Trait Implementations§

impl TensorParallel for SingleDeviceTP

fn world_size(&self) -> usize

Number of devices (world size)

fn rank(&self) -> usize

This device’s rank (0-indexed)

fn all_reduce_sum(&self, _tensor: &mut Tensor) -> BackendResult<()>

All-reduce sum: sum tensor across all devices in-place

fn all_gather(&self, local: &Tensor, output: &mut Tensor) -> BackendResult<()>

All-gather: gather local tensors from all devices into output output is world_size * local_size

fn scatter(&self, input: &Tensor, output: &mut Tensor) -> BackendResult<()>

Scatter: split input across devices, each gets 1/world_size

fn barrier(&self) -> BackendResult<()>

Barrier: synchronize all devices
