Struct LoadTable 

pub struct LoadTable {
    entries: Vec<LoadEntry>,
}

The load table containing entries for all actors.

This lives in mapped memory so both host and GPU can access it.

Fields

entries: Vec<LoadEntry>

Implementations

impl LoadTable

pub fn new(num_actors: usize) -> LoadTable

Create a new load table for num_actors actors.

pub fn get(&self, actor_id: u32) -> Option<&LoadEntry>

Get a reference to an entry.

pub fn get_mut(&mut self, actor_id: u32) -> Option<&mut LoadEntry>

Get a mutable reference to an entry.

pub fn most_loaded(&self) -> Option<(u32, &LoadEntry)>

Find the most loaded actor (best target for work stealing FROM).

pub fn least_loaded(&self) -> Option<(u32, &LoadEntry)>

Find the least loaded actor (best target for work sharing TO).

pub fn imbalance_ratio(&self) -> f64

Compute load imbalance ratio (max_depth / min_depth). Returns 1.0 for perfectly balanced, higher = more imbalanced.

pub fn compute_steal_plan(&self, config: &SchedulerConfig) -> Vec<StealOp>

Compute a work stealing plan: which actors should steal from which.

Returns a list of (thief_id, victim_id, count) tuples. For RoundRobin and Priority strategies, this returns an empty plan since those use a central work queue rather than peer-to-peer stealing.

pub fn entries(&self) -> &[LoadEntry]

Get all entries as a slice.

pub fn len(&self) -> usize

Number of actors in the table.

pub fn is_empty(&self) -> bool

Check if empty.
