eqiora::backends::mpi

Struct OwnedGatherPlanV1 

pub struct OwnedGatherPlanV1 { /* private fields */ }
Description

MPI-v0 count/displacement plan derived from an arbitrary owner map.

Implementations§

§

impl OwnedGatherPlanV1

Signature links:§OwnedGatherPlanV1

pub fn new(partition: &Partition) -> Result<OwnedGatherPlanV1, Diagnostic>

Signature links:newPartitionResultOwnedGatherPlanV1Diagnostic

Derive checked rank-order counts and prefix-sum displacements.

§Errors

Returns EQ0807 when any count, displacement, or total exceeds the signed 32-bit mpi::Count boundary used by mpi 0.8.2.

pub const fn total(&self) -> usize

Signature links:totalusize

Complete receive extent.

pub fn reconstruct( &self, gathered_indices: &[u64], gathered_values: &[f64], ) -> Result<Vec<f64>, Diagnostic>

Signature links:reconstructu64f64ResultVecf64Diagnostic

Reconstruct and validate one complete vector from explicit indices.

Receive blocks are interpreted in rank order using this plan, but global indices are never inferred from counts or displacement.

§Errors

Returns EQ0802 for shape, owner, index, duplicate/missing, or finite- value contradictions.

pub fn reconstruct_into( &self, gathered_indices: &[u64], gathered_values: &[f64], complete: &mut [f64], ) -> Result<(), Diagnostic>

Signature links:reconstruct_intou64f64f64Result()Diagnostic

Validate explicit owner blocks and reconstruct into admitted storage.

§Errors

Returns EQ0802 for shape, owner, index, duplicate/missing, or finite- value contradictions. This method performs no allocation.
