A parallel gravitational N-body kernel
Simon Portegies Zwart, Steve McMillan, Derek Groen +3
We describe source code level parallelization for the {\tt kira} direct gravitational -body integrator, the workhorse of the {\tt starlab} production environment for simulating…
High Performance Direct Gravitational N-body Simulations on Graphics Processing Units -- II: An implementation in CUDA
Robert G. Belleman, Jeroen Bedorf, Simon Portegies Zwart
We present the results of gravitational direct -body simulations using the Graphics Processing Unit (GPU) on a commercial NVIDIA GeForce 8800GTX designed for gaming computers. T…
Towards Distributed Petascale Computing
A. G. Hoekstra, S. F. Portegies Zwart, M. Bubak +1
In this chapter we will argue that studying such multi-scale multi-science systems gives rise to inherently hybrid models containing many different algorithms best serviced by diff…
