Tech & Innovation : Atos/Bull

home page return


With Atos’ Bull sequana, a supercomputer, France could be leading the world in another high-tech sector. Bull sequana was presented by Atos Chairman and CEO Thierry Breton to industry executives and researchers in Paris this April 2016. By 2020, Bull sequana will reach exaflops level of computing, that is processing a billion billion operations per second. Compared to current petaflops-scale systems, this will offer 1000 times more performance, 10 times more energy-efficiency and take 10 times less space. Atos’ Bull has besides developed its own complex 5 billion-transistors-chip to enable supercomputer microprocessors used in parallel to interconnect, whatever processor or memory brand is used.

For Atos, this will be a leap forward to challenge for world leadership in exascale-class supercomputers. France which is in competition with the US, China and Japan chose to develop supercomputers rather than PCs more than 50 years ago.

Increasing computational power with exceptional levels of data processing is becoming essential for competitiveness in industry and research. It enables quality and speed of modelling and simulation in sectors like aeronautics, motor industry, personalized medicine, precision agriculture, meteorology etc. In France companies and institutions like Safran for aircraft engines, Renault, Dassault, L’Oréal, CEA (French Atomic Energy and Alternative Energies Commission) use Bull supercomputers. French SMEs and Midcaps would also be using supercomputers to steal a march on their competitors. In Germany, the French supercomputers’ predictive capabilities are used by DKRZ, the meteorological research center.

According to research firm IDC, the world market for supercomputers reached $11.3 billion in 2015, with a predicted annual growth rate of 7.5%. The stakes are therefore high for Atos’ Bull as more countries and foreign companies could decide to use French supercomputer technology in future.
