Struct LoopbackExecutor

pub struct LoopbackExecutor;

Description

Single-process protocol oracle for partition, halo, and owned-row action.

Implementations§

§

impl LoopbackExecutor

Signature links:§LoopbackExecutor

pub fn dot( &self, partition: &Partition, left: &[f64], right: &[f64], policy: ReductionPolicy, ) -> Result<f64, Diagnostic>

Signature links:dot Partition f64 f64 ReductionPolicy Result f64 Diagnostic

Compute a distributed dot product from unique-owner contributions.

Each partition accumulates its owned entries in ascending global-index order. The loopback collective then combines partials in partition order. V0 admits only the reproducible policy; Fast requires a native transport collective rather than a misleading loopback implementation.

§Errors

Returns EQ0807 for a policy unsupported by this executor, or EQ0802 for shape/non-finite inputs or reduction overflow.

pub fn apply( &self, operator: &DistributedCsr, input: &[f64], ) -> Result<Vec<f64>, Diagnostic>

Signature links:apply DistributedCsr f64 Result Vec f64 Diagnostic

Apply a distributed CSR plan by splitting owned input, executing the exact halo plan, applying owned rows, and gathering owned output.

§Errors

Returns EQ0802 for shape/non-finite input, a missing halo value, or a non-finite local action.
