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…
Cutting the cost of pulsar astronomy: Saving time and energy when searching for binary pulsars using NVIDIA GPUs
Jack White, Karel Adamek, Wes Armour
Using the Fourier Domain Acceleration Search (FDAS) method to search for binary pulsars is a computationally costly process. Next generation radio telescopes will have to perform F…
Bits missing: Finding exotic pulsars using bfloat16 on NVIDIA GPUs
Jack White, Karel Adamek, Jayanta Roy +3
The Fourier Domain Acceleration Search (FDAS) is an effective technique for detecting faint binary pulsars in large radio astronomy datasets. This paper quantifies the sensitivity…
Implementation of 3D degridding algorithm on the NVIDIA GPUs using CUDA
Karel Adámek, Peter Wortmann, Bojan Nikolic +2
Practical aperture synthesis imaging algorithms work by iterating between estimating the sky brightness distribution and a comparison of a prediction based on this estimate with th…
Implementing CUDA Streams into AstroAccelerate -- A Case Study
Jan Novotný, Karel Adámek, Wes Armour
To be able to run tasks asynchronously on NVIDIA GPUs a programmer must explicitly implement asynchronous execution in their code using the syntax of CUDA streams. Streams allow a…
Efficiency Near the Edge: Increasing the Energy Efficiency of FFTs on GPUs for Real-time Edge Computing
Karel Adámek, Jan Novotný, Jeyarajan Thiyagalingam +1
The Square Kilometre Array (SKA) is an international initiative for developing the world's largest radio telescope with a total collecting area of over a million square meters. The…
