AdiosStMan: Parallelizing Casacore Table Data System Using Adaptive IO System
Ruonan Wang, Christopher Harris, Andreas Wicenec
In this paper, we investigate the Casacore Table Data System (CTDS) used in the casacore and CASA libraries, and methods to parallelize it. CTDS provides a storage manager plugin m…
Performance Analysis of GPU-Accelerated Filter-Based Source Finding for HI Spectral Line Image Data
Stefan Westerlund, Christopher Harris
Searching for sources of electromagnetic emission in spectral-line radio astronomy interferometric data is a computationally intensive process. Parallel programming techniques and…
A Framework for HI Spectral Source Finding Using Distributed-Memory Supercomputing
Stefan Westerlund, Christopher Harris
The latest generation of radio astronomy interferometers will conduct all sky surveys with data products consisting of petabytes of spectral line data. Traditional approaches to id…
Scaling Radio Astronomy Signal Correlation on Heterogeneous Supercomputers Using Various Data Distribution Methodologies
Ruonan Wang, Christopher Harris
Next generation radio telescopes will require orders of magnitude more computing power to provide a view of the universe with greater sensitivity. In the initial stages of the sign…
Assessing The Accuracy Of Radio Astronomy Source Finding Algorithms
Stefan Westerlund, Christopher Harris, Tobias Westmeier
This work presents a method for determining the accuracy of a source finder algorithm for spectral line radio astronomy data and the Source Finder Accuracy Evaluator (SFAE), a prog…
