Shell Houston HPC Cluster

Also known as Shell Skybox Houston One immersion-cooled AMD EPYC cluster

Operated by Shell at Shell Skybox Houston One Data 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

CPU-only HPC cluster run by Shell IT at the Skybox Houston One data center in Katy, Texas: 864 dual-socket Penguin Solutions Altus servers with 4th Gen AMD EPYC 9654 (96-core) processors, 1,728 CPUs and 165,888 cores, cooled by six GRC ICEraQ Series 10 Duo single-phase immersion units. GRC's customer page puts the installation at 1.2 MW of compute (200 kW per immersion unit), recorded here as power_kw. Shell's Houston data center is stated to run on 100 percent renewable power from Shell Energy North America. No installation date or FLOPS figure is published, so first_operational_date is blank and no Rpeak is recorded; status_as_of is the date of the Penguin Solutions write-up as syndicated by CIO. An AMD case study on the same deployment exists but could not be fetched, so it is not cited. Whether this hall is the same one used by DUG's Bubba at Skybox Houston (also Katy) is not stated by any source, so the site is recorded separately.

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.
