Struct TensorParallelConfig 

pub struct TensorParallelConfig { /* private fields */ }

Configuration for tensor parallelism.

Implementations

impl TensorParallelConfig

pub fn new(world_size: usize) -> Result<Self>

Create a TP config with the given number of devices.

Returns Err for world_size == 0 rather than panicking: a zero-rank TP group has no valid shard range, and Fuel’s never-panic rule applies to config construction as much as to a kernel.

pub fn world_size(&self) -> usize

Number of devices in the TP group.

pub fn shard_range( &self, rank: usize, full_size: usize, dim: ShardDim, ) -> (usize, usize)

Compute the [start, end) range for a given rank along a dimension of size full_size.

Ranges are contiguous and cover 0..full_size exactly; the last rank absorbs the remainder when full_size does not divide evenly. When world_size > full_size the leading ranks get empty ranges and the last rank takes everything — degenerate but still a partition, never overlapping.

pub fn make_shard( &self, rank: usize, dim: ShardDim, original_shape: [usize; 2], ) -> TensorShard

Create a TensorShard descriptor.
