Expand description

Per-worker training result.

Fields§

§device: Device

Device the worker resolved and trained on (the primary lane).

§lanes: Vec<Device>

The backends actually used this run — one for a single device, several for device: "all" (intra-node data-parallel across the node’s hardware).

§inventory: Vec<Device>

Every live backend on this node (what device: "all" could use).

§samples: usize§wall_s: f64§compute_s: f64

Time in backward compute (run()).

§comm_s: f64

Time in the cross-worker gradient reduce (the reduce closure).

§first_loss: f32§last_loss: f32
