Demonstration of control and processing software for the ASKAP telescope

1Csiro, Epping, Australia


In this presentation we demonstrate various aspects of the software systems used for the Australian Square Kilometre Array Pathfinder (ASKAP) telescope. This telescope is characterised by very large data rates, by virtue of its novel phased-array feed receivers, and it required specific solutions for the operation, control & monitoring, and data processing that were able to handle the large numbers of hardware elements and large data volumes. We will demonstrate software elements used to prepare and execute observations, and monitor their progress. The processing of observations on the galaxy supercomputer at the Pawsey Supercomputing Centre will be demonstrated, along with examples of the data products produced. And finally the CSIRO ASKAP Science Data Archive (CASDA), the repository of ASKAP observations and the go-to place for scientists to access data products will be demonstrated.


Matthew Whiting is acting Group Leader for ATNF Science, part of CSIRO Astronomy & Space Science, leading a group responsible for research and science operations within the Australia Telescope National Facility. He has a PhD in astrophysics from University of Melbourne, and a career of working in astronomy and astronomical computing. Matthew leads the development of the processing pipelines for CSIRO’s ASKAP telescope, and is a member of the small software team responsible for the high-performance calibration & imaging software for ASKAP. He is also the sole developer of the widely-used Duchamp source-finding software, designed for 3D astronomical spectral-line surveys. He works closely with the Pawsey Supercomputing Centre, and is a member of Astronomy Australia Limited’s Astronomy e-Research Advisory Committee.


AeRO is the industry association focused on eResearch in Australasia. We play a critical coordination role for our members, who are actively transforming research via Information Technology. Organisations join AeRO to advance their own capabilities and services, to collaborate and to network with peers. AeRO believes researchers and the sector significantly benefit from greater communication, coordination and sharing among the increasingly different and evolving service providers.
