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…
Searching for pulsars in extreme orbits -- GPU acceleration of the Fourier domain 'jerk' search
Karel Adámek, Jan Novotný, Sofia Dimoudi +1
Binary pulsars are an important target for radio surveys because they present a natural laboratory for a wide range of astrophysics for example testing general relativity, includin…
GPU Fast Convolution via the Overlap-and-Save Method in Shared Memory
Karel Adámek, Sofia Dimoudi, Mike Giles +1
We present an implementation of the overlap-and-save method, a method for the convolution of very long signals with short response functions, which is tailored to GPUs. We have imp…
A GPU implementation of the Correlation Technique for Real-time Fourier Domain Pulsar Acceleration Searches
Sofia Dimoudi, Karel Adamek, Prabu Thiagaraj +3
The study of binary pulsars enables tests of general relativity. Orbital motion in binary systems causes the apparent pulsar spin frequency to drift, reducing the sensitivity of pe…
Improved Acceleration of the GPU Fourier Domain Acceleration Search Algorithm
Karel Adámek, Sofia Dimoudi, Mike Giles +1
We present an improvement of our implementation of the Correlation Technique for the Fourier Domain Acceleration Search (FDAS) algorithm on Graphics Processor Units (GPUs) (Dimoudi…
Pulsar Acceleration Searches on the GPU for the Square Kilometre Array
Sofia Dimoudi, Wesley Armour
Pulsar acceleration searches are methods for recovering signals from radio telescopes, that may otherwise be lost due to the effect of orbital acceleration in binary systems. The v…
