24.77 Pflops on a Gravitational Tree-Code to Simulate the Milky Way Galaxy with 18600 GPUs
Jeroen Bédorf, Evghenii Gaburov, Michiko S. Fujii +3
We have simulated, for the first time, the long term evolution of the Milky Way Galaxy using 51 billion particles on the Swiss Piz Daint supercomputer with our -body gravitation…
The cosmic web in CosmoGrid void regions
Steven Rieder, Rien van de Weygaert, Marius Cautun +2
We study the formation and evolution of the cosmic web, using the high-resolution CosmoGrid $Λ$CDM simulation. In particular, we investigate the evolution of the large-scale stru…
Computational Gravitational Dynamics with Modern Numerical Accelerators
Simon Portegies Zwart, Jeroen Bédorf
We review the recent optimizations of gravitational -body kernels for running them on graphics processing units (GPUs), on single hosts and massive parallel platforms. For each…
On the Effects of Subvirial Initial Conditions and the Birth Temperature of R136
Daniel Caputo, Nathan de Vries, Simon Portegies Zwart
We investigate the effect of different initial virial temperatures, Q, on the dynamics of star clusters. We find that the virial temperature has a strong effect on many aspects of…
Star Formation in the vicinity of Nuclear Black Holes: Young Stellar Objects close to Sgr A*
B. Jalali, F. I. Pelupessy, A. Eckart +6
It is often assumed that the strong gravitational field of a super-massive black hole disrupts an adjacent molecular cloud preventing classical star formation in the deep potential…
A connected component-based method for efficiently integrating multiscale -body systems
Jürgen Jänes, Federico I. Pelupessy, Simon F. Portegies Zwart
We present a novel method for efficient direct integration of gravitational N-body systems with a large variation in characteristic time scales. The method is based on a recursive…
