Also known as Fuji A*CRC; A*STAR Fujitsu BX900 cluster

Operated by A*STAR Computational Resource Centre .

Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1581 systems have a readable citation that names them, and 64 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

How it compares

Ranked against the other machines in this dataset that report the same figure: those that first came into service within two years of Fuji (A*STAR), and those in Singapore. Computed from our tables; a metric is ranked only when at least eight peers report it.

Rmax32.54 TFlop/s#163 of 177 · bottom 9%#9 of 9 · bottom 1%

Every metric is ranked largest-first, so a high power-draw rank means a big power draw, not a good one. Rmax ÷ Rpeak uses HPL-measured results only. Rankings move as machines are added; they describe this dataset, not the world.

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

Fuji is a Fujitsu PRIMERGY BX900 blade cluster at A*STAR's Computational Resource Centre at Fusionopolis, announced on 22 January 2010 as the first PRIMERGY BX900 supercomputer outside Japan and the most powerful in Southeast Asia. The announcement gives over 35 TFlop/s peak and 91.8 percent LINPACK efficiency, and ties it to a Fujitsu and IHPC petascale applications partnership. TOP500 lists 3,024 cores of Xeon X5570 2.93 GHz on InfiniBand QDR with 32.54 TFlop/s Rmax, 35.44 TFlop/s Rpeak and 175 kW, 261st in June 2010 and 430th in November 2010. A 3,888-core expansion (Xeon X5570/X5670, 41.44 TFlop/s Rmax) was listed separately in June 2011.
