Struct ParameterServerStats 

pub struct ParameterServerStats {
    pub total_pulls: u64,
    pub total_pushes: u64,
    pub barriers_completed: u64,
    pub max_staleness_observed: u64,
    pub last_grad_norm: f64,
}

Aggregate stats reported by ParameterServer::stats.

Fields

total_pulls: u64

Total pull operations served.

total_pushes: u64

Total push operations applied (sync averages count as one).

barriers_completed: u64

Number of completed sync barriers.

max_staleness_observed: u64

Maximum observed staleness in async mode (pushes since last pull on a shard).

last_grad_norm: f64

Mean squared L2 norm of the most recent applied gradient (per shard).
