High Performance Computing at the HPC²

The HPC² provides substantial high performance computing resources for use by its member centers.

Shadow is a Cray CS300-LC cluster with 4800 Intel Ivy Bridge processor cores and 28,800 Intel Xeon Phi cores. Each node has either 512 GB of RAM (45%), 128 GB of RAM (45%) or 64 GB of RAM (10%) for a system total of 70 TB of RAM. Furthermore, each node is interconnected via FDR InfiniBand (56 Gb/s). Shadow has a peak performance of 593 teraFLOPS (trillion calculations per second). Shadow is the first production system of its kind and uses an innovative cooling system called direct, warm-water cooling, which allows the system to be cooled with water as warm as 104 degrees Fahrenheit (40 degrees Celsius). On the June 2015 TOP500 Supercomputer Sites list, Shadow was ranked as the 143th fastest computer in the world and the 11th most power computer at any academic site in the United States. It was also the 16th most energy efficient supercomputer in the world according to the June 2015 Green500 list.

Talon is a 3072 core cluster composed of 256 IBM iDataPlex nodes, each with two six-core Intel Westmere processors (2.8GHz) and 24 GB of memory (for a total of 6TB). Each of the nodes are diskless. The system uses Voltaire quad data-rate InfiniBand (40Gb/s) for its high performance interconnect as well as gigabit ethernet for data and systems management. Talon has a peak performance of over 34.4 teraFLOPS (trillion calculations per second).

Raptor is a 2048 core cluster composed of 512 Sun Microsystems SunFire X2200 M2 servers, each with two dual-core AMD Opteron 2218 processors (2.6GHz) and 8 GB of memory (for a total of 4TB). All of the compute nodes are diskless. The system uses gigabit ethernet to connect the 32 nodes in each rack together, and 10 GbE to connect the 16 racks to one another. Raptor has a peak performance of over 10.6 teraFLOPS. On the November 2006 Top 500 Supercomputer Sites list, Raptor debuted as the 115th most powerful computer in the world, and the 18th most powerful computer at any academic site in the United States.

In addition to these systems, the HPC² has many smaller x86 Windows and Linux based servers that provide computational services for various groups and individual projects.
