TL;DR: Most C++β―andβ―Rust thread-pool libraries leave significant performance on the table - often running 10Γ slower than OpenMP on classic fork-join workloads and micro-benchmarks. So Iβve drafted a minimal ~300-line library called Fork Union that lands within 20% of OpenMP. It does not use advanced NUMA tricks; it uses only the C++ and Rust standard libraries and has no other dependencies. OpenMP has been the industry workhorse for coarse-grain parallelism in C and C++ for decades. I lean on it heavily in projects like USearch, yet I avoid it in larger systems because:

Wow... https://taskflow.github.io
Taskflow is pretty nice!
The standard parallel algorithms couldn't for_each a big chunk of work, so I gave #taskflow a shot and am really impressed with the simplicity and results.
Ingest time just went from 20 minutes to 5 minutes.
