Also known as OLCF Crusher TDS
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Accelerator | AMD Instinct MI250X Accelerators ROCm (CDNA 2) · 1.7 GHz · TSMC N6 · 560 W 4x AMD MI250X per node, 768 in total | AMD | 768 reported | Reported | docs.olcf.ornl.gov |

The read
Moderate-security early-access testbed for Frontier at the OLCF with identical hardware: two cabinets (128 and 64 nodes) holding 192 compute nodes, each with one 64-core AMD EPYC 7A53 and four MI250X (eight GCDs), 768 MI250X GPUs in total, 512 GB DDR4 per node and four HPE Slingshot 200 Gbps NICs per node. Used by CAAR and ECP teams and NCCS staff. The OLCF user guide states it was decommissioned on April 12, 2024. 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.
| Cited source | Result | Found on the page |
