Advancing the SKA Science Data Processing Design towards the Critical Design Review

After a design phase of almost 5 years the SKA consortia are amidst their Critical Design Reviews (CDR). One of the most challenging elements is the Science Data Processor (SDP), that takes the correlated signal of the interferometric antenna array at a rate of 400+ GB/s and generates approx. 100 PB of science ready data products per year. There will be two arrays located in Australian and South Africa effectively doubling those rates and contributing to a federated pool of storage and compute services across a global network of Regional Centres. This talk gives a status of the SKA project, the SDP architecture and design methodology. It will highlight the crucial role of Australian institutions in scaling precursor systems and provide examples and opportunities for co-design efforts with commercial partners.


Juan Carlos Guzman is the Head of the Software and Computing Group at CSIRO Astronomy and Space Science. Over the past 11 years he has been involved in the design, development and integration of the data flow software systems for the Australian SKA Pathfinder (ASKAP) radio telescope, located in Western Australia. ASKAP is a precursor of the SKA, the world’s next generation astronomical telescope, and one of the first instruments to incorporate High Performance Computing (HPC) infrastructure as part of its routine operations. Juan Carlos is regarded internationally as an expert on software design and development for astronomical instruments. He plays a key role in the software design for the international SKA project and is a member of various advisory and conference committees. Juan Carlos is based in Perth, Australia and enjoys working with colleagues in international collaborations as well as mentoring and training the next generation of computing engineers.


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.
