A Real-time Single Pulse Detection Algorithm for GPUs

Understand

The detection of non-repeating events in the radio spectrum has become an important area of study in radio astronomy over the last decade due to the discovery of fast radio bursts (FRBs).

• We have implemented a single pulse detection algorithm, for NVIDIA GPUs, which use boxcar filters of varying widths.
• Our code performs the calculation of standard deviation, matched filtering by using boxcar filters and thresholding based on the signal-to-noise ratio.
• We present our parallel implementation of our single pulse detection algorithm.
