HPC Interconnect & Fabric Tools
Correctness-first planning tools for HPC and datacenter network architects. Topology math straight from the canonical papers — no hand-waving — turned into switch, cable, transceiver, and fiber bills of materials.

HPC Interconnect Cable Planner
Free HPC cluster cable calculator for fat-tree (folded-Clos), Dragonfly, and 2D/3D torus interconnects. Enter endpoints, switch radix, oversubscription, and speed to get exact switch, cable, transceiver, and fiber counts — a full interconnect bill of materials with DAC/AOC/optical mapping and buy links.

AI Training Cluster Sizer
Free AI training cluster calculator. Enter model params + tokens (or raw FLOPs) with the 6ND rule, pick an H100 / H200 / B200 / GB200 / MI300X / MI325X GPU and MFU, and get GPU count, wall-clock training time (both directions), training VRAM with ZeRO, interconnect bandwidth, power/cooling, and cost.
