An async-compatible thread-pool aiming for "speed through simplicity".
Forte is a parallel & async work scheduler designed to accommodate very large workloads with many short-lived tasks. It replicates the rayon_core api but with native support for futures and async tasks.
It's design was prompted by the needs of the bevy game engine, but should be applicable to any problem that involves running both synchronous and asynchronous work concurrently.
The thread-pool provided by this crate does not employ work-stealing. Forte instead uses "Heartbeat Scheduling", an alternative load-balancing technique that (theoretically) provides provably small overheads and good utilization. The end effect is that work is only parallelized every so often, allowing more work to be done sequentially on each thread and amortizing the synchronization overhead.
Large portions of the code are direct ports from various versions of rayon_core, with minor simplifications and improvements.
We also relied upon chili and spice for reference while writing the heartbeat scheduling.
Support for futures is based on an approach sketched out by members of the rayon community to whom we are deeply indebted.
