Struct CpuBackend 

pub struct CpuBackend { /* private fields */ }

CPU backend backed by a dedicated rayon thread pool.

Implementations

impl CpuBackend

pub fn new() -> Self

Build a backend with a thread pool spanning all logical cores.

pub fn rns_add_single(&self, a: &RnsInt, b: &RnsInt) -> RnsInt

Single-value addition: parallel over channels only when k is large.

Below RAYON_CHANNEL_THRESHOLD channels, rayon’s per-task overhead (~50ns) exceeds the cost of a channel op (~1ns), so we stay sequential.

Trait Implementations

impl ArithmeticBackend for CpuBackend

fn batch_rns_add(&self, a: &RnsBatch, b: &RnsBatch) -> RnsBatch

Elementwise add: result[b][c] = (a[b][c] + b[b][c]) % m[c].

fn batch_rns_mul(&self, a: &RnsBatch, b: &RnsBatch) -> RnsBatch

Elementwise multiply: result[b][c] = (a[b][c] * b[b][c]) % m[c].

fn batch_crt(&self, batch: &RnsBatch) -> Vec<BigUint>

CRT-reconstruct every item in the batch.

fn name(&self) -> &'static str

Backend name for diagnostics.

impl Default for CpuBackend

fn default() -> Self

Returns the “default value” for a type.
