As publishers establish a greater online presence as well as infrastructure to support the distribution of more varied information, the idea of an executable paper that enables greater interaction has developed. An executable paper provides more information for computational experiments and results than the text, tables, and figures of standard papers.… (More)

R ecord keeping has always been an essential component of science and engineering, but it has become even more so recently. As computers get faster, we perform increasingly complex computa-tions—and as storage gets cheaper, we accumulate larger volumes of data. The complete process, from data acquisition through analysis, is inherently exploratory: users… (More)

We investigate the influence of magnetic fields upon the dynamics of, and resulting gravitational waves from, a binary neutron-star merger in full general relativity coupled to ideal magnetohydrodynamics. We consider two merger scenarios: one where the stars have aligned poloidal magnetic fields and one without. Both mergers result in a strongly… (More)

We model two mergers of orbiting binary neutron stars, the first forming a black hole and the second a differentially rotating neutron star. We extract gravitational waveforms in the wave zone. Comparisons to a post-Newtonian analysis allow us to compute the orbital kinematics, including trajectories and orbital eccentricities. We verify our code by… (More)

We present a parallel nite-diierence algorithm for the solution of the 3D cylindrical Poisson equation. The algorithm is based on a data-transpose technique, in which all computations are performed independently on each node, and all communications are restricted to global 3D data-transposition between nodes. The data-transpose technique aids us in… (More)

Direct volume rendering is an effective method for plotting 3D scientific data, but it's not used as frequently as it could be. Here, the authors summarize direct volume rendering and discuss barriers to taking advantage of this powerful technique. T he use of plotting techniques to comprehend scalar functions is ubiquitous in science and engineering. An… (More)
