Topaz

Topaz, a commodity Linux cluster, provided by Xenon, which is an extension of Zeus.

Topaz will be suitable for jobs which can take advantage of the advanced GPU capabilities and latest generation InfiniBand infrastructure. GPUs are accelerators which provide huge amounts of compute power but require less electrical power to run in comparison to conventional CPUs.  Topaz will provide users with enhanced GPU capabilities, in particular, AI, computational work, machine learning workflows and data analytics.

Galaxy

The 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.

Magnus

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.
