Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Rust's notion of Semantic Versioning.

[Unreleased]

Added

  • bellman now uses rayon for multithreading when the (default) multicore feature flag is enabled. This means that, when this flag is enabled, the RAYON_NUM_THREADS environment variable controls the number of threads that bellman will use. The default, which has not changed, is to use the same number of threads as logical CPUs.
  • bellman::multicore::Waiter

Changed

  • bellman::multicore has migrated from crossbeam to rayon:
    • bellman::multicore::Worker::compute now returns bellman::multicore::Waiter.
    • bellman::multiexp::multiexp now returns bellman::multicore::Waiter<Result<G, SynthesisError>> instead of Box<dyn Future<Item = G, Error = SynthesisError>>.

Removed

  • bellman::multicore::WorkerFuture (replaced by Waiter).
