This repo is abandoned, but I'll wait for about a year (til August 2025) before archiving it so that any interested rayon contributor can ask questions via issues

Viscose: Prototyping locality-aware fork-join task scheduling for rayon

This project was created to answer one question: what would be the costs and benefits of making the task scheduling of rayon NUMA-aware, and how would the associated code look like in practice?

Other questions that come up along the way (most recently "What is the very costly mfence x86 instruction doing in the the generated assembly for crossbeam::deque's hot code path?") will hopefully also be answered. But in my ideal world, this repo will never become a dedicated library on crates.io, rather its ideas will eventually be integrated into other relevant libraries in the Rust ecosystem.
