Operated by IISc at IISc Bengaluru .
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
The largest supercomputer at an Indian academic institution at its debut, installed at the Indian Institute of Science (IISc) Bengaluru under the National Supercomputing Mission and designed and integrated by C-DAC on an Atos BullSequana XH2000 platform. Combines Intel Xeon Cascade Lake 8268 CPU nodes (428 standard nodes totalling 20,544 cores and 1.9 PFlop/s, plus 156 high-memory nodes) with an NVIDIA Tesla V100-accelerated GPU partition, for a stated 3.3 PFlop/s peak across the whole machine. IISc's own event page and The Register's independent account agree on the vendor, the CPU/GPU mix and the 3 February 2022 commissioning date, so the tier is verified; no confirmed TOP500 submission has been found despite contemporary press speculating it would eventually appear near rank 160, so ranked is recorded as 0 and only the operator-stated peak figure is given, not an Rmax.

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.
