Efficient channelization on a Graphics Processing Unit
Bruce Merry
We present an implementation of a channelizer (F-engine) running on a Graphics Processing Unit (GPU). While not the first GPU implementation of a channelizer, we have put significa…
Tricolour: an optimized SumThreshold flagger for MeerKAT
Benjamin V. Hugo, Simon Perkins, Bruce Merry +2
We present Tricolour, a package for Radio Frequency Interference mitigation of wideband finely channelized MeerKAT correlation data. The MeerKAT passband is heavily affected by int…
Inflation of 430-parsec bipolar radio bubbles in the Galactic Centre by an energetic event
I. Heywood, F. Camilo, W. D. Cotton +96
The Galactic Centre contains a supermassive black hole with a mass of 4 million suns within an environment that differs markedly from that of the Galactic disk. While the black hol…
Faster GPU-based convolutional gridding via thread coarsening
Bruce Merry
Convolutional gridding is a processor-intensive step in interferometric imaging. While it is possible to use graphics processing units (GPUs) to accelerate this operation, existing…
A Performance Comparison of Sort and Scan Libraries for GPUs
Bruce Merry
Sorting and scanning are two fundamental primitives for constructing highly parallel algorithms. A number of libraries now provide implementations of these primitives for GPUs, but…
Approximating W projection as a separable kernel
Bruce Merry
W projection is a commonly-used approach to allow interferometric imaging to be accelerated by Fast Fourier Transforms (FFTs), but it can require a huge amount of storage for convo…
