Computation Resources
Since January 2004, gSupercomputer System for Statistical Scienceh has been in operation and has analyzed a large volume of statistical data. The main components of this system comprise a SGI Altix3700 Super Cluster (a parallel computer system with 256 Itanium2 processors and about 2 TB main memory), a NEC SX-6 (a vector-type computer system with 12 vector processors and 128 GB main memory), and a HITACHI SR11000 (a parallel computer sub-system with 64 Power4+ processors and 128 GB main memory). In January 2006, gSystem for Computational Statisticsh was renewed. The main components of this system consist of a HP XC4000 Cluster system with 256 Opteron processors for computing node and 640 GB main memory, a SGI Prism visualization system with 16 Itanium2 processors and 32 GB main memory, and a large display system (Multi Opt View). In December 1998, an Ethernet network using 1000Base-SX as a main trunk and 100Base-TX as branches was laid out as a Local Area Network. Workstations, personal computers in researchersf offices, gSupercomputer System for Statistical Scienceh, and gSystem for Computational Statisticsh were all connected to the network. This Local Area Network enables distributed processing and computation resources and statistical data to be used effectively. The development of programs, which run on gSupercomputer System for Statistical Scienceh and on gSystem for Computational Statisticsh by operating from workstations and personal computers in researchersf offices, is also underway. To encourage joint research with researchers both in Japan and abroad, as well as the exchange of e-mails, the network is connected to the internet through SINET. The connection speed of 1.5 Mbps during FY 1999 has risen to 100 Mbps since July 2002. Since April 2007, the network has also been connected to the SINET3 with 2.4 Gbps bandwidth. Some machines are able to communicate at a rate of 1 Gbps. Through terminal servers, the network is also accessible from a public line. In addition, comprehensive network security measures have been implemented such as the adoption of anti-virus software as well as a network monitoring system.( As of April 1, 2007 )
