Operated by University of Chile at University of Chile Beauchef Campus (NLHPC) .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

| Integrator | - Lenovo ThinkSystem servers, deployed in one water-cooled rack by Chilean integrator Emtec | Lenovo | - | Reported | uchile.clnlhpc.cl |

The read
Chile's national academic supercomputer of the National Laboratory for High Performance Computing (NLHPC), run by the University of Chile's Center for Mathematical Modeling and installed in June 2024 in a single water-cooled rack at the Faculty of Physical and Mathematical Sciences in Santiago. The University of Chile's release and NLHPC's own announcement give 7,360 compute cores, 24,320 GB of RAM, 12 AMD Instinct MI210 GPUs and 4 PB of IBM Elastic Storage System 3200 storage shared with the older Guacolda cluster, with AMD processors in Lenovo servers deployed by the Chilean integrator Emtec, at a cost of about CLP 1,150 million (roughly USD 1.4 million); the operator says it quadruples the capacity of the previous Leftraru machine at twice the energy efficiency. The two announcements quote 260 teraflops while Wikipedia's spec table lists 550 TFLOPS theoretical FP64 and 7,104 cores (27 dual-EPYC 9754 nodes plus two GPU nodes), so no FLOPS figure is recorded here; both sources are tied to the operating university, so confidence is reported.

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 |
|---|---|---|
| uchile.cl | names system, part and count | AMD Instinct MI210 · counts: 12 |
