New York Blue

Also known as Stony Brook/BNL Blue Gene

Operated by Stony Brook University at Brookhaven National Laboratory (Upton) .

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.

Measured performance

Rmax: 82.16 TFlop/s
Rpeak: 103.22 TFlop/s
Rmax ÷ Rpeak: 79.6%
Cores: 36,864
Power: 403 kW
Per watt: 0.2 GF/W

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

Eighteen-rack IBM Blue Gene/L owned by Stony Brook University and run at Brookhaven National Laboratory through the New York Center for Computational Sciences, funded with $26 million from New York State. BNL's news release unveiling it on 15 June 2007 says it links more than 36,000 processors for about 100 teraflops of peak and ranked fifth on the June 2007 TOP500. TOP500 records 36,864 PowerPC 440 700 MHz cores, 82.16 TFlop/s Rmax, 103.22 TFlop/s peak and 403 kW, with a presence on the lists through November 2012; the entry used here is tenth on the November 2007 list. TOP500 is the only source for Rmax, so the tier is reported.

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.
