Analysing Astronomy Algorithms for GPUs and Beyond
Astronomy depends on ever increasing computing power. Processor clock-rates have plateaued, and increased performance is now appearing in the form of additional processor cores on a single chip. This poses significant challenges to the astronomy software community. Graphics Processing Units (GPUs...Tags: data structures and algorithms, arxiv, mnras, clean, gpu, graphics processing units

Fast Calculation of the Lomb-Scargle Periodogram Using Graphics Processing Units
I introduce a new code for fast calculation of the Lomb-Scargle periodogram, that leverages the computing power of graphics processing units (GPUs). After establishing a background to the newly emergent field of GPU computing, I discuss the code design and narrate the key parts of the source. Ben...Tags: instrumentation and methods for astrophysics, arxiv, apj, gpu, monte-carlo simulation, periodogram

GAMER with out-of-core computation
GAMER is a GPU-accelerated Adaptive-MEsh-Refinement code for astrophysical simulations. In this work, two further extensions of the code are reported. First, we have implemented the MUSCL-Hancock method with the Roe's Riemann solver for the hydrodynamic evolution, by which the accuracy, overall p...Tags: gpu, instrumentation, methods
