Operated by IIT Mandi .
Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

The read
Supercomputing facility at IIT Mandi that C-DAC designed and commissioned for IIT Mandi and regional research institutes under the National Supercomputing Mission build approach; the NSM page gives a peak of 838 TFlop/s and names Intel Xeon Cascade Lake processors, NVIDIA Tesla V100 GPUs and HDR100 InfiniBand. The accompanying table lists 107 CPU-only nodes and 39 high-memory (768 GB) nodes with dual Xeon 8268, 10 GPU nodes with two V100 SXM2 cards, 52.416 TB of memory and 1 PiB of parallel storage. No commissioning date appears on the NSM page, so none is recorded, and the table is word for word the same as those of sibling 838 TF machines such as PARAM Ananta (param-ananta). No Linpack result is published.
