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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Accelerator | - NVIDIA Fermi 2070/2075, K40, K80 and A100 GPUs (107 GPU and coprocessor units in all) | NVIDIA | - | Reported | clusterhibrido.cinvestav.mx |

The read
CINVESTAV's hybrid CPU/GPU cluster at the Zacatenco unit in Mexico City, in service since 25 January 2012 and part of the LANCAD national grid alongside systems at UNAM and UAM. CINVESTAV's page (last updated February 2022) lists 254 nodes with 6,852 CPU cores (AMD Interlagos 6274, Intel X5675, E5-2650L v3, Xeon Gold 6342), 107 GPU and coprocessor units (Fermi 2070/2075, K40, K80, A100 and 8 Xeon Phi 7120P), QDR and EDR InfiniBand, Lustre storage and 488 TFlop/s theoretical peak. Wikipedia's current entry gives a smaller CPU count (5,996) and mentions later L40S cards. A 2016 Phys.org item quoted 250 TFlop/s for an earlier configuration. It is grown incrementally and has no TOP500 entry that we found. The operator page is the main source, 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 |
|---|---|---|
| clusterhibrido.cinvestav.mx | names system and part | Mellanox InfiniBand QDR |
