Garrawarla, is a Hewlett-Packard GPU cluster compute system.
“Garrawarla is a 78-node GPU-enabled compute cluster provided by Hewlett-Packard. It is a dedicated system that is available only to Murchison Widefield Array (MWA) radio astronomers.
Garrawarla provides the latest generation of CPUs and GPUs, high memory bandwidth, increased memory, and local storage per node to allow MWA researchers to effectively process petabytes of data streamed from the MWA radio telescope.”

Supercomputers to reflect different workflows and user requirements
Wajarri Yamatji visual artist Margaret Whitehurst produced the artwork for Setonix, inspired by the stars that shine over Wajarri country in Western Australia’s Mid-West.

See MoreThe cabinet artwork on Galaxy, ‘Rainbow Serpent and Moon’ by Jesse Pickett, is a homage to the Centre’s close connection to the northwest of Western Australia. It has been designed to reflect ‘the sky above’, in reference to radioastronomy, one of the areas of science Pawsey closely supports.
