fz::LevelTimingResult Struct Reference

#include <perf.h>

Public Attributes
int	level = 0
	Level index (0 = sources)
int	parallelism = 0
	Number of concurrent stages at this level.
float	elapsed_ms = 0.0f
	Critical-path duration: max(stage.elapsed_ms) over the level.

Detailed Description

Aggregate timing for all stages that run concurrently at one DAG level. elapsed_ms is the critical-path duration — the longest stage at the level — because parallel stages overlap on different CUDA streams.
