The Railway Technical Research Institute (RTRI) in Japan has added more muscle to its supercomputer infrastructure for complex railway simulations. The organization, which focuses on research and development of railway-related science and technology, has deployed a Cray XC30-AC supercomputer, Cray CS300 cluster supercomputer, and a Cray Sonexion storage system into production.
The RTRI’s research spans everything from earthquake cluster prediction to improving the fatigue strength of wheel/axle fittings. The group operates a number of facilities, including a rolling stock test plant; brake test stands that allow for tests up to 500 km/h; a large-scale shaking table to simulate earthquake motion; a station simulator to test passenger flows and thermal/acoustic environments; a rainfall simulator; and a large-scale wind tunnel.
The XC30-AC is the institute’s primary high performance computing system, and will be used to run advanced simulations. The CS300, meanwhile, is used as a general-purpose application server.
The RTRI system has a peak performance of more than 100 teraflops. The Sonexion system includes 220TB of capacity and 10GB per-second of application horsepower.
