Implementations§

Source§

impl LoadAggregator

Source

pub fn new(nr_cpus: usize, dcycle_only: bool) -> LoadAggregator

Create a LoadAggregator object that can be given domains and loads by the caller, and then used to create a LoadLedger object.

Source

pub fn calculate(&mut self) -> LoadLedger

Given a LoadAggregator with recorded domain loads, compute the system-wide load, adjusting for infeasible weights when necessary.

Source

pub fn init_domain(&mut self, dom_id: usize)

Init a domain and set default load values. Does nothing if the domain already exists.

Source

pub fn record_dom_load( &mut self, dom_id: usize, weight: usize, dcycle: f64, ) -> Result<()>

Record an instance of some domain’s load (by specifying its weight and dcycle). Returns an error if duty cycle is specified more than once for a given (Domain, weight) tuple.

Source

fn infeasible_threshold(&self) -> f64

Source

fn apply_infeasible_threshold(&mut self, lambda_x: f64)
