Struct RowParallelLinear 

Source 
pub struct RowParallelLinear {
    pub weight: Parameter,
    pub bias: Option<Parameter>,
    pub rank: usize,
    pub world_size: usize,
    pub barrier: Arc<CollectiveBarrier>,
}
Expand description

Linear layer with weight sharded along rows (K dimension).

Forward: Y_t = X_t @ W_t (partial sum), then Y = AllReduce(Y_t). Backward: grad_X_t = grad_Y @ W_t^T (no collective).
