Journal ArticleDOI
Dark halos formed via dissipationless collapse. I: Shapes and alignment of angular momentum
TL;DR: In this article, the structure and kinematics of the largest relaxed halos in each of 10 separate simulations were analyzed using N-body simulations on highly parallel supercomputers to study the structure of Galactic dark matter halos.
Journal ArticleDOI
Automatic Creation of Object Hierarchies for Ray Tracing
Jeffrey Goldsmith,John K. Salmon +1 more
TL;DR: This work presents methods for evaluation of these trees in approximate number of intersection calculations required and for automatic generation of good trees in O(nlogn) expected time where n is the number of objects in the scene.
Proceedings ArticleDOI
A parallel hashed oct-tree N-body algorithm
Michael S. Warren,John K. Salmon +1 more
TL;DR: The authors report on an efficient adaptive N-body method which computes the forces on an arbitrary distribution of bodies in a time which scales as N log N with the particle number.
Patent
Configurable adaptive global traffic control and management
Paul E. Stolorz,John K. Salmon,Michael S. Warren,Jeffrey G. Koller,Aric Hagberg,Maksim Yevmenkin,Mark Brady,David Pfitzner,Ted Middleton +8 more
TL;DR: In this article, the authors propose a policy-based domain name service, where the domain name server resolves the hostname to at least one address corresponding a server in the subscriber server network based on a policy consideration such as geographic policies, load share policies, overflow policies, and network aware policies.
Journal ArticleDOI
Skeletons from the treecode closet
John K. Salmon,Michael S. Warren +1 more
TL;DR: It is found that the conventional Barnes-Hut MAC can introduce potentially unbounded errors unless θ 3 , and that this behavior while rare, is demonstrable in astrophysically reasonable examples.
