TOP500
VerifiedOnline/Digital
The TOP500 project was launched in 1993 to improve and renew the Mannheim supercomputer statistics, which had been in use for seven years.
Our simple TOP500 approach does not define “supercomputer” as such, but we use a benchmark to rank systems and to decide on whether or not they qualify for the TOP500 list. The benchmark we decided on was Linpack, which means that systems are ranked only by their ability to solve a set of linear equations, A x = b, using a dense random matrix A. Therefore, any supercomputer – no matter what its architecture is – can make it into the TOP500 list, as long as it is able to solve a set of linear equations using floating point arithmetic. We have been criticized for this choice from the very beginning, but now, after 20 years, we can say that it was exactly this choice that has made TOP500 so successful – Linpack therefore was a good choice. And there was, and still is, no alternative to Linpack. Any other benchmark would have been similarly specific, but would not have been so easily available for all systems – a very important factor, as compiling the TOP500 lists twice a year is a very complex process.

HAMBURG, Germany — June 23, 2026 — The 67th edition of the TOP500 list of the world’s most powerful supercomputers was announced today at the ISC 2026 conference in Hamburg, Germany. LineShine, a previously unlisted system installed in China, debuts at No. 1, displacing El Capitan as the world’s most powerful supercomputer as measured by the High Performance Linpack (HPL) benchmark.
El Capitan Retains #1 as JUPITER Becomes Europe’s First Exascale System in the 66th TOP500 List
The 66th edition of the TOP500 list of the world’s most powerful supercomputers was announced today at the SC25 Conference in St Louis, Missouri. The new list reflects continued U.S. leadership in high-performance computing (HPC), historic European milestones, and growing global diversity across architectures and energy-efficient design.
El Capitan Retains Top Spot in 65th TOP500 List as Exascale Era Expands
The 65th edition of the TOP500 showed that the El Capitan system retains the No. 1 position. With El Capitan, Frontier, and Aurora, there are now 3 Exascale systems leading the TOP500. All three are installed at Department of Energy (DOE) laboratories in the United States. The El Capitan system at the Lawrence Livermore National Laboratory, California, remains the No. 1 system on the TOP500. The HPE Cray EX255a system was measured with 1.742 EFlop/s on the HPL benchmark.
The Influence of HPC-ers: Setting the Standard for What’s “Cool”
By: Matthew Ziegler, Director Lenovo Neptune® & Sustainability, Lenovo A look back to supercomputing at the turn of the century When I first attended the Supercomputing (SC) conferences back in the early 2000s as an IBMer working in High Performance Computing (HPC), it was obvious this conference was intended for serious computer science researchers and industries singularly focused on pushing the boundaries of computing. Linux was still in its infancy.
El Capitan achieves top spot, Frontier and Aurora follow behind
The 64th edition of the TOP500 reveals that El Capitan has achieved the top spot and is officially the third system to reach exascale computing after Frontier and Aurora. Both systems have since moved down to No. 2 and No. 3 spots, respectively. Additionally, new systems have found their way onto the Top 10. The new El Capitan system at the Lawrence Livermore National Laboratory in California, U.S.A., has debuted as the most powerful system on the list with an HPL score of 1.742 EFlop/s.
The Evolution, Convergence and Cooling of AI & HPC Gear
By: Matthew Ziegler, Director Lenovo Neptune® & Sustainability, Lenovo Years ago, when Artificial Intelligence (AI) began to emerge as a potential technology to be harnessed as a powerful tool to change the way the world works, organizations began to kick the AI tires by exploring it’s potential to enhance their research or business.
A Look Back: Lenovo @ ISC24
Hamburg, Germany was the perfect backdrop for this year’s International Supercomputing Conference (ISC24) with beautiful weather and a bustling event at Congress Center Hamburg. Near the middle of the showroom floor stood Lenovo’s eye-catching booth featuring the recently announced Lenovo ThinkSystem SR780a V3 taking center stage along with demos outlining the booth showcasing how Lenovo is Transforming HPC & AI for All.

Frontier keeps top spot, but Aurora officially becomes the second exascale machine
The 63rd edition of the TOP500 reveals that Frontier has once again claimed the top spot, despite no longer being the only exascale machine on the list. Additionally, a new system has found its way into the Top 10. The Frontier system at Oak Ridge National Laboratory in Tennessee, USA remains the most powerful system on the list with an HPL score of 1.206 EFlop/s.
Lenovo is Transforming HPC & AI for All
Artificial intelligence (AI) has changed the way we navigate and interact with the world around us. With all eyes laser-focused on AI and the impacts of it, IT decision makers are tasked with responsibly determining how AI can help their organizations and businesses. Organizational benefits include enhancing efficiency and productivity, automating repetitive tasks, and solving complex problems faster.
