Spock

Also known as OLCF Spock

Operated by Oak Ridge National Laboratory at Oak Ridge Leadership Computing Facility .

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

Early-access system for the Frontier programming environment at the OLCF: three cabinets of 12 nodes (36 compute nodes), each with one 64-core AMD EPYC 7662 Rome, 256 GB DDR4, two 3.2 TB NVMe SSDs and four AMD MI100 GPUs (144 GPUs in total), on Slingshot-10 with 12.5 GB/s node injection bandwidth. The OLCF user guide, now an archive, states Spock was decommissioned on March 15, 2023. No FLOPS figures are recorded because none were found in a fetched source.

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.
