Germany’s supercomputing landscape just got a massive upgrade, and it’s not just about raw power—it’s about redefining what’s possible in science, sustainability, and innovation. Meet Otus, the newest and largest supercomputer at the Paderborn Center for Parallel Computing (PC2), now officially open for business. But here’s where it gets exciting: Otus isn’t just another supercomputer; it’s a powerhouse designed to tackle some of the most complex challenges in scientific research while setting new benchmarks for energy efficiency and environmental responsibility.
Developed by Lenovo in collaboration with pro-com Datensysteme GmbH, Otus boasts an impressive 142,656 processor cores, primarily powered by AMD’s fifth-generation Epyc processors (codenamed ‘Turin’), alongside 108 Nvidia H100 GPUs. This cluster also features a staggering 5PB of storage, managed by IBM Spectrum Scale, and is already making waves in the tech world. And this is the part most people miss: Even before its official launch, Otus secured the fifth spot on the prestigious ‘Green500’ list, recognizing the world’s most energy-efficient computing systems. How? By sourcing 100% renewable electricity and repurposing its exhaust heat to warm buildings at Paderborn University—a brilliant example of sustainable innovation.
Unveiled in February 2024, Otus is the successor to Noctua 2, PC2’s previous supercomputer. While both systems share a similar core count, Otus delivers twice the computing power, according to PC2. What’s more, its capacity can be expanded further with up to 100 FPGAs, future-proofing its capabilities. But here’s where it gets controversial: As supercomputers grow more powerful, questions arise about their environmental impact. Otus challenges this narrative by proving that high-performance computing and sustainability can go hand in hand. Is this the future of supercomputing, or just a niche exception? We’ll let you decide.
Available to researchers across Germany as part of the national HPC center, Otus will address a wide range of applications—from modeling chemical reactions and optimizing shipping routes to advancing machine learning and improving solar cell efficiency. ‘With Otus, we’re not just building infrastructure; we’re enabling groundbreaking research that tackles complex questions in physics, chemistry, and beyond,’ said Professor Christian Plessl, head of PC2. ‘We’re also setting new standards for energy efficiency and sustainability, and initial tests confirm its exceptional performance.’
At the opening ceremony, Paderborn University’s President, Professor Matthias Bauer, emphasized the broader impact of high-performance computing: ‘Supercomputers like Otus allow researchers to analyze vast datasets, simulate impossible experiments, and predict future developments—all in record time. This isn’t just about technology; it’s about solving the pressing challenges of our time.’ Funded equally by the state of North Rhine-Westphalia and Germany’s federal government at a cost of €14 million (approximately $16 million), Otus represents a significant investment in scientific progress.
As Otus undergoes final acceptance testing in the coming weeks, one thing is clear: it’s not just a machine; it’s a catalyst for innovation. But we want to hear from you: Do you think supercomputers like Otus can truly balance power and sustainability? Or is this an unattainable goal? Let us know in the comments—the conversation starts here.
