From e94f1de0782621e66b71f2cae6ef52c4292108d5 Mon Sep 17 00:00:00 2001 From: Yangwook Kang Date: Sat, 4 Apr 2026 22:03:38 -0700 Subject: [PATCH] Cube-view SVG: detailed topology validation rendering MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Dedicated cube_view renderer showing 6×6 router grid with attachments - PE blocks drawn next to their router (above/below) - HBM pseudo channel port bar (64 ports, color-coded by PE owner) - Per-PE BW annotations on HBM links - Router color-coded by type (PE/M_CPU/SRAM/UCIe/relay) - Title shows mode, channel count, per-PE and total BW - Legend for all component types Co-Authored-By: Claude Opus 4.6 (1M context) --- docs/diagrams/cube_view.svg | 584 ++++++++++++--------------- src/kernbench/topology/visualizer.py | 290 ++++++++++++- tests/test_topology_visualize.py | 5 +- 3 files changed, 548 insertions(+), 331 deletions(-) diff --git a/docs/diagrams/cube_view.svg b/docs/diagrams/cube_view.svg index c3b326a..abc3519 100644 --- a/docs/diagrams/cube_view.svg +++ b/docs/diagrams/cube_view.svg @@ -1,329 +1,259 @@ -
