Watt a Win: NVIDIA Sweeps New Ranking of World’s Most Energy-Efficient Supercomputers


Recommended Posts

In the latest ranking of the world’s most energy-efficient supercomputers, known as the Green500, NVIDIA-powered systems swept the top three spots, and took seven of the top 10.

The strong showing demonstrates how accelerated computing represents the most energy-efficient method for high-performance computing.

The top three systems were all powered by the NVIDIA GH200 Grace Hopper Superchip, showcasing the widespread adoption and efficiency of NVIDIA’s Grace Hopper architecture.

Leading the pack was the JEDI system, at Germany’s Forschungszentrum Jülich, which achieved an impressive 72.73 GFlops per Watt.

More’s coming. The ability to do more work using less power is driving the construction of more Grace Hopper supercomputers around the world.

Accelerating the Green Revolution in Supercomputing

Such achievements underscore NVIDIA’s pivotal role in advancing the global agenda for sustainable high-performance computing over the past decade.

Accelerated computing has proven to be the cornerstone of energy efficiency, with the majority of systems on the Green500 list — including 40 of the top 50 — now featuring this advanced technology.

Pioneered by NVIDIA, accelerated computing uses GPUs that optimize throughput — getting a lot done at once — to perform complex computations faster than systems based on CPUs alone.

And the Grace Hopper architecture is proving to be a game-changer by enhancing computational speed and dramatically increasing energy efficiency across multiple platforms.

For example, the GH200 chip embedded within the Grace Hopper systems offers over 1,000x more energy efficiency on mixed precision and AI tasks than previous generations.

Redefining Efficiency in Supercomputing

This capability is crucial for accelerating tasks that address complex scientific challenges, speeding up the work of researchers across various disciplines.

NVIDIA’s supercomputing technology excels in traditional benchmarks — and it’s set new standards in energy efficiency.

For instance, the Alps system, at the Swiss National Supercomputing Centre (CSCS), is equipped with NVIDIA Grace Hopper GH200. The CSCS submission optimized for the Green500, dubbed preAlps,It recorded 270 petaflops on the High-Performance Linpack benchmark, used for solving complex linear equations.

The Green500 rankings highlight platforms that provide highly efficient FP64 performance, which is crucial for accurate simulations used in scientific computing. This result underscores NVIDIA’s commitment to powering supercomputers for tasks across a full range of capabilities.

This metric demonstrates substantial system performance, leading to its high ranking on the TOP500 list of the world’s fastest supercomputers. The high position on the Green500 list indicates that this scalable performance does not come at the cost of energy efficiency.

Such performance shows how the Grace Hopper architecture introduces a new era in processing technology, merging tightly coupled CPU and GPU functionalities to enhance not only performance but also significantly improve energy efficiency.

This advancement is supported by the incorporation of an optimized high-efficiency link that moves data between the CPU and GPU.

NVIDIA’s upcoming Blackwell platform is set to build on this by offering the computational power of the Titan supercomputer launched 10 years ago — a $100 million system the size of a tennis court — yet be efficient enough to be powered by a wall socket just like a typical home appliance.

In short, over the past decade, NVIDIA innovations have enhanced the accessibility and sustainability of high-performance computing, making scientific breakthroughs faster, cheaper and greener.

A Future Defined by Sustainable Innovation

As NVIDIA continues to push the boundaries of what’s possible in high-performance computing, it remains committed to enhancing the energy efficiency of global computing infrastructure.

The success of the Grace Hopper supercomputers in the Green500 rankings highlights NVIDIA’s leadership and its commitment to more sustainable global computing.

Explore how NVIDIA’s pioneering role in green computing is advancing scientific research, as well as shaping a more sustainable future worldwide.
