Also known as LLNL CTS-1 Quartz

Operated by Lawrence Livermore National Laboratory at Livermore Computing Center .

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: 2.63 PFlop/s
Rpeak: 3.21 PFlop/s
Rmax ÷ Rpeak: 81.9%

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

Livermore Computing's Quartz, a Penguin Computing Tundra Extreme Scale system of the CTS-1 commodity procurement: nodes of two 18-core Xeon E5-2695 v4 CPUs on Omni-Path, commissioned in 2016 according to LLNL's hardware page, which now marks it decommissioned without a date. TOP500 lists it from 43rd in November 2016 to 71st in November 2018 at 2.63 petaflops Rmax and 3.21 petaflops Rpeak. LLNL counts 3,018 nodes and 108,648 cores while TOP500 counts 95,472 cores, and TOP500's 13,620 kW power figure looks like a facility-level value, so neither cores nor power are recorded. TOP500 is the only source for Rmax and Rpeak, 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.

Cited source	Result	Found on the page
hpc.llnl.gov	names system and part	Intel Xeon E5-2695 v4, Omni-Path Architecture
top500.org	names system and part	Intel Xeon E5-2695 v4, Omni-Path Architecture
