SPR-HBM
Operated by BP .
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.

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
BP's Lenovo ThinkSystem SD650 V3 cluster of Intel Xeon CPU Max 9480 (56-core, 1.9 GHz, on-package HBM) processors on InfiniBand NDR, 119,952 cores at 6.46 PFlop/s Rmax and 7.29 PFlop/s Rpeak on 1,062 kW. It debuted at rank 121 on the November 2023 list, its best placing, and stood at rank 258 on June 2026. TOP500 lists BP's site only as Houston, USA; whether it sits in the Center for High-Performance Computing described by the bp-chpc entry is not stated by any source, so no site is recorded. BP has not published a separate description of the machine.

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.
