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. DGX A100 node counts and local links follow NVIDIA platform documentation; installed memory variant is unverified.

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.
