From 9a547ee7df958b07937d600978cacc5805cb59b3 Mon Sep 17 00:00:00 2001 From: "russell@unturf.com" Date: Sat, 6 Jun 2026 13:12:36 -0400 Subject: [PATCH] bend.html: cuda-sim-ops-bin gains variant-sweep finding MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extends the cuda-sim-ops-bin row in our form catalog with a measured property: kernel wall scales linearly with Σ Toffoli across circuit variants. foxhop ecdsa lever sweep at p=251 (n+1=9 secp256k1-toy) dispatched 6 lumbda-emitted ops.bin variants through demo_ops on a 3090. Wall vs Toffoli per shot: Fermat-schoolbook 167984 Tof/shot 261.4 ms/batch refined-Solinas 24176 Tof/shot 26.6 ms/batch 9.83x GPU wall reduction matches 6.95x Toffoli ratio + parallel Clifford drop. No scheduler surprise — pick any QECCOPS1 circuit, predict GPU wall from a cheap CPU op-counter.
