…l-to-all due to extent formulation
The EC2 profiling scripts under notebooks/astrasim2_correlation/correlation/ now live in their own repo (rengzhengcodes/aws-gpu-profiler), generalized from an nccl-tests-only orchestrator into a manifest-driven GPU profiler. Wire it in as a submodule at the same path, tracking the profiling-data-20260904 branch, which carries the 2026-09-04 8x H100 all-to-all sweep (run correl-20260904-154601) that the notebook reads. Notebook: read empirical CSVs from correlation/data (inside the submodule) with the repo-root fallback, cite the aws-gpu-profiler run command instead of orchestrate.py, and re-execute in place. Fit unchanged: alpha 74.23 us, BW_eff 339.5 GB/s, R^2 0.9996. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…n git LFS notebooks/astrasim2_correlation/nvlink_probe.ipynb answers the five fabric questions (minimum NVLink packet, NVSwitch capacity, in-network reduction incl. Nsight HBM counters, SM role, launch overhead) from run nvlink-20260917-d of the aws-gpu-profiler nvlink_probe workload, executed inline. The correlation submodule moves to profiling-data-20260904 @ 62170dc, where data/ is stored through git LFS (install git-lfs before 'git submodule update'). correlation.ipynb now selects empirical CSVs by their unified header, so other workloads' results.csv files in the same data tree are ignored.
