Computing Overview of the HPC²
The HPC² provides substantial high performance computing resources for use by its member centers, including a 593 TeraFLOPS cluster with 4800 Intel Ivy Bridge processor cores and 28,800 Intel Xeon Phi cores, 70 terabytes of main memory, 4 terabytes of Xeon Phi memory, and an FDR InfiniBand interconnect; a 34 TeraFLOPS 3072-core Intel Westmere cluster with 6 terabytes of RAM and quad data-rate InfiniBand interconnect; a 10 TeraFLOPS 2048-core AMD Opteron cluster with 4 terabytes of RAM; and a small Cray XT5 for applications development. Data storage capabilities include 4.5 petabytes of high performance RAID-enabled disk systems including a large parallel file system, and a 9 petabyte near-line storage/archival system. The HPC2 advanced scientific visualization needs are met by an immersive CAVE-like virtual reality environment, dubbed the Virtual Environment for Real Time EXploration or VERTEX.
The HPC² network infrastructure backbone consists primarily of a 10-Gigabit Ethernet network interconnecting the organization's primary computing and storage systems, as well as an extensive number of edge switches providing connectivity to the desktops. Each of the three HPC² facilities obtains external network connectivity to the commodity Internet and Internet2 through dual 10 Gigabit/sec connections into the Mississippi Optical Network (MISSION), a regional optical network supporting research activities within the state.
