Performance metrics for backend selection

Fields

execution_time: Duration

Execution time (measured wall-clock duration of the run)

memory_usage: usize

Memory required for the dense state vector of this circuit, in bytes (2^num_qubits * size_of::<Complex64>()). This is the dominant, exact memory cost of state-vector simulation; it is computed, not measured by a profiler.

cpu_utilization: Option<f64>

CPU utilization during the run. In-process CPU utilization cannot be measured without an external profiler / OS sampling, so this is None unless a caller supplies a measured value.

gpu_utilization: Option<f64>

GPU utilization (if applicable)

throughput: f64

Throughput (gates per second), derived from execution_time

error_rate: Option<f64>

Error rate. None when no error model was applied (no error to report); a measured/estimated rate when available.

Trait Implementations

impl Clone for PerformanceMetrics

fn clone(&self) -> PerformanceMetrics

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PerformanceMetrics

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
