Magnus, from the Latin for ‘Great’, is a latest-generation Cray XC30 system that hosts high-end supercomputing projects across the entire range of scientific fields supported by iVEC.

Magnus comprises eight compute cabinets, each holding 48 blades, with four nodes per blade. Each compute node hosts two 12-core, Intel Xeon E5-2690V3 “Haswell” processors running at 2.6 GHz, for a total of 35,712 cores, delivering well in excess of 1 Petaflops of computing power. The compute nodes communicate amongst themselves over Cray’s high-speed, low-latency Aries interconnect.

Local storage (also known as the scratch file system) is provided by a three-cabinet Cray Sonexion 1600 Lustre appliance, with a usable capacity of 3PB and a sustained read/write performance of 70 GB/sec.
At the time of writing, Magnus is believed to be the most advanced research supercomputer in the southern hemisphere.

Interesting facts

  • The XC30 is the first Cray series to feature Intel Xeon processors.
  • Internode communications are more than 9,300-times faster than the NBN.
  • Magnus is more than three orders of magnitude more powerful than iVEC’s first terascale supercomputer, named Cognac, which began production in 2005.
  • Approximately 4km of optical and copper cables link Magnus’s processes together, in a Dragonfly topology, for capability-scale computations.
