Our petascale supercomputer, Magnus (Latin for ‘Great’), is the only public access research Cray XC40 in Australia.  Magnus has been designed specifically to tackle the largest simulations currently possible, at previously unimaginable resolutions. 

It currently provides high-end computing capability to projects across the entire spectrum of scientific fields.  Magnus provides a software stack highly attuned to its hardware, allowing researchers to solve data simulations faster and more easily.

The cabinet artwork on Magnus, ‘SKA Satellites on the Murchison’ by Margaret Whitehurst, is a homage to the Centre’s close connection to the north-west of Western Australia. It has been designed to reflect ‘the ground below’, in reference to geoscience, one of the areas of science the Pawsey Supercomputing Centre supports most closely.
