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.
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.
