ASTRONOMY

The Institute of Fluid Science, Tohoku University is a unique research facility that specializes in fluid science -- the flow of material substance as well as heat, energy and information. As a pioneer, the institute has achieved a number of findings by conducting large-scale numerical simulations essential to fluid science research. The institute selected SGI Japan's proposal for its cost-effective system that met all the requirements for the new supercomputer and for SGI's extensive experience and a number of achievements in the supercomputing field in Japan. The new supercomputer, shipped this summer, is comprised of a scalable SGI Altix 3000 scalar parallel server based on the 64-bit Linux OS, a vector parallel NEC computer, a scalable Silicon Graphics Prism visualization system, external secondary storage systems and data archive systems, all of which are interconnected via high-speed network, enabling sharing of large files with the SGI InfiniteStorage CXFS shared filesystem and the NEC GFS global file system attached to the Storage Area Network (SAN). The core of the new system is one of the fastest computers to have been installed in Japan for fluid science researches. Based on the SGI Altix system, the supercomputer will contain 1,024 Intel Itanium 2 processors and 12TB (terabytes) of main memory in a large-scale shared-memory configuration, or single system image (SSI). The Institute of Fluid Science has installed a Silicon Graphics Prism visualization system -- one of the most powerful visualization systems in the world -- with 256 processors, eight ATI graphics processors and 2TB of main memory that will be used to accelerate the analysis of results generated on the Altix system. The new system will also provide 1PB (Petabyte) of storage, one of the largest storage systems in Japan. In April, 2003, the institute expanded by establishing a next-generation Fluid Integration Research Center where scientists promote fluid science researches in various advanced science and engineering fields by means of a new research methodology integrating its experimental and computational methods. To analyze and control increasingly complex and diversified fluid problems, the institute decided to replace its existing supercomputer with a new system specifically designed for-next generation fluid integration research for even more accurate results and shorter time to solution. The institute also needs to enhance its interface server and visualization server for real-time integration of experimental and simulation results and 3D visualization to solve complex flow problems seen in actual phenomena through its new methodology. The Silicon Graphics Prism system will be used to understand the results generated by the next generation of fluid simulations. The institute will also use SGI's Visual Area Networking technology to deliver interactive, visual results directly to researchers' desktops independent of their location. The disk and tape storage systems will respectively provide a large capacity of 1PB sufficient to process and store massive research data. By connecting both the supercomputers and visualization system to the SAN based on CXFS, researchers will be able to share one set of storage for their entire research process. This accelerates fluid research by eliminating time consuming data copies and simplifying storage management.
