Hopper NUS
Operated by National University of Singapore .
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
The National University of Singapore's H100 cluster, launched in June 2025 by the NUS IT HPC-AI team on Dell Technologies infrastructure with a high-speed InfiniBand network (NUS also runs the Vanda and Atlas clusters, not in this entry). TOP500 lists a Dell PowerEdge XE9680 system with Xeon Platinum 8480+ CPUs and NVIDIA H100/H200 accelerators on InfiniBand NDR400: 34,592 cores, Rmax 15.05 and Rpeak 24.99 PFlop/s, 105th on its June 2025 debut and 120th in November 2025. NUS quotes 25 PFlop/s and the 105th rank, matching TOP500. It is separate from ASPIRE 2A at NSCC's NUS data centre. No power figure is given, and no machine-room location was found.

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 |
|---|---|---|
| news.nus.edu.sg | names system and part | NVIDIA InfiniBand NDR (Quantum-2) |
| top500.org | names system and part | Intel Xeon Platinum 8480C, NVIDIA InfiniBand NDR (Quantum-2) |
