Supercomputers to be followed here. Page added April 15, 2025.
Again, these are supercomputers which are different than large data centers (LDCs) which are followed elsewhere.

Updates
October 17, 2025: the EU supercomputer, the Jupiter, sited in Germany, enters the TOP500 list at #4. Link here.
September 11, 2025: El Capitan and Tuolumne update; major update.
July 14, 2025: Mark Zuckerberg / Meta makes huge announcement.
July 8, 2025: over at wiki, no changes since last update, still El Capitan is listed first, as the largest supercomputer.
June 10, 2025: new supercomputer to be built in Germany -- Nvidia and HPE. Link here. Blue Lion. Wasn't IBM known as "big blue"? See this link.
May 30, 2025: Doudna, newest supercomputer announced, DOE, Berkeley. Link here. Also, note Perlmutter at this link. See this link.
May 19, 2025: Taiwan supercomputer, Nvidia, announced. Link here.
May 4, 2025: Colossus 2, announcement. Would be the largest supercomputer in the world (for now). Does one need to start separating "private" supercomputers from "private-public" supercomputers? Right now, unless I learn differently, Colossus 1 and 2 would be considered "private" supercomputers whereas El Capitan and Frontier would be considered "private-public" supercomputers. It's one thing for Hewlett Packard Enterprise to get a government project for "the world's biggest supercomputer." It's quite another thing for one individual -- in this case -- Elon Musk to do it on his own.
From wiki, July 8, 2025: Colossus is a supercomputer developed by xAI, an artificial intelligence (AI) company founded by Elon Musk. Construction on Colossus began in 2024 in Memphis, Tennessee, and is continuing to expand today. It is currently believed to be the world's largest AI supercomputer.
Its purpose is to train the company's AI language model, Grok, and also train the social media service X. It also supports operations for Musk's other companies, such as SpaceX.

Original Page
Back on July 13, 2023, we started tracking supercomputers. Link here. At that time, "Frontier" was the world's largest supercomputer according to wiki.
El Capitan: link here.
Hewlett Packard Enterprise El Capitan is an exascale supercomputer, hosted at the Lawrence Livermore National Laboratory in Livermore, California, United States, that became operational in 2024. It is based on the Cray EX Shasta architecture. El Capitan displaced Frontier as the world's fastest supercomputer in the 64th edition of the TOP500 (Nov. 2024). El Capitan is the third exascale system deployed by the United States and its primary purpose is to support the stockpile stewardship program of the US National Nuclear Security Administration.
The full "top 10" list has three new entrants.
The first non-US supercomputer on the list is #6, a Japanese supercomputer.
I assume classified computers in the DOD and US intel community could be on the top list.
Note the top three on the list above are associated with nuclear energy.
