scirs2_core::random::parallel

Struct DistributedRngPool 

Source 
pub struct DistributedRngPool { /* private fields */ }
Expand description

Workspace-aware parallel RNG for distributed computing

Provides coordination between multiple workers in a distributed system to ensure non-overlapping random sequences.

Implementations§

Source§

impl DistributedRngPool

Source

pub fn new(worker_id: usize, total_workers: usize, base_seed: u64) -> Self

Create a new distributed RNG pool

§Parameters
  • worker_id - Unique identifier for this worker (0-based)
  • total_workers - Total number of workers in the system
  • base_seed - Base seed for the entire distributed system
Source

pub fn get_rng(&self) -> Random<StdRng>

Get a thread-local RNG for this worker

Source

pub fn with_rng<F, R>(&self, f: F) -> R
where F: FnOnce(&mut Random<StdRng>) -> R,

Execute a closure with a worker-local RNG

Source

pub fn worker_info(&self) -> (usize, usize)

Get worker information

Source

pub fn worker_sample<D, T>( &self, distribution: D, total_samples: usize, ) -> Vec<T>
where D: Distribution<T> + Copy,

Generate samples allocated to this worker

Automatically calculates the portion of samples this worker should generate based on its worker ID and the total number of workers.
