"Our goal for the new high-performance computing system is to enhance our ability to produce highly reliable numerical weather forecasts and develop and run numerical models of the ocean and atmosphere for climate assessment," said Peter Aakjaer, director general of DMI. "The extreme scalability and unprecedented sustained performance of the Cray XT5 supercomputer will allow us to run an operational weather forecast with more than 10 times the calculations and I/O throughput than we can with our current system. This will enable us to better safeguard human life and property, and provide a foundation for economic and environmental planning throughout the vast geographical area of Denmark, the Faroes and Greenland, which is a significant part of the North Atlantic and Arctic region."

Cray announced its next generation of supercomputers -- the Cray XT5 family -- on November 6, 2007. Incorporating all the benefits of the successful Cray XT(TM) line, the Cray XT5 massively parallel processor (MPP) system includes a new compute blade that quadruples local memory capacity, doubles processor density and improves energy efficiency for a significant reduction in total cost of ownership for customers.

"We are very excited that DMI selected the Cray XT5 system for its operational weather forecasts and climate studies," said Peter Ungaro, president and CEO of Cray. "DMI's challenging computing requirements are the perfect match for the unprecedented sustained application performance, reliability, exceptional manageability and lower cost of ownership the Cray XT5 system offers customers. We are proud that DMI will use the world's most scalable Linux-based supercomputer to meet their goals and continue to provide internationally acclaimed meteorological services."

The DMI contract, including future services and maintenance, is valued at approximately EUR 6 million.

About DMI

The Danish Meteorological Institute is one of the major organizations within the newly established Danish Ministry of Climate and Energy. Serving the needs of society, including Danish Defence and civil aviation, the core activities of DMI are weather and ocean forecasting and climate change assessment. The basis for DMI's central production is advanced numerical modeling which requires still more powerful computer systems in order to utilize the latest scientific achievements.
