Digital Signal Processing using Stream High Performance Computing: A 512-input Broadband Correlator for Radio Astronomy
J. Kocz, L. J Greenhill, B. R. Barsdell +16
A "large-N" correlator that makes use of Field Programmable Gate Arrays and Graphics Processing Units has been deployed as the digital signal processing system for the Long Wavelen…
Optimizing performance per watt on GPUs in High Performance Computing: temperature, frequency and voltage effects
D. C. Price, M. A. Clark, B. R. Barsdell +2
The magnitude of the real-time digital signal processing challenge attached to large radio astronomical antenna arrays motivates use of high performance computing (HPC) systems. Th…
A Scalable Hybrid FPGA/GPU FX Correlator
J. Kocz, L. J. Greenhill, B. R. Barsdell +8
Radio astronomical imaging arrays comprising large numbers of antennas, O(10^2-10^3) have posed a signal processing challenge because of the required O(N^2) cross correlation of si…
