GoogleNetInceptionModule

4 eligible runs
model

KernelBench level3 problem 6: GoogleNetInceptionModule. The computation is the reference PyTorch module's forward pass; the output shape follows the module (mirrored as each implementation's source).

every declared tensor crosses HBM exactly once (3,350 GB/s, H100 SXM datasheet)
no arithmetic formula for this family: bandwidth floor only
headroom-v1: a lower bound from declared tensors and datasheet peaks. A kernel can sit well above it for good reasons.
