Cosmology Large Angular Scale Surveyor (CLASS) Focal Plane Development
D. T. Chuss, A. Ali, M. Amiri +28
The Cosmology Large Angular Scale Surveyor (CLASS) will measure the polarization of the Cosmic Microwave Background to search for and characterize the polarized signature of inflat…
Quantifying discordance in the 2015 Planck CMB spectrum
G. E. Addison, Y. Huang, D. J. Watts +4
We examine the internal consistency of the Planck 2015 cosmic microwave background (CMB) temperature anisotropy power spectrum. We show that tension exists between cosmological con…
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…
