Scope and uncertainty

766 compute nodes. Eight NDR200 compute-network ports per node; a separate HDR connection serves storage. Local GPU and host wiring remain unverified in this profile.

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.
