Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.
What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

The read
Standalone NVIDIA DGX H100 AI/ML system at the Indian Institute of Tropical Meteorology, installed alongside Arka. TOP500 lists NVIDIA DGX H100 with Xeon Platinum 8480C 56C 2GHz and NVIDIA H100 SXM5 80GB on octo-rail NVIDIA HDR100 InfiniBand under Red Hat Enterprise Linux, with 8,176 cores, Rmax 2.70 PFlop/s and Rpeak 3.75 PFlop/s; it first appeared at rank 400 in November 2024 and was 493rd in June 2026. Eviden's release separately describes a dedicated standalone AI/ML system of 1.9 petaflops; the GPU count is not published in the sources fetched, so no quantity is recorded.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
| Cited source | Result | Found on the page |
|---|---|---|
| top500.org | names system and part | Intel Xeon Platinum 8480C, NVIDIA H100 SXM5, NVIDIA InfiniBand HDR |
