PARAM Shakti
Also known as IIT Kharagpur PARAM Shakti
Operated by IIT Kharagpur at IIT Kharagpur Campus .
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
Petascale facility at IIT Kharagpur built by C-DAC under the National Supercomputing Mission. IIT Kharagpur's HPC page describes a heterogeneous hybrid system of Intel Xeon Skylake Gold 6148 and NVIDIA Tesla V100: 384 CPU-only nodes, 36 high-memory nodes with 768 GB and 22 GPU nodes with two V100 each, Mellanox EDR InfiniBand, a Lustre file system of 2.1 PiB primary and 500 TiB archive, CentOS 7.6, and 1.66 PFLOPS peak. The page gives no commissioning date and the system has no TOP500 entry in the editions checked.

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 |
|---|---|---|
| hpc.iitkgp.ac.in | names system, part and count | Intel Xeon Gold 6148, NVIDIA Tesla V100, Mellanox InfiniBand EDR, CentOS · counts: 44 |
