Tera 100, Europe’s most powerful supercomputer
is powered up for the first time

arrow6The most powerful system ever designed and developed in Europe



May 27, 2010 : The Military Applications Department of the French Atomic Energy Authority (the CEA) and Bull are today announcing that the CEA's new Tera 100 supercomputer has been powered up for the first time. With a theoretical computing power of 1.25 Petaflops, Tera 100 ranks among the three most powerful supercomputers in the world. Tera 100 is vast program involving close co-operation between Bull and the CEA.

The result of a collaborative program between Bull and the CEA which began in 2008, Tera 100 is the first petaflops-scale* supercomputer ever designed and developed in Europe. Its theoretical maximum power of 1.25 Petaflops means it ranks among the three most powerful supercomputers in the world. Tera 100 is destined for the French nuclear weapons simulation program, aimed at guaranteeing the reliability of nuclear deterrent weapons.

Tera 100 was powered up on 26 May 2010, just a few weeks after its installation in March 2010. Tera 100 consists of 4,300 bullx™ S Series servers, the model announced on the market by Bull in April 2010. It features 140,000 Intel® Xeon® 7500 processing cores, 300TB of central memory and a total storage capacity of over 20PB. Its 500GB/sec throughput to the global file system is a world record for a system of this type.

Tera 100 offers exceptional processing capacity. By way of comparison, it can effectively carry out more operations in a single second than the world’s population would be capable of performing in 48 hours if each person completed one operation a second, day and night. Its capacity to transfer information is equivalent to a million people watching high-definition films simultaneously and its storage capacity corresponds to over 25 billion books.

“Tera 100 being powered up represents a significant industrial success,” commented Jean Gonnord, Computer Simulation and IT Project Director at the CEA. “It highlights both the CEA’s and Bull’s expertise in developing ultra high-performance technologies, to the highest level worldwide, and it fully validates the industrial and research partnership that the CEA and Bull have succeeded in developing: a partnership whose outputs will immediately benefit the whole European scientific and industrial community.”

“We are extremely proud of this successful achievement in petaflops-scale systems,” confirmed Philippe Miltin, Vice-President of Bull’s Products and Systems Division. “These kinds of technologies are not only fundamentally important for applications such as those at the CEA, but also for the design of the new generation of ‘computing power plants’ and massive Cloud Computing infrastructures; which is why expertise in petaflops technologies is a major asset for France, and Europe as a whole.”

“Representing the biggest system ever designed around Intel® Xeon® processors, Tera 100 demonstrates the appropriateness of using Intel processors for High-Performance Computing, in terms of cost, power consumption and processing power. We are very proud to be involved in this major project, alongside the CEA and Bull,” commented Kirk Skaugen, Vice-President and Group Data Center General Manager, Intel.

The Tera 100 program is a close collaboration between Bull and the CEA in the design and development of new Extreme Computing technologies.

To meet the CEA’s requirements, the new supercomputer is distinguished by its ability to run a wide spectrum of applications, its effective balancing of computing power and data flows, and its fault tolerance. A true general-purpose high-productivity system, Tera 100 has been developed around Bull architecture and technologies featuring a vast array of open software and the newest generation Intel® Xeon® 7500 processors.

In particular, Bull has provided its expertise in the design and production of high-performance servers, as well as the development of the software needed to run such large-scale systems. The CEA, for its part, provided its know-how in system specification, IT architecture and software development, as well as its in-depth understanding of large-scale Data Center infrastructures. Several hundred very high-level engineers and researchers have been involved in this project.

Compared with Tera 10, which went into production in 2005, Tera 100 is 20 times more powerful, occupies the same floor space and is seven times more energy efficient. A few months after bullx was named as the best supercomputer in the world in the USA, Tera 100 confirms the technological expertise that Bull has built up, as well as the CEA’s in-depth knowledge of complex infrastructures for High-Performance Computing (HPC). The success of Tera 100 also highlights the leading role that architectures based on standard components now play in HPC, especially those combining Intel® Xeon® processors, Linux® system and Open Source software.
