Struct DistributedTrainConfig 

Source 
pub struct DistributedTrainConfig {
    pub world_size: usize,
    pub rank: usize,
    pub local_rank: usize,
    pub role: DistributedRole,
    pub coordinator_addr: SocketAddr,

Expand description

Configuration for distributed pretraining (DDP).

Specifies this worker’s role, rank, and communication topology. All workers must agree on world_size. The coordinator address is where workers connect and where AllReduce is orchestrated.

§Contract

C-DDP-001: After AllReduce + optimizer step, all workers hold identical weights.

Fields§

§world_size: usize

Total number of workers participating

§rank: usize

This worker’s global rank (0-indexed)

§local_rank: usize

This worker’s local rank on its machine (for multi-GPU)

§role: DistributedRole

Role: coordinator (rank 0) or worker

§coordinator_addr: SocketAddr

Address for coordinator to bind / workers to connect

§backend: DistributedBackend

Compute backend for this worker
