The International Centre for Radio Astronomy Research (ICRAR)
was founded in 2009 with the express purpose of supporting
Australia's bid for the SKA.

The execution framework provides the control and monitoring environment to execute millions of tasks, consuming and producing millions of data items on many thousands of individual computers.
This is the scale of processing required for every single SKA observation obtained within six to 12 hours.
Professor Wicenec said the novel execution framework of the science data processor is “data activated”, meaning individual data items are wrapped in an active piece of software that automatically triggers the applications needed to process it.
“Whenever a data item is ready, that’s triggering the next task—the task is not running idle, waiting for anything,” he said. Professor An said the prototype was initially run on 500 compute nodes of the supercomputer and then extended to 1000 nodes.

It was the world’s fastest supercomputer from June 2013 until June 2016.
“The most important part is the co-design and co-optimisation of SKA data processing software set and supercomputers such as Tianhe-2, preparing for the faster computers in a few years from now,” Tianhe-2 director Professor Yutong Lu said.

Two supercomputers, one in Cape Town and one in Perth, each
with a speed of 150 petaflops, will process the SKA data stream.
