Kovan Implements Wait-Free Reclamation For Rust
|
6.7
The author of Lever announces Kovan, a Rust implementation of the Crystalline wait-free memory-reclamation algorithm and an associated wait-free data-structure ecosystem. They report production experience (Lever processed over 25 million operations in under two seconds), M-series Mac benchmarks showing 1.3–1.4× read-heavy performance versus crossbeam-epoch, and TLA+ verification guaranteeing wait-free progress and bounded memory.
Scoring Rationale
Strong practical implementation and TLA+ verification with clear benchmarks; limited scope to Rust/systems and single-author release.
