Struct AllToAllRequest

pub struct AllToAllRequest<T: NcclReduceSupported> {
    pub send: GpuRef<T>,
    pub recv: GpuRef<T>,
    pub count: usize,
    pub reply: Sender<Result<(), GpuError>>,
}

Expand description

Symmetric AllToAll: each rank sends an equal-sized shard of length count to every peer. send carries world_size * count elements; recv likewise.

Fields§
