Eviden, the advanced computing brand of the Atos Group, has launched its next-generation supercomputing platform designed for the converging demands of artificial intelligence and high-performance computing. The BullSequana XH3500 is engineered to scale beyond exascale performance, providing a comprehensive ecosystem of hardware, software, and services to accelerate scientific and industrial innovation.
Eviden launches the BullSequana XH3500 supercomputer for converged HPC and AI workloads.
The platform is designed for exascale performance with enhanced energy efficiency and scalability.
It delivers over 80% more power and 30% greater cooling capacity in the same rack footprint.
A modular, open design prevents vendor lock-in and allows custom CPU, GPU, and accelerator configurations.
The system features 100% fan-less direct liquid cooling for reduced TCO and heat reuse.
It aims to accelerate scientific discovery and AI-driven breakthroughs for research and industry.
The BullSequana XH3500 represents a significant leap in performance density and energy efficiency. Compared to its predecessor, it delivers over 80% more electrical power per square meter and a 30% increase in cooling capacity within the same rack footprint. This allows organizations to meet growing computational demands without expanding their data center space, thereby reducing cooling power requirements and overall environmental impact. The system's 100% fan-less fifth-generation Direct Liquid Cooling supports warm water, enabling significant total cost of ownership (TCO) reductions and facilitating heat reuse strategies.
A key differentiator of the BullSequana XH3500 is its unparalleled flexibility. Its open, modular design allows customers to mix and match different computing, acceleration, and networking technologies to create configurations tailored to specific needs, from complex simulation to large-scale AI training. This approach eliminates vendor lock-in, ensures technology freedom, allows for the seamless integration of future processors, and protects long-term investments.
The platform is at the center of a broader, integrated ecosystem that brings together software, services, and expert support. This cohesive framework is designed to accelerate time-to-value by helping organizations deploy and optimize their HPC-AI investments effectively. Complementary software tools provide intelligent power and resource management, dynamically optimizing performance and energy use in real-time.
Bruno Lecointe, VP, global head of HPC, AI and Quantum Computing at Eviden, Atos Group, said “The convergence of HPC and AI is redefining how we solve the world’s most complex challenges. Our mission is to accompany our customers throughout the entire lifecycle, accelerating applications, reducing time-to-solution, and maximizing the value and impact of their HPC-AI investments.”
Addison Snell, CEO of Intersect360 Research, highlighted “The BullSequana XH3500 addresses the top needs cited by users in our surveys, to bring AI capabilities to scientific and technical applications while still maintaining a focus on high-performance computing. Importantly, Eviden does this without locking into one vendor’s roadmap, which allows organizations to maintain flexibility and adapt quickly to innovation.”
The launch of the BullSequana XH3500 solidifies Eviden's position at the forefront of the AI-HPC convergence. By delivering a powerful, efficient, and flexible platform, Eviden provides the foundational technology for organizations to navigate the evolving computational landscape and tackle tomorrow's most complex challenges.
