TERA-10

TERA-10 is a Supercalculateur French conceived and manufactured by Bull. It belongs to the Direction of the Military Applications of ECA and is with Heathers-the-Châtel. Its startup began with the beginning of the year 2006 and TERA-10 then became one of most powerful the Supercalculateur S of Europe and the seventh with the world.

It is intended for calculations of Simulation S for the development of nuclear weapons. The acquisition of TERA-10 lies within the scope of the program Simulation which already comprises in term of major equipment the radiographic machine Airix and will comprise in the long term the Laser Megajoule (LMJ).

Data-processing simulations are carried out thanks to physical models and mathematical developed by the Commissariat à l'Energie Atomique. The Donnée S used are, on the one hand those acquired during real shootings, in particular those carried out in the Pacific Ocean in 1995 and 1996, and on the other hand those obtained by the radiographic machine Airix during the “cold shootings” carried out on the site of Moronvilliers. The Mégajoule laser will also make it possible to collect experimental Donnée S, in particular on the processes related to the nuclear Fusion implemented in the H-bombs.

Structure:

TERA-10 is powerful a cluster of 602 waiters Bulls NovaScale connected by an interconnected network of very high efficiency Quadrics. The central calculator is made of 544 nodes of calculation made up each one of a waiter Bull NovaScale with 8 processors dual-core Intel Montecito (evolution of the Itanium 2) for a total of 4352 processors (either 8704 hearts). The Supercalculateur has of a central Mémoire of 30 Téraoctet S of RAM and a capacity of Stockage of 1 Pétaoctet distributed on 7.800 discs and accessible with a band-width from 100 Go/s. Tera-10 is largest Supercalculateur using Linux like Operating system (Red Hat distribution adapted and optimized by Bull and ECA).

Computing power:

In November 2006, the performance reached is established with 52.8 téraflops constant according to the classification TOP500, representing nearly 53000 billion operations on floating numbers a second.

The evolution of TERA-10 towards its announced successor, TERA-100, should be accompanied by a rise to power up to 100 téraflops constant in 2009, that is to say approximately 0,6 pétaflops in peak.
