ASPIRE 1
Also known as NSCC ASPIRE 1; Advanced Supercomputer for Petascale Innovation, Research and Enterprise
Operated by National Supercomputing Centre 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
Singapore's first petascale national supercomputer, a 1,288-node Fujitsu system. TOP500 lists PRIMERGY CX2550 M1 LC and CX2570 M1 LC nodes with Xeon E5-2690v3 12C 2.6GHz on InfiniBand EDR, 30,912 cores, Rmax 1.01 PFlop/s, Rpeak 1.286 PFlop/s and 1,159.2 kW; it debuted at rank 94 in June 2016 and last appeared at rank 422 in November 2018. NSCC's own history page describes it as the 1 PFlops machine that came online in 2016 and states it was decommissioned on 31 August 2023; Asian Scientist's December 2016 launch report gives the same 1,288 nodes and 30,912 cores supplied by Fujitsu Asia.

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 |
