Andes (OLCF)
Also known as OLCF Andes
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 | - Two NVIDIA K80 GPUs in each of 9 GPU nodes | NVIDIA | 18 reported | Reported | docs.olcf.ornl.gov |
| CPU | - Two 16-core 3.0 GHz AMD EPYC 7302 per batch node, 704 batch nodes | AMD | 1,408 reported | Reported | docs.olcf.ornl.govolcf.ornl.gov |
| Interconnect | NVIDIA InfiniBand HDR Interconnect Fat tree or dragonfly+ · 200 Gb/s per port · About 0.6 microseconds S8500 Series HDR InfiniBand, 200 Gb/s | NVIDIA | - | Reported | docs.olcf.ornl.gov |
The read
OLCF commodity Linux cluster for pre- and post-processing and analysis of simulation data from Frontier: a 704-node batch partition (two 16-core 3.0 GHz AMD EPYC 7302 and 256 GB per node) plus 9 GPU nodes with two NVIDIA K80 each, on an S8500 series HDR InfiniBand fabric, with water-cooled rear doors. An OLCF news item dated December 11, 2020 describes it as the most powerful commodity cluster the OLCF had deployed and says the K80 nodes came from the earlier Rhea system. The current user guide says the system will be decommissioned at the end of October as users move to the Riker cluster; the year is not stated in the text fetched, so it is still recorded as operational. No FLOPS figures are recorded.

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 |
|---|---|---|
| olcf.ornl.gov | names system and part | NVIDIA InfiniBand HDR |
