Scope and uncertainty

Partial public profile: processor and fabric follow the TOP500 submission. Node count, socket count, memory and on-node wiring are not assumed from the server model or benchmark core count. This entry describes the ranked system or partition, not every resource operated at this site. Per-node CPU/GPU counts, RAM and local links use NVIDIA DGX H100 platform specifications; operator-specific modifications are not verified.

Not verified means a detail has not been confirmed in this catalog. Diagrams are schematic; node indices are illustrative, not physical hostnames. Data checked 14 September 2026.
