They are in good company, with X, Meta, Microsoft and others not reporting theirs either.

The basis for the ranking was a cumulative tracking of benchmark results that were required as part of commissioning bespoke computers. A contract would be written to buy a computer that could achieve a certain performance in operations per second, and in order to satisfy that the benchmarks were agreed to and codified in the contracts. Government contracts are to a certain extent public information so the goals and clout of successive performance were tracked in this way.

If you don’t need to satisfy a government contract, or don’t need the clout to attract engineers or funding, submitting results draws unwanted attention to what you’re cooking up.

Microsoft has the #4 cluster on the top 500 list. Sure not everyone reports, still seems like a useful list to watch the trends in computing and in particular HPC.

Keep in mind the average hyperscalers cloud is not a particularly good setup for the top500. HPC tends towards more bandwidth, lower latency, and no virtualization.

Folding-at-home reports theirs. 2020: "Folding@home project passes 2.4 ExaFLOPS, more than the top 500 supercomputers combined" https://www.techspot.com/news/84832-foldinghome-project-pass...
