Struct DistributedVector

pub struct DistributedVector {
    pub local_values: Vec<f64>,
    pub ghost_values: Vec<f64>,
    pub partition: RowPartition,
    pub ghost_rows: Vec<usize>,
}

Expand description

A vector distributed across workers with separate local and ghost storage.

Fields§

§local_values: Vec<f64>

Values for owned rows (length = partition.n_local()).

§ghost_values: Vec<f64>

Values for ghost rows (length = ghost_rows.len()).

§partition: RowPartition

Row ownership metadata.

§ghost_rows: Vec<usize>

Global indices of the ghost rows (parallel to ghost_values).

Implementations§

Source §

impl DistributedVector

Source

pub fn from_global( global: &[f64], partition: &RowPartition, ghost_rows: &[usize], ) -> SparseResult<Self>

Construct a distributed vector by slicing the global vector.

§Arguments

global — The full global vector of length n_global_rows.
partition — Which rows this worker owns.
ghost_rows — Global indices of ghost rows needed by this worker.

Source

pub fn to_global(&self, n_global: usize) -> Vec<f64>

Assemble the full global vector (owned rows only; other entries are 0).

Source

pub fn get_global(&self, global_row: usize) -> Option<f64>

Look up a value by global row index (searches local then ghost storage).
