PARAM Yuva II
Also known as Yuva II; C-DAC PARAM Yuva-II
Operated by C-DAC at C-DAC (Pashan, Pune) .
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.

The read
C-DAC's hybrid cluster launched on 9 February 2013 at Pune, the first Indian research institution machine to pass 500 TFlop/s peak (524 TFlop/s quoted). Xeon E5-2670 hosts with Intel Xeon Phi 5110P coprocessors on InfiniBand FDR and C-DAC's own PARAMNet-III, with 200 TB of storage. C-DAC quoted 360.8 TFlop/s Linpack at launch; the TOP500 entry (rank 70 in June 2013) records 388.44 TFlop/s.

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 |
|---|---|---|
| top500.org | names system and part | Intel Xeon E5-2670, Mellanox InfiniBand FDR |
