ASPIRE 2B (GPU Partition)
Operated by National Supercomputing Centre Singapore at NSCC (Nanyang Technological University) .
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
Launched by Singapore's Ministry of Digital Development and Information at NSCC's NTU site: a Singapore government minister's own speech states it is a hundredfold increase in compute capacity over ASPIRE 1, and that it will later link to the Quantinuum Helios quantum computer, a rare case in this dataset of a stated future quantum-classical integration path rather than a present one.

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 |
|---|---|---|
| top500.org | names system and part | NVIDIA H200 SXM, AMD EPYC 9005 (Turin), HPE Slingshot-11 |
| mddi.gov.sg | names system and part | NVIDIA H200 SXM |
