated Annealing for N-body systems

1994
In this paper we discuss the mapping of the physical problem of 2D crystallization with spherical boundary conditions onto a Simulated Annealing model, and the mapping of this model onto a parallel computer. We discuss some aspects of the finetuning of the simulation code and the overall behaviour, stability and scalability, of our parallel ...

Prototyping N-body simulation in Proteus

Proceedings Sixth International Parallel Processing Symposium, 2003
This paper explores the use of Proteus, an architecture-independent language suitable for prototyping parallel and distributed programs. Proteus is a high-level imperative notation based on sets and sequences with a single construct for the parallel composition of processes communicating through shared memory.

N-body simulations

ACM Transactions on Mathematical Software, 2006
We describe four challenging N-body test problems involving the Sun and planets and use them to compare the performance of nine nonsymplectic and two symplectic integrators. Each problem has a long interval of integration and two have non-Newtonian gravitational interactions.

Actor-Based Scalable Simulation of N-Body Problem

2023
Efficient solutions of the N-body problem make it possible to conduct large-scale physical research on the rules governing our universe. Vast amount of communication needed in order to make each body acquainted with the information on position of other bodies renders the accurate solutions very quickly inefficient and unreasonable.

Distributed Tree Structures for N-Body Simulation

1996
Several particle simulation algorithms, such as the Barnes-Hut [1] and the Fast Multipole method [2], proceed by hierarchically decomposing the simulation space and representing the distribution of the simulated particles in an adaptive tree data structure which varies as the simulation proceeds.
