Accelerating Dedispersion using Many-Core Architectures
Jan Novotný, Karel Adámek, M. A. Clark +2
Astrophysical radio signals are excellent probes of extreme physical processes that emit them. However, to reach Earth, electromagnetic radiation passes through the ionised interst…
Practical Effects of Integrating Temperature with Strang Split Reactions
M. Zingale, M. P. Katz, D. E. Willcox +1
For astrophysical reacting flows, operator splitting is commonly used to couple hydrodynamics and reactions. Each process operates independent of one another, but by staggering the…
The Murchison Widefield Array Correlator
S. M. Ord, B. Crosse, D. Emrich +64
The Murchison Widefield Array (MWA) is a Square Kilometre Array (SKA) Precursor. The telescope is located at the Murchison Radio--astronomy Observatory (MRO) in Western Australia (…
Digital Signal Processing using Stream High Performance Computing: A 512-input Broadband Correlator for Radio Astronomy
J. Kocz, L. J Greenhill, B. R. Barsdell +16
A "large-N" correlator that makes use of Field Programmable Gate Arrays and Graphics Processing Units has been deployed as the digital signal processing system for the Long Wavelen…
