Expand description

Measured performance of a HigherOrderEngine, from HigherOrderEngine::get_derivative_stats.

Every field is derived from timings recorded by the engine’s own entry points. Before those entry points recorded anything, avg_hvp_time_us, avg_jacobian_time_us and cache_hit_rate were hard-coded zeros.

Fields§

§avg_hessian_time_us: f64

Mean wall time of a full Hessian computation, in microseconds.

§avg_hvp_time_us: f64

Mean wall time of a Hessian-vector product, in microseconds.

§avg_jacobian_time_us: f64

Mean wall time of a Jacobian computation, in microseconds.

§parallel_efficiency: f64

Mean sequential time / mean parallel time over recorded Hessians; 1.0 when only one of the two regimes has been observed.

§sparsity_benefit: f64

Mean dense time / mean sparsified time over recorded Hessians; 1.0 when only one of the two regimes has been observed.

§recorded_computations: usize

Number of timings recorded across all three kinds.

§largest_hessian_problem: usize

Largest problem dimension seen in a recorded Hessian computation.
