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.

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
iREMB is the open GPU cluster of the DGIST Supercomputing and Big Data Center for education and research. A Korean news report of 16 November 2016 says it ranked 351st on the November 2016 TOP500 at 470 TFlop/s, up 53 percent from June after a GPU upgrade and optimisation, and was the top South Korean open system for pure education and research; DGIST planned a 10 Gbps KOREN link. TOP500 lists an HPE Cluster Platform DL380 with Xeon E5-2650v3 10C 2.3 GHz, 10G Ethernet and NVIDIA Tesla K40: 10,244 cores at 456th in June 2016, then 14,400 cores at 352nd in November 2016 and 456th in June 2017, with 0.47 PFlop/s Rmax and 0.98 PFlop/s Rpeak (rank figures differ by one from the news report).
