SAGA-220
Also known as Supercomputer for Aerospace with GPU Architecture-220 teraflops
Operated by ISRO at Satish Dhawan Supercomputing Facility (VSSC) .
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.

The read
GPU supercomputer built in-house by ISRO's Satish Dhawan Supercomputing Facility at the Vikram Sarabhai Space Centre, inaugurated on 2-3 May 2011 at about Rs 14 crore for launch-vehicle CFD. Both sources give 220 TFlops theoretical peak and about 150 kW, with NVIDIA Tesla C2070 GPUs and quad-core Xeon CPUs; Governance Now counts 400 of each, DQ India counts 436 of each, so no quantity is recorded. DQ India adds Mellanox QDR InfiniBand, 4.5 TB of memory and Xeon E5530 at 2.4 GHz. Current service status is not confirmed by either source, so the status date is the launch date.

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 |
