Atos’ BullSequana supercomputer powered by an AMD processor


Unprecedented performance with increased efficiency

Paris, France, September 18, 2019 – Atos, a global leader in digital transformation, today announces that its BullSequana XH2000 supercomputer powered by an AMD EPYC ™ 7H12 series processor set four new world records for server performance.

Thanks to BullSequana’s enhanced direct liquid cooling system and the powerful AMD EPYC 7H12 processor, Atos measurements currently exceed published best results for two-socket nodes on four SPECrate® benchmarks. * In addition, it set a new record for the HPL Linpack Benchmark on an AMD processor EPYC, with% performance increase. ** They measure the performance of hardware systems under compute-intensive workloads based on real-world applications. The BullSequana surpasses previous records *** (records using both AMD and non-AMD processors) for the 5 benchmarks.

The BullSequana XH2000’s enhanced DLC (Direct Liquid Cooling) has been essential in bringing AMD’s 280W EPYC ™ 7H12 processor to its peak performance level. The results showed unprecedented performance for the lowest power consumption of BullSequana. Energy efficiency is a key priority for large data centers when it comes to selecting a supercomputer, as it results in an optimal TCO (Total Cost of Ownership) saving millions over life. of the project.

“We are extremely proud that our BullSequana has achieved these world records. Our unique improved direct liquid cooling system provided the most efficient environment to achieve such performance from the AMD EPYC processor., ” noted Agnès Boudot, Senior Vice President, Head of HPC & Quantum at Atos. “Our BullSequana, equipped with the latest AMD chip, provides our customers with the best performance available for HPC and AI workloads, with an optimized total cost of ownership, to help them exceed the limits of traditional simulation. “

Several clients around the world have already selected the BullSequana supercomputer powered by an AMD EPYC processor for improved computing capacity to overload their workload. This includes French national organization for high performance computing GENCI, the Computer Center for Science (CSC) in Finland, Norwegian national supplier of electronic infrastructure Uninett Sigma2, a major European weather forecasting center and an American multinational consumer goods giant.

“Meeting the processing challenges of the world’s most efficient systems meant creating a solution that lived up to the task, which AMD achieved with the 2sd Generation AMD EPYC processor, ”said Scott Aylor, Corporate Vice President and General Manager, AMD Data Center Solutions. “Together with Atos BullSequana and their own impressive capabilities and customer relationships, we can offer a whole new range of possibilities to meet the processing needs of the modern data center.


* The Standard Performance Evaluation Corporation (SPEC) CPU 2017 benchmark is designed to provide performance metrics that can be used to compare compute-intensive workloads on different computer systems, including SPECspeed 2017 Integer, SPECspeed 2017 Floating Point, SPECrate 2017 Integer and SPECrate 2017 Floating Point.

Atos results – currently under review by the SPEC Committee:

SPECrate®2017_Int_base 692

SPECrate2017®_fp_base 528

SPECrate®2017_en_peak 586
