🐙 Poulpy-Backend

Poulpy-Backend is a Rust crate that provides concrete implementations of poulpy-hal. This crate is used to instantiate projects implemented with poulpy-hal, poulpy-core and/or poulpy-schemes.

Backends

cpu-spqlios

This module provides a CPU AVX2 accelerated backend through C bindings over spqlios-arithmetic.

  • Currently supported: FFT64 backend
  • Planned: NTT120 backend

Build Notes

This backend is built and compiled automatically and has been tested on wsl/ubuntu.

  • cmake is invoked automatically by the build script (build.rs) when compiling the crate.
  • No manual setup is required beyond having a standard Rust toolchain.
  • Build options can be changed in /build/cpu_spqlios.rs
  • Automatic build of cpu-spqlios/spqlios-arithmetic can be disabled in build.rs.

Spqlios-arithmetic is windows/mac compatible but building for those platforms is slightly different (see spqlios-arithmetic/wiki/build) and has not been tested in Poulpy.

Example

use poulpy_backend::cpu_spqlios::FFT64;
use poulpy_hal::{api::ModuleNew, layouts::Module};

let log_n: usize = 10;
let module = Module<FFT64> = Module<FFT64>::new(1<<log_n);

Contributors

To add a backend, implement the open extension traits from poulpy-hal/oep for a struct that implements the Backend trait.
This will automatically make your backend compatible with the API of poulpy-hal, poulpy-core and poulpy-schemes.
