Magnus, from the Latin ‘Great’, is a latest-generation Cray XC30 system that will be used for supercomputing projects across the entire range of scientific fields serviced by iVEC. Magnus currently comprises two compute cabinets, each holding 52 compute blades, with four nodes per blade and each node supporting two 8-core Intel Sandy Bridge Xeon E5-2670 processors running at 2.6 GHz, for a total of 3328 cores delivering around 69 TFLOPS. The compute nodes communicate amongst themselves over Cray’s high-speed, low-latency Aries interconnect. Storage consists of two petabytes of scratch file system space, provided by Cray’s Sonexion Lustre appliances, and is connected via 56 Gbit/s FDR Infiniband.

Magnus will be expanded in Q3 2014 with additional cabinets and processors that will see the Pawsey Centre become a petascale supercomputing facility, delivering processing power in excess of a petaflop (one quadrillion floating point operations per second). The final configuration of Magnus will provide users with over 35,000 cores, using the future Intel® Xeon® processor E5-2600 v3 product family (former codename Haswell), and it is expected to be the most powerful supercomputer in the southern hemisphere.
