Atos launches the BullSequana XH3000 AI HPC supercomputer

Stepping deeper into the era of exascale AI, Atos gave a first look at its next-generation high-performance computer.

The BullSequana XH3000 combines Atos’ patented fourth-generation liquid-cooled HPC design with NVIDIA technologies to deliver both more performance and power efficiency.

Offering users a choice of Arm or x86 computer architectures, it will be available in versions using NVIDIA Grace, Intel, AMD or SiPearl processors. For accelerated computing, it supports nodes with four NVIDIA Tensor Core GPUs.

The XH3000 also flexibly uses network options including NVIDIA Quantum-2 InfiniBand and NVIDIA ConnectX-7 InfiniBand and Ethernet adapters to scale these powerful compute nodes into HPC systems capable of 10 exaflops of mixed-precision AI.

HPC + AI + quantum hybrid system

The result is a flexible, hybrid computing platform capable of running the most demanding HPC simulations, AI works, and even emerging quantum computing workloads.

The BullSequana XH3000 “will undoubtedly enable, via the exascale gateway, some of the key advances in scientific and industrial innovation of the future”, said Rodolphe Belmer, CEO of Atos, during a virtual event revealing the system.

With customers in over 70 countries, Atos is the No. 1 in supercomputing in Europe, India and South America and particularly recognized in France, where it has its headquarters as well as a manufacturing and R&D base.

A broad collaboration

Optimizations for the XH3000 were among the first projects of EXAIL, the joint AI lab of excellence that Atos and NVIDIA announced in November.

John Josephakis, global vice president of sales and business development for HPC/supercomputing at NVIDIA, praised the team behind the system in a video message.

“By combining Atos’ well-known expertise with NVIDIA AI and HPC technologies and work in our joint lab, this platform will enable researchers to gain meaningful insights much faster on grand challenges both in supercomputing and industrial HPC,” he said.

EXAIL’s work spans climate research, health and genomics, quantum computing, advanced artificial intelligence/computer vision, and cybersecurity. Its researchers can access application frameworks such as NVIDIA Clara for health and NVIDIA Morpheus for security, as well as the NVIDIA cuQuantum SDK for quantum computing and the NVIDIA HPC SDK that runs hundreds of scientific and techniques.

A long and productive relationship

Atos has built one of the first European supercomputers to use the NVIDIA Ampere architecture, the JUWELS Booster, at the Jülich Supercomputing Center. It uses 3,744 NVIDIA A100 Tensor Core GPUs to deliver 2.5 exaflops of mixed-precision AI performance.

To better understand climate change, Atos and NVIDIA researchers will run AI models on the system, currently ranked No. 8 on the TOP500 list of the world’s fastest supercomputers. Julich researchers used the system in April to perform state-of-the-art quantum circuit simulation.

Last year, Atos led the deployment of BerzeLiUs, a system based on the NVIDIA DGX SuperPOD and Sweden’s largest supercomputer. The company also provided supercomputing infrastructure in Europe, India and South America based on NVIDIA DGX systems.

Then, Atos builds Leonardo, a supercomputer from the Italian inter-university consortium CINECA. It will ship 14,000 NVIDIA A100 GPUs on an NVIDIA Quantum InfiniBand network and is expected to become the world’s fastest AI supercomputer capable of 10 exaflops of mixed-precision AI performance.

With the first look at the BullSequana XH3000, it’s clear there’s a lot more to come from Atos and NVIDIA’s collaboration.
