Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

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
The AI Foundry computing infrastructure of the Italian Institute of Artificial Intelligence (AI4I), announced at ISC High Performance 2026 on 23 June 2026 and officially unveiled at OGR Tech in Turin on 16 July 2026. AI4I reports a June 2026 TOP500 result of 4.53 PFlop/s HPL (315th in the 67th edition) and HPCG of 82.6337 TFlop/s (101st), obtained on 148 NVIDIA H200 and B200 GPUs that span two technology generations, one tuned for HPC and one for AI; it does not give the split, the CPUs, power, cooling or the physical site of the machine, so site is blank (Turin is only the unveiling venue). TOP500 (list full for our table, so no list row) lists a mixed HPE ProLiant Compute DL380a Gen12 and Supermicro SuperServer B200 system with Xeon 6710E 64C and Xeon 6960P 72C CPUs, H200 SXM5 141 GB and B200 SXM 180 GB GPUs, InfiniBand NDR400 and Ubuntu 24.04.4, 23,776 cores and 7.61 PFlop/s Rpeak.

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 |
|---|---|---|
| ai4i.it | names system and part | NVIDIA H200 SXM, NVIDIA B200 SXM |
| top500.org | names system and part | NVIDIA H200 SXM, NVIDIA B200 SXM, Intel Xeon 6 6700E (Sierra Forest), Intel Xeon 6 6900P (Granite Rapids), NVIDIA InfiniBand NDR (Quantum-2), Ubuntu Server |
