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
Thailand's national supercomputer, operated by the NSTDA Supercomputer Center (ThaiSC) under the National Science and Technology Development Agency at Thailand Science Park in Pathum Thani. TOP500 and ThaiSC's own operator NSTDA independently agree on the core facts: an HPE Cray EX235n system (NSTDA calls it an HPE Cray EX system) built on AMD EPYC 7713 64-core CPUs and NVIDIA A100 40GB Tensor Core GPUs (NSTDA states 704 of them) over an HPE Slingshot fabric (TOP500 names it Slingshot-11, NSTDA states a 200 Gbps HPE Slingshot network), delivering 8.15 PFlop/s Rmax and 13.77 PFlop/s Rpeak across 87,296 cores and 310.46 kW. NSTDA's own November 2022 announcement states LANTA ranked 70th on that edition's TOP500 list, first in ASEAN, and separately names a 12-petabyte Cray ClusterStor E1000 storage system. Used for Thai-language LLM training (ThaiLLM) and other national AI and HPC workloads, hence workload_class mixed.

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.
