**Frontier Continues Its Reign as the World's Most Powerful Supercomputer, But Aurora Rises to Challenge**
Frontier has once again claimed the title of the world's most powerful supercomputer, a position it has held since June 2022. However, the competitive landscape is shifting as HPE's Aurora emerges as a formidable contender for the exascale crown. The latest biannual Top500 list highlights the ongoing advancements in supercomputing technology, with Frontier holding firm in the top spot that it has championed for over a year.
**What Sets Frontier Apart?**
Frontier, also known as OLCF-5, boasts an astounding configuration of 8.7 million combined CPU and GPU cores. Until recently, it was the sole exascale supercomputer globally, enabling unprecedented computational capabilities. Frontier has achieved a remarkable performance level, underscoring its role in tackling complex scientific challenges.
**Aurora Joins the Exascale Ranks**
Aurora has officially broken the exascale barrier, showcasing a High-Performance Linpack (HPL) score of 1.012 exaflops per second. To put this in perspective, Aurora can execute calculations in one second that would take the entire population of Earth billions of years to accomplish. Despite only being half-completed in the previous listing, Aurora smoothly ascended to the second position overall in the latest Top500 list, also earning the title of the fastest AI-focused supercomputer.
This system is specifically designed for high-intensive AI workloads, including next-generation AI model training. Notably, when executing AI tasks, Aurora achieves an impressive 10.6 exaflops per second utilizing 89% of its full capacity. In contrast, Frontier's performance on AI workloads is notably lower, at just 2.35 exaflops.
Located at the Argonne Leadership Computing Facility in Illinois, Aurora is constructed on HPE’s Cray EX architecture and leverages Intel’s Max Series GPU technology. Although it was fully installed last August, the system continues to be optimized and is projected to exceed the 2 exaflop barrier, potentially outpacing Frontier.
HPE’s Trish Damkroger highlighted the significance of this breakthrough, stating, “We are honored to celebrate another significant milestone in exascale with Aurora, which delivers massive compute capabilities to make groundbreaking scientific discoveries and address global challenges.” Ogi Brkic from Intel echoed this sentiment, noting the potential of supercomputers like Aurora to help understand critical issues ranging from climate change to the mysteries of the universe.
**The Stability of the Top Tier**
The rankings within the Top500 continue to reflect a great deal of consistency, with Frontier and Aurora holding the top two spots. The third and fourth positions were retained by Eagle and Fugaku, respectively. Microsoft’s Eagle features an impressive 1.12 million computing cores, equipped with Nvidia's H100 chips and Intel’s Xeon Platinum 8480C processors. Launched in August, the AI-centered Eagle supercomputer is designed to enhance access to AI models hosted on Azure.
Fugaku, once the king of supercomputers, now finds itself in fourth place, though it remains the most powerful system outside of the United States. Notably, half of the top ten supercomputers are based in the U.S.
**Introducing New Players**
A new entry into the Top500 is the Alps supercomputer, based at Switzerland’s National Supercomputing Center (CSCS). This HPE Cray system achieved an HPL score of 270 petaflops per second, landing it a cool sixth place and bumping others like Leonardo and Summit down a notch. Despite this, Alps still falls short of challenging LUMI for a top-five finish.
**Dominance of Established Brands in Supercomputing**
The latest Top500 list affirms the dominance of established hardware brands in the supercomputing sphere. Within the top ten, five systems employ Intel Xeon processors, while two leverage AMD processors (Frontier and LUMI) and one uses IBM’s technology (Summit). Fugaku operates on Fujitsu’s custom A64FX microprocessor, an Arm-based CPU, while the newcomer Alps is powered by NVIDIA Grace 72C processors.
**Emergence of New Supercomputers**
Several new supercomputers have made their debut on the Top500, including Baskerville from the University of Birmingham, Yep1 (an Nvidia-driven system operated by Ahrefs), and Dhabi, designed for AI workloads and operated by the Technology Innovation Institute in Abu Dhabi. Additionally, the Isambard-AI supercomputer, the latest and fastest supercomputer in the U.K., has entered the rankings at number 128.
**Recognizing Energy Efficiency in Supercomputing**
Congratulations are also given to JEDI, the newly launched Jupiter supercomputer backed by EuroHPC, for earning the title of the greenest supercomputer globally. This environmentally friendly system is a BullSequana XH3000 with Nvidia’s Grace Hopper superchips, powering 19,584 cores. Remarkably, Isambard-AI secured the second position for energy efficiency, followed by Poland's Cyfronet, emphasizing the increasing focus on sustainability in the realm of high-performance computing. Frontier, while leading overall, was acknowledged for its respectable energy efficiency by ranking 11th in this regard.
With these developments, the world of supercomputing continues to evolve, heralding advancements that will pave the way for groundbreaking discoveries and innovative solutions to complex global challenges.
