Tokio work stealing
Webbwork-stealing从字面理解即工作窃取,工作窃取(work-stealing)算法是指某个线程从其他队列里窃取任务来执行。 工作窃取的运行流程图如下: 那么为什么需要使用工作窃取算法呢? 假如我们需要做一个比较大的任务,我们可以把这个任务分割为若干互不依赖的子任务,为了减少线程间的竞争,于是把这些子任务分别放到不同的队列里,并为每个队列创 …

Webb1 juli 2016 · Tokio is an event-driven, non-blocking I/O platform for writing asynchronous applications with the Rust programming language. At a high level, it provides a few major components: A multithreaded, work-stealing based task scheduler . WebbTake a look at the WorkStealingQueue class which implements the work stealing queue as described in the paper "Dynamic Circular Work-stealing Deque," SPAA, 2015. The structured_task_group class of the PPL uses a work stealing queue for its implementation. If you need a WSQ for threading, I would recommend that.
WebbTokio is fast, gos runtime is also quite fast. The benchmarks mentioned about async rust being slower are from a bad implementation from someone who had never programed much rust before. You can write any program in any language to be slow. It is unlikely that go would be much faster if it is at all. Webb29 juni 2024 · Using multiple thread-pools or even work-stealing threads such as in crossbeam-utils and rayon would be inefficient and would have a lot of OS overhead. This is why I'm thinking of Tokio: it would likely give me a work-stealing thread-pool and would be able to do a lot of concurrent I/O, yielding control back to the pool whenever I/O blocks.
