An Integrated Procedure for Tree-Nbody Simulations: FLY and AstroMD
U. Becciani, V. Antonuccio-Delogu, F. Buonomo +1
We present a code allowing to evolve three-dimensional self-gravitating collisionless systems with a large number of particles N >= 10^7. FLY (Fast Level-based N-bodY code) is a fu…
AstroMD. A multi-dimensional data analysis tool for astrophysical simulations
U. Becciani, V. Antonuccio-Delogu, C. Gheller +3
Over the past few years, the role of visualization for scientific purpose has grown up enormously. Astronomy makes an extended use of visualization techniques to analyze data, and…
Structural properties of Dark Matter Halos
V. Antonuccio-Delogu, U. Becciani, A. Pagliaro
Using the results of a high mass resolution ( particles) N-body simulation of a cluster-forming region, we study the statistic for low mass halos (${\rm M} < 10^…
Capanic: A Parallel Tree N-Body Code for Inhomogeneous Clusters of Processors
V. Antonuccio-Delogu, U. Becciani
We have implemented a parallel version of the Barnes-Hut 3-D N-body tree algorithm under PVM 3.2.5, adopting an SPMD paradigm. We parallelize the problem by decomposing the physica…
