Canadian Hydrogen Intensity Mapping Experiment (CHIME) Pathfinder
Kevin Bandura, Graeme E. Addison, Mandana Amiri +31
A pathfinder version of CHIME (the Canadian Hydrogen Intensity Mapping Experiment) is currently being commissioned at the Dominion Radio Astrophysical Observatory (DRAO) in Pentict…
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…
Calibrating CHIME, A New Radio Interferometer to Probe Dark Energy
Laura B. Newburgh, Graeme E. Addison, Mandana Amiri +32
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a transit interferometer currently being built at the Dominion Radio Astrophysical Observatory (DRAO) in Penticton, BC…
A GPU-based Correlator X-engine Implemented on the CHIME Pathfinder
Nolan Denman, Mandana Amiri, Kevin Bandura +17
We present the design and implementation of a custom GPU-based compute cluster that provides the correlation X-engine of the CHIME Pathfinder radio telescope. It is among the large…
Holographic Beam Mapping of the CHIME Pathfinder Array
Philippe Berger, Laura B. Newburgh, Mandana Amiri +32
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) Pathfinder radio telescope is currently surveying the northern hemisphere between 400 and 800 MHz. By mapping the large s…
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…
