Israel-1
Operated by NVIDIA at NVIDIA Israel (Yokneam) .
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.

|---|---|---|---|---|---|
| Accelerators | 2,048 accelerators | 2023-11 | Design target | Calcalist: 2,048 H100 GPUs at full completion (256 HGX servers); phase one is 1,024 GPUs and 128 servers. | calcalistech.com |
The read
NVIDIA's own commercial AI supercomputer at its Yokneam site, built with Dell on 256 PowerEdge XE9680 servers. Phase 1 (1,024 H100 GPUs) went live in November 2023 under two months ahead of schedule per Calcalistech; the full 2,048-GPU build is what TOP500 benchmarked, 34th on the November 2024 list, its best-ever rank, since overtaken by newer systems through June 2026. NVIDIA is both the vendor of the silicon and the operator of record, an unusual case in this dataset. TOP500 is the only source for Rmax, Rpeak and core count, so the tier is reported.

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 |
|---|---|---|
| calcalistech.com | names system, part and count | NVIDIA H100 SXM5, NVIDIA Spectrum-4 · counts: 2048 |
| top500.org | names system and part | Intel Xeon Platinum 8480C, NVIDIA H100 SXM5, Ubuntu Server |
