Earth Simulator Achieves Top LINPACK Efficiency

Japan's top sustained performance also achieved

TOKYO, June 4 -- NEC Corporation today announced that the renewed Earth Simulator System, which NEC deployed for the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), an independent administrative organization, on March 1, 2009, achieved sustained performance of 122.4 TFLOPS and computing efficiency of 93.38% on the LINPACK benchmark.

The system secured Japan's No.1 sustained performance position (No.16 worldwide) and achieved the world's top position in terms of computing efficiency according to the "TOP500 Supercomputing Sites," published in November 2008.

The renewed Earth Simulator System is a large-scale vector supercomputer that consists of 160 nodes of NEC's SX-9/E and boasts peak performance of 131 TFLOPS. This vector supercomputer is equipped with a high performance CPU (102.4 GFLOPS), which is ranked the world's fastest CPU currently operating. The system's scores were achieved through large-scale shared memory, high speed data transfer between the CPU and memory, and an ultra high speed network connecting nodes, in addition to the CPU's performance.

The performance of the renewed Earth Simulator System enables greater accuracy and understanding in the provision of advanced warnings for complex phenomenon that include global warming, air and ocean pollution, the El Nino effect, severe rainfall, hurricane movement forecasts and others. The system is also expected to contribute to greater Japanese economic activity, the resolution of environmental issues and the understanding of changes in the Earth's crust and earthquake occurrences.

Looking forward, NEC will continue to strengthen the development of advanced performance vector supercomputers while also providing customers with optimal systems through scalar supercomputers and PC cluster systems.

NVIDIA Works On CPU Co-Dependency Issues with Kepler GPU

NVIDIA is telling everyone that the GK110, its new Kepler GPU aimed at supercomputing, is all about improving performance per watt. But the other driving theme behind the new architecture is reducing the GPU's reliance on its CPU host. How well it accomplishes both these goals areas could determine the success of the new chip in high performance computing.
