NVIDIA Powers Europe’s Fastest Supercomputer With Game-Changing Grace Hopper Platform

NVIDIA Powers Europe’s Fastest Supercomputer: In June 2025, NVIDIA made history by powering Europe’s fastest supercomputer, JUPITER, with its revolutionary Grace Hopper platform. This breakthrough is more than just a technological marvel—it’s a catalyst for scientific discovery, industrial innovation, and a greener digital future.

But what sets JUPITER apart from other supercomputers, and why is the Grace Hopper platform such a game-changer for Europe and the world? Let’s explore these questions in detail, using clear language and real-world examples that make sense to everyone, from curious students to professional researchers.

NVIDIA Powers Europe’s Fastest Supercomputer

The launch of JUPITER, powered by the NVIDIA Grace Hopper platform, marks a new chapter for European science, industry, and innovation. With unmatched speed, world-leading energy efficiency, and the ability to solve problems once thought impossible, JUPITER is set to accelerate breakthroughs in climate science, medicine, engineering, and beyond. Whether you’re a student, a researcher, or a business leader, JUPITER offers the tools and opportunities to shape the future—one calculation at a time.

What Is JUPITER and Why Is It Important?

JUPITER is Europe’s first exascale supercomputer. In simple terms, this means it can perform more than a quintillion (1,000,000,000,000,000,000) calculations per second. For context, if everyone on Earth performed one calculation per second, it would take over four years to do what JUPITER can do in a single second.

Why Exascale Matters

• Scientific Discovery: Exascale computing allows scientists to simulate complex systems—like the Earth’s climate, the human brain, or the formation of galaxies—with far greater detail and accuracy.
• Artificial Intelligence (AI): JUPITER can train and run massive AI models, making it possible to solve problems that were previously out of reach.
• Industrial Innovation: Companies can use JUPITER to design safer cars, develop new materials, and optimize manufacturing processes—all in a virtual environment.

The Grace Hopper Platform: JUPITER’s Supercharged Engine

At the heart of JUPITER is the NVIDIA Grace Hopper Superchip (GH200), which combines a powerful CPU (Grace) and GPU (Hopper) into one tightly integrated unit.

What Makes the Grace Hopper Platform Revolutionary?

• Unified Memory: The CPU and GPU share memory, allowing data to move quickly and efficiently between them. This reduces bottlenecks and speeds up complex calculations.
• High Bandwidth: Each superchip offers up to 500 GB/s of memory bandwidth, enabling rapid access to large datasets.
• Energy Efficiency: The GH200 is designed to deliver maximum performance per watt, making JUPITER one of the greenest supercomputers ever built.
• Scalability: With nearly 24,000 GH200 superchips, JUPITER can handle the largest and most complex workloads in Europe.

How JUPITER Works: Architecture and Design

JUPITER is a modular supercomputer, meaning it’s built from many smaller units (modules) that work together as one powerful system. This design allows for flexibility, scalability, and efficient maintenance.

The Two Main Modules

1. Booster Module

• Purpose: Handles the most demanding calculations, especially those needed for AI and simulations.
• Specs: Around 6,000 nodes, each with four GH200 superchips.
• Performance: Delivers 1 exaflop/s for scientific computing and over 70 exaflops for AI tasks.
• Networking: Uses high-speed InfiniBand technology to connect nodes, ensuring fast communication and data transfer.

2. Cluster Module

• Purpose: Complements the booster by handling tasks that require lots of memory or different types of processing.
• Specs: Over 1,300 nodes, powered by European-designed processors.
• Special Feature: Extra-high memory bandwidth for data-heavy workloads, such as genomics or fluid dynamics.

Energy and Sustainability

JUPITER is not just about raw power—it’s also about responsibility. The system uses advanced liquid cooling to keep temperatures down and recycles waste heat to warm nearby buildings. This approach reduces its environmental footprint and sets a new benchmark for sustainable computing.
