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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Integrator | - HP Cluster Platform 3000 BL460c blades, nearly 1,800 nodes | Hewlett Packard Enterprise | - | Reported | top500.org |
| CPU | - Quad-core Xeon X5365 3 GHz | Intel | - | Reported | top500.org |
The read
Computational Research Laboratories' cluster in Pune, an HP Cluster Platform 3000 BL460c of quad-core 3 GHz Xeon X5365 blades on InfiniBand DDR. Tata's heritage page says the Tata Sons board approved the project in March 2006, it was completed in October 2007, reached 118 teraflops on 31 October and was announced as fourth in the world on 6 November 2007, the first supercomputer built entirely by an Indian company without government funding. TOP500 lists it fourth on the November 2007 list at 117.9 TFLOPS Rmax and 170.88 peak on 14,240 cores. Tata's page notes sustaining commercial business for such a machine became hard but gives no retirement date, so the status date is the data refresh. Node count and cost are not in the pages we cited, and 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.
Every source cited on this page was readable, and none of them mentions this system. They are cited at page granularity, normally because no stable deep link could be found. That is a real weakness in this row and it is why the system carries a confidence tier below verified. See how this check works.
