kferjaouiandClaude Opus 5.5	e80e552497	perf: add nsys probes for PixelHistogramCUDA ... perf/hist/ mirrors perf/cf/: a driver that runs each config under nsys, the traced process, settings and a README. The fill (H2D + fill_bin_major per frame) and the readout (bin_to_pixel_major + one D2H per values()) are reported separately. Only one chunk of frames is held in host memory and re-queued until the requested frame count. gpu_span.analyze() takes an optional engines subset, so the one-off readout D2H doesn't count towards the fill window or roofline. Default output is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-29 14:25:32 +01:00
kferjaouiandClaude Opus 5.5	b7b786f423	perf: move ClusterFinderCUDA probes into perf/cf/ ... Make room for probes of other CUDA classes. common.py and gpu_span.py stay in perf/ and become shared; the cluster-finder driver, traced process, README and results move to perf/cf/. - common.py: assert_build_fresh() takes the header list, capture_env() takes extra fields, results_dir() takes the probe folder. - cf/cf_common.py: pedestal frames, n_sigma, rebuild-guard headers, DEVICE_PED_TYPE and the <date>_<f32|f64> results naming. - gpu_span.py: optional kernel-name filter; tolerates an engine with no ops. Output without a filter is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-27 12:22:18 +01:00
