Japan's Railway Technical Research Institute Puts Multiple Cray Supercomputers Into Production

SEATTLE, WA -- (Marketwired) -- 09/05/13 -- Global supercomputer leader Cray Inc. (NASDAQ: CRAY) today announced that the Railway Technical Research Institute (RTRI) in Japan has put a Cray XC30-AC supercomputer, a Cray CS300 cluster supercomputer and a Cray Sonexion storage system into production. Researchers and engineers at RTRI combined the Cray CS300 cluster supercomputer and the Cray XC30-AC supercomputer into one virtual system performing complex simulations aimed at advancing railway technologies.

Based in Tokyo, RTRI is a railway research organization with focused research and development efforts that are intended to bring new innovations to railway-related science and technology. RTRI's new Cray XC30-AC supercomputer is the Institute's primary high performance computing system, and is providing its researchers and engineers with a powerful tool for running the advanced supercomputer-based simulations that are vitally important to RTRI. The Cray CS300 system functions as a general-purpose applications server for the Institute.

"High performance computing is a critical element of our R&D initiatives, and after a series of reviews to determine the next-generation supercomputing solution to be the successor to our current system, we once again turned to Cray," said Hideyuki Takai, Executive Director of RTRI. "The flexibility, reliability, scalability and power efficiency of the Cray supercomputing systems played an important role in our decision, and we are pleased that our researchers and engineers will continue to have the computational tools necessary for performing our daily R&D activities."

"The Cray XC30-AC and the CS300 cluster supercomputer are complimentary systems, and the approach RTRI has taken is compelling. By combining both products into one supercomputing system, RTRI has created a price/performance solution that best meets the needs of their applications," said Mamoru Nakano, president of Cray Japan. "RTRI is one of our company's long-standing commercial customers in Japan, and we are pleased that through our collaborative relationship, the Institute will continue to apply the computational power of Cray supercomputers towards the development of new railway technologies."

The Cray supercomputing system at RTRI has a peak performance of more than 100 teraflops, and the Cray Sonexion scale-out Lustre system includes 220 terabytes of capacity and 10 gigabytes per-second of applications performance.
