The first stage of the bullx supercomputers ordered by the French weather forecasting agency has now been installed at Météo-France’s site in Toulouse and will be fully available for production this year.
The Météo-France supercomputer is the first fully installed, equipped with the upcoming Intel® Xeon® E5-2600 v2 processors, based on Ivy Bridge microarchitecture and 22nm manufacturing process. It is also the largest system to rely on the innovative direct liquid cooling technology developed by Bull to lower energy consumption.
Bull and Intel HPC teams have worked closely together to ensure that the new system takes maximum advantage of the architecture of Intel Xeon E5-2600 v2 processors: with a Linpack performance of 500 TFlops, the system achieves an outstanding efficiency rate of 90% without turbo and a very efficient MFlops/Watt ratio.
Damien Déclat, Project Director for Bull, confirms that “Bull and Intel have been working hand in hand for months to deliver this first Intel Xeon E5-2600 v2 processors-based solution to Météo-France., The integration of the new Intel processors within our bullx DLC blades will allow Météo-France users to complete the transition from vector to scalar technology and to run simulations with outstanding performances on this new generation of system. The transition was greatly facilitated by Bull’s expertise in parallel programming*”.
The overall solution consists of 1080 bullx DLC B710 compute nodes, each equipped with 2 Intel® Xeon® E5-2600 v2 processors and 1866MHz memory DIMMs, interconnected by a high performance InfiniBand® FDR network to achieve a peak performance of 560 TFlops.
“Weather and climate modelling demands exceptional performance efficiency from high performance computing systems. The first European system equipped with the future Intel® Xeon® processor E5-2600 v2 uses an advanced liquid cooling system that helps substantially to realize that performance,” said Dr. Rajeeb Hazra, VP GM of the Intel Technical Computing Group. “Close cooperation between Bull and Intel has helped to create innovation that will allow Météo-France to solve its toughest problem at every scale.”
The Méteo-France’s bullx supercomputer benefits from the direct liquid cooling technology developed by Bull. Cooling takes place inside the blade itself, through direct contact between the heat-producing components (processors, memory…) and a cold plate with coolant circulating within it. This enables water at ambient temperature to be used for cooling, boosting energy performance by around 40% compared to traditional Data Centers, despite being just as easy to maintain as common, air-cooled servers.
*The Bull Centre for Excellence in Parallel Programming, created in partnership with Intel, helps HPC users get their codes ready to take advantage of today’s and tomorrow’s ultra-parallel HPC systems. It provides a large portfolio of services, from analysis, consulting, parallelization, to optimization of application codes.
