Each XC30 cabinet will provide 66 teraflops (or 66 trillion floating-point operations per second) and can be aggregated into a system offering more than 100 PFLOPS (petaFLOPS, or thousand trillion floating point operations per second). Each cabinet will consist of three chassis, with each chassis having 16 computer blades, and each blade comprising four nodes. The system can be built with as many as 92,544 nodes, each with up to 128GB of DDR3 memory.
Cray will initially use Intel Xeon E5-2600 processors for the system. Eventually, XC systems will also be able to use Intel Xeon Phi co-processors and Nvidia Tesla GPUs, which are based on the next-generation Kepler architecture.
The XC supercomputers also feature a novel form of cooling, one that uses both air and water, and that does not require the system to be set up in a hot aisle/cold aisle configuration.
The systems will run the Cray Linux Environment, a software package that includes the Linux operating-system kernel, the Lustre file system, support for the Chapel parallel programming language, and SLURM (Simple Linux Utility for Resource Management).
Cray has already sold six XC30s, to organizations such as the Swiss National Supercomputing Centre, the Finnish IT Center for Science, the Department of Energy's National Energy Research Scientific Computing Center and the University of Stuttgart's High Performance Computing Center in Germany.
