Scope and uncertainty

NVIDIA publishes two Eos configurations — 576 DGX H100 systems (4,608 H100 GPUs) and a separate 10,752-GPU Eos DGX SuperPOD used for MLPerf. Which of the two the ranked submission describes is not stated, so no node count is recorded. Node specifications follow the documented DGX H100 platform. Node specifications follow the documented NVIDIA DGX H100 platform (8U rackmount, 6 × 3.3 kW power supplies (4+2 redundant)); operator-specific deviations are not published.

Documented fields: 23 / 29

Every field this catalog checks. Fields listed above have a value; the remainder are shown here. A field marked absent is not publicly available in the sources we could verify, which does not mean the hardware is missing. Fields that cannot apply, such as benchmark results for an unranked system, are excluded from the total.
