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…
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…
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…
