A GPU Spatial Processing System for CHIME
Nolan Denman, Andre Renard, Keith Vanderlinde +4
We present an overview of the Graphics Processing Unit (GPU) based spatial processing system created for the Canadian Hydrogen Intensity Mapping Experiment (CHIME). The design empl…
Spectral Kurtosis Based RFI Mitigation for CHIME
Jacob Taylor, Nolan Denman, Kevin Bandura +5
We present the implementation of a spectral kurtosis based Radio Frequency Interference detection system on the CHIME instrument and its reduced-scale pathfinder. Our implementatio…
The CHIME Fast Radio Burst Project: System Overview
FRB Collaboration, M. Amiri, K. Bandura +49
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a novel transit radio telescope operating across the 400-800-MHz band. CHIME is comprised of four 20-m x 100-m semi-cy…
GPU Kernels for High-Speed 4-Bit Astrophysical Data Processing
Peter Klages, Kevin Bandura, Nolan Denman +3
Interferometric radio telescopes often rely on computationally expensive O(N^2) correlation calculations; fortunately these computations map well to massively parallel accelerators…
An Efficient Real-time Data Pipeline for the CHIME Pathfinder Radio Telescope X-Engine
Andre Recnik, Kevin Bandura, Nolan Denman +5
The CHIME Pathfinder is a new interferometric radio telescope that uses a hybrid FPGA/GPU FX correlator. The GPU-based X-engine of this correlator processes over 819 Gb/s of 4+4-bi…
