Accelerate application performance

The performance of exascale applications requires massive parallelism. Bull sequana integrates the Bull Exascale Interconnect (BXI) network, developed by Bull. Designed for exascale, BXI revolutionizes the treatment of data exchanges by freeing the processors of all communications tasks. In addition, the Bull sequana software environment allows a precise management of large resources and provides optimum production efficiency.

Deliver a resilient platform

An exaflops-scale supercomputer includes tens of thousands of components. Such a system must incorporate high quality resilience. The architecture and packaging of Bull sequana were designed with this objective in mind, including the redundancy of critical components, and efficient software suite and management tools.

Provide unique know-how to  customers

From design to operational use, Bull sequana supercomputers integrate cutting-edge technologies. Real Formula 1 IT, they offer the highest levels of performance, quality, robustness and flexibility.  
Bull sequana is the result of technological partnerships (1) and of many cooperation (2) within the European HPC ecosystem (3). Bull sequana, which will be delivered in 2015, with a general availability from Q3 2016, is a major milestone on the road to exascale.

For François Geleznikoff, Director of CEA military applications, commented:  "CEA is pleased to get this year the first prototype of the exascale supercomputer planned for 2020. This is our third generation of supercomputer supplied by Bull, which allows us to perform with great speed and reliability both physical modeling and very complex systems calculations.”

"GENCI welcome the Bull sequana exascale class supercomputers that will help researchers meet the major challenges of the 21st century in societal areas such as health, environment and new energy. In order to best prepare the French scientific communities to this next generation of supercomputers, GENCI has established a collaboration with Bull and Intel to evaluate the potential of these technologies and their suitability for a representative set of scientific applications of the major themes of the research," said Catherine Rivière, CEO of GENCI.

"Science is endless.

November 18, 2014 - Bull takes the lead in the extreme computing race

En route to processing power that rivals the human brain

  • The next generation of supercomputers is required to boost innovation and competitiveness and address a multitude of challenges – most of them at the crossroads where Big Data and HPC meet – related to every aspect of society, including healthcare, climatology, manufacturing and energy.
  • So-called exascale supercomputers will achieve a performance of more than one billion billion operations a second (the number 1 followed by 18 zeroes): a thousand times more powerful than current systems.
  • Bull is rolling out its exascale program, so it’s ready to meet the technical challenges involving in ultra-fast computing of massive datasets on an unprecedented scale.
  • Bull is designing and developing its next generation of supercomputers in Europe, drawing on the power and presence of the Atos Group to deliver exascale solutions in key vertical market sectors all over the world.

Bull, an Atos company, today unveils its exascale program. The main ambition of this program is to design and develop in Europe the next generation of supercomputers that will contribute to producing world-class solutions for both research and industrial purposes. With one of the largest teams dedicated to High-Performance Computing (HPC) – now able to leverage the international strength of Atos, with its 86,000 employees worldwide – Bull is experiencing a paradigm shift that will give it the critical mass to address vertical market sectors across the entire world.

Exascale will increase the competitiveness and innovation capabilities of industries and address the industrial, scientific and societal challenges of the 2020s, from nanoscience and genomics to climatology, aeronautics and energy.

As such, the Bull exascale program is a key contributor to Europe’s leadership in science and innovation, as well to its position in the HPC field. It is aligned with the Strategic Research Agenda proposed by ETP4HPC (the European Technology Platform for High Performance Computing). This new generation of supercomputers will be capable of achieving a performance of more than one exaflops, i.e. one billion billion operations a second, a thousand times more powerful than current systems. Exascale computing power is believed to be the order of processing power that matches the human brain.


Most of the complex problems scientists and engineers will address in the future are at the crossroads where Big Data meets HPC. For instance, domains like genomic therapy and drug discovery, full-scale simulations of aircraft or modelling of entire weather systems – that involve huge volumes of data and demand massive computing power – require exascale supercomputers and beyond.

The Bull exascale program therefore relies on tight integration between high levels of computing power and the capacity to process huge amount of data. It combines faster processors, more data capacity, ultra-fast interconnections, greater energy efficiency, enhanced cooling, a scalable packaging, fundamentally redesigned software and a full set of services to optimize user applications.

The Bull exascale program initially involves the development of five main elements:

  • An open exascale supercomputer, code-named SEQUANA
  • The matching software stack, known as bullx supercomputer suite
  • A new generation of fast interconnect, code-named BXI
  • A range of servers with ultra-high memory capacity, known as the bullx S6000 series
  • A complete set of services to optimize customer applications and make the most of exascale.

The Bull exascale program derives synergies from Bull’s global mission to deliver Big Data, HPC and security solutions. It is the result of major investments in R&D, close cooperation with European labs such as the CEA (the French Alternative Energies and Atomic Energy Authority) and other partners, and the long-standing experience built up by Bull’s HPC teams in designing, implementing and running large-scale HPC systems. It relies upon the Bull Center for Excellence in Parallel Programming (CEPP) for the application expertise needed to reengineer existing applications so as to make the most of exascale systems.

To fulfill its missions, the French Alternative Energies and Atomic Energy Commission (CEA) set up a R&D program in partnership with industry which aims at developing the key technologies needed to design and build competitive supercomputers by 2020. Within this framework, CEA and Bull have renewed their long-time partnership that led in 2010 to the first petaflops supercomputer designed and manufactured in Europe,” said Pierre Leca, Head of Simulation and Software Engineering at the CEA.

With the unveiling of its exascale program, Bull has reaffirmed its capacity for innovation and its ability to design the world's most powerful supercomputers. Bull meets the needs of performance and reliability that our customers require to handle the massive amounts of data generated in the digital world and to help solve major societal and environmental challenges that are arising in our societies,” said Philippe Vannier, Bull’s CEO.

The Bull exascale program in detail

November 17, 2014 - OCCIGEN: Pushing the frontiers of science and technology

With its new large scale supercomputer called OCCIGEN (pronounced oxygen), GENCI, the French HPC agency, provides French scientists with a great boost of the global capacity available and makes a technological leap toward energy efficiency with Bull and Intel.

GENCI, the French HPC agency, has acquired in June 2014 a new 2.1 Pflops large scale supercomputer called OCCIGEN (pronounced oxygen). This Bull system is installed at the National Computer Center for Higher Education (Cines, Centre informatique national de l'enseignement supérieur), one of the three national computing centers in France.

It multiplies by more than 8 times the computing resources available at Cines and allows GENCI to provide French scientists with a great boost of the global capacity available reaching a total of 5.7 Pflops.
Addressing any kind of simulation

OCCIGEN is powered by the 12 cores Intel® Xeon® E5-2690 v3 processor, for a total amount of 50 000 cores and its balanced architecture includes more than 200 TB of distributed memory and an I/O subsystem able to manage data at a speed of over 100GB/s, using Intel supported Lustre*.

Thanks to this performance, OCCIGEN will be capable of addressing any type of numerical simulation and managing massive amounts of data. It is also designed to subsequently accommodate hybrid technologies.
Presented at ISC in June, this supercomputer powered by the new Intel Xeon E5-2600 v3 product family is a powerful solution for the HPC community,” said Charles Wuischpard, vice president Data Center Group and general manager of Workstations and HPC, Intel. “The Intel Xeon E5-2690 v3 processor chosen by GENCI for OCCIGEN, offers Top 500 class performance and energy efficiency for the French academic community. This program is part of a long term collaboration between GENCI, Bull and Intel, and a first step to highly parallel workload.

Going green
Bull, an Atos company, has been selected after an open and highly competitive tendering process, including a considerable focus on energy optimization for simulations and financial assessment taking into account the total cost of ownership of the supercomputer over its entire expected lifespan.

Based on the direct liquid cooled bullx B720 compute blades, the OCCIGEN supercomputer has a peak compute performance in excess of 2 PFlops (2 million billion floating point operations per second), implementing the new Intel AVX2 instruction set, thanks to its Intel® Xeon® Processors E5-2690 v3 Family (code-named Haswell-EP). OCCIGEN reached a « Linpack » performance of more than
1.628 Pflops, thus demonstrating an efficiency rate of 97% of the AVX2 performance per compute node, and of more than 78% of the global system peak performance.

"OCCIGEN is therefore positioned as one of the most energy-efficient x86 supercomputers (global consumption of 975kW, i.e. 1,670 Mflops/W per node) and is an outstanding addition to the HPCG list of bullx supercomputers with a performance of 45474.6 GFlops. It is now one of the most efficient HPC systems both in terms of performance and energy-efficiency, and a key asset for French digital simulation and research” declared Pascal Barbolosi, VP Extreme Computing at Bull, an Atos company.

World premieres expected
OCCIGEN is aimed to address the needs of French scientists by performing massive 3D multi-scale, multi-physics complex simulations and managing huge amount of data generated by large-scale instruments or numerical simulations.

And, as a first and great result, OCCIGEN has already demonstrated its performances on real scientific key applications with impressive improvements of more than 20% for SPECFEM3D (geophysics) and up to 274% for YALES2 (combustion), in comparison with GENCI current petascale systems.

OCCIGEN will be in full production for all French scientists in January 2015 but is already open in pre-production mode for performing “Grands Challenges” including world premiere in climate modeling, massive LES simulation of wind turbines or brain modeling.

Our priority is to give to French scientists the means to be in a good position in the international scientific community, by making the best resources available for them, while minimizing the environmental impact. With OCCIGEN, the latest of our supercomputers to be installed, GENCI has completely revamped French computing resources, but is also firmly committed to an eco-responsible approach. The expected OCCIGEN performance will pave the way to great scientific achievements in all fields. ” Catherine Riviere, CEO of GENCI, said.
