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 second AI system at the National PARAM Supercomputing Facility in Pune, begun as a 200 AI-petaflops proof-of-concept AI cloud platform under India's National Program on AI. Netweb Technologies built it on AMD EPYC 7742 hosts (81,344 cores total) with NVIDIA A100 GPUs over InfiniBand HDR, running Ubuntu 20.04.2 LTS. C-DAC's own announcement and TOP500 independently agree on the integrator, host CPU, core count, Rpeak and operating system, so the tier is verified; no source states the number or memory configuration of A100 GPUs, so no accelerator quantity is recorded. It debuted 75th on the June 2023 TOP500. C-DAC markets AIRAWAT and PARAM Siddhi-AI together as '410 AI petaflops mixed precision' at the same site, a combined figure this dataset does not reproduce since TOP500 measures each system separately.

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.
