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…
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…
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…
A compression scheme for radio data in high performance computing
Kiyoshi Masui, Mandana Amiri, Liam Connor +11
We present a procedure for efficiently compressing astronomical radio data for high performance applications. Integrated, post-correlation data are first passed through a nearly lo…
