Struct MultiDeviceDurations 

pub struct MultiDeviceDurations {
    pub members: Vec<BenchmarkDurations>,
    pub slowest: BenchmarkDurations,
    pub wall: BenchmarkDurations,
}

Every sample of a multi-device benchmark, per member, slowest member and wall.

Fields

members: Vec<BenchmarkDurations>

Member i’s duration in each sample.

slowest: BenchmarkDurations

The slowest member’s duration in each sample: what bounds a step all members take part in.

wall: BenchmarkDurations

The host’s wall around each sample, syncs included.

Implementations

impl MultiDeviceDurations

pub fn new(samples: Vec<MultiDeviceSample>) -> Self

The durations of samples, which all have one member count.

Panics

When samples is empty or their member counts differ.

pub fn median(&self) -> Duration

The median of the slowest member, the figure a step’s cost is read from.

pub fn spread(&self) -> f64

Slowest sample of the slowest member over its fastest: a lower bound on the run’s noise.
