Jade (LLNL)

Also known as LLNL CTS-1 Jade

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.

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

Penguin Computing CTS-1 commodity cluster in LLNL's SCF zone: 1,302 nodes (6 login, 1,296 batch) of two-socket Intel Xeon E5-2695 v4 (36 cores per node, 128 GB), 46,872 cores in total, Cornelis Networks Omni-Path and TOSS 4, with a CPU peak of 1.575 PFLOPS per LLNL, commissioned 2016. LLNL's page says it is in general availability with a 256-node job limit. LLNL's November 2020 TOP500 write-up lists Jade among its CTS-1 clusters on the list. No HPL figures are recorded here. LLNL is the only source for the specifications, 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.

Every source cited on this page was readable, and none of them mentions this system. They are cited at page granularity, normally because no stable deep link could be found. That is a real weakness in this row and it is why the system carries a confidence tier below verified. See how this check works.
