Interesting facts

  • Aggregate internode communications are over 100,000 gigabits per second – which is the same as the combined speed of every household in Australia being connected to the average National Broadband Network plan simultaneously.
  • Magnus is more than three orders of magnitude more powerful than the Pawsey Supercomputing Centre’s first terascale supercomputer, named Cognac, which began production in 2005.
  • At the time of writing, Magnus is the most powerful public research supercomputer in the Southern Hemisphere. It debuted at #41 on the November 2014 Global Top500 list of supercomputers. In the most recent June 2015 Top500 list, it was ranked at #58.
  • Approximately 4km of optical and copper cables link Magnus’s processors together, in a Dragonfly topology, for capability-scale computations.
  • The cabinet artwork on Magnus, ‘SKA Satellites on the Murchison’ by Margaret Whitehurst, is an 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.
  • In November 2014, Magnus was also ranked at #77 in the world’s Green500 most energy efficient supercomputers, with 1,573.56 MegaFLOPS per Watt.
