Germany’s LRZ to Launch “Blue Lion” Supercomputer Powered by NVIDIA’s Vera Rubin Architecture
The Leibniz Supercomputing Centre (LRZ) in Germany is preparing to unveil its next-generation high-performance computing system — Blue Lion — a supercomputer projected to deliver 30 times the computing power of its current flagship system, SuperMUC-NG.For some time, LRZ, a member of the Gauss Centre for Supercomputing, had only hinted that its next system would utilize next-generation NVIDIA accelerators and processors. Now, it’s confirmed: Blue Lion will be built on NVIDIA’s upcoming Vera Rubin architecture.
This marks one of the first public deployments of Vera Rubin, following closely behind Doudna, a next-generation supercomputer announced by the Lawrence Berkeley National Laboratory in the U.S. Both systems, on separate continents, will harness the same advanced architecture — signaling a major step forward for global AI and scientific computing.
What Is NVIDIA Vera Rubin?
Vera Rubin is a breakthrough computing platform that unifies AI, data analysis, and simulation workloads. It’s powered by a new superchip combining:
- Rubin GPU – the next-generation successor to NVIDIA’s Blackwell GPUs
- Vera CPU – NVIDIA’s first custom-designed CPU, optimized to operate seamlessly with the Rubin GPU
This tightly integrated platform delivers high bandwidth, low latency, and coherent memory sharing, aiming to dramatically accelerate scientific discovery. With in-network acceleration and a unified architecture, Vera Rubin is purpose-built to meet the evolving demands of AI-driven research.
Germany’s Leibniz Supercomputing Centre, LRZ, is gaining a new supercomputer that delivers roughly 30x more computing power compared with SuperMUC-NG, the current LRZ high-performance computer. It’s called Blue Lion. And it will run on the NVIDIA Vera Rubin architecture.
That’s new. Until now, LRZ — part of the Gauss Centre for Supercomputing, Germany’s leading HPC institution — had only said its next system would use “next-generation” NVIDIA accelerators and processors.
We’re confirming it: That next generation is Vera Rubin, NVIDIA’s upcoming platform for AI and accelerated science.If the name sounds familiar, it should. Last month, Lawrence Berkeley National Lab unveiled Doudna, its next flagship system that will also be powered by Vera Rubin.
Two continents. Two systems. Same architecture.
Together, they form a platform built to collapse simulation, data and AI into a single, high-bandwidth, low-latency engine for science. It combines shared memory, coherent compute and in-network acceleration — and is launching in the second half of 2026.
Blue Lion is built to meet it.
About the System
HPE is building Blue Lion. It will use next-generation HPE Cray technology and feature NVIDIA GPUs in a system equipped with powerful storage and interconnect that harnesses HPE’s 100% fanless direct liquid-cooling systems architecture, which uses warm water delivered through pipes to efficiently cool the supercomputer.
It’s built for researchers working on climate, turbulence, physics and machine learning, with workflows that blend classic simulation and modern AI. Jobs can scale across the entire system. Heat from the racks will be reused to warm nearby buildings.
And it’s not just local. Blue Lion will support collaborative research projects across Europe.
