Lock-Free Linked List Queue-Based Locks Parking Lot–Based Locks Sequence Lock Teaching Materials Chapter 10. Ideas and Inspiration (虽然自己翻译一遍确实有助于加深理解,但感觉还是过于耗时了。) 本书可以包含无数与并发相关的话题,算法,数据结构,传闻逸
epoch.load(Ordering::Relaxed); atomic::fence(Ordering::SeqCst); // TODO(stjepang): `Local`s are stored in a linked list because linked lists are fairly // easy to implement in a lock-free manner. However, traversal can be slow due to cache // misses and data dependencies. We should...
这个队列使用了一种无锁(lock-free)的算法,来实现在多个线程中高效地并发访问。 具体来说,该文件中包含了以下几个结构体: Slot<T>:这个结构体表示队列中的一个槽,用于存储元素。它有两个字段:value: MaybeUninit<T>表示存储的元素值,next: AtomicPtr<Slot<T>>表示指向下一个槽的指针。AtomicPtr是一个原子...
否则,我们就失去了lock-free应该带来的好处! epoch的工作原理是: A 全局epoch计数器(取值0、1和2) ; A global list of garbage for each epoch;每个opoch都有一个全局垃圾列表; 每个线程的“活动”标志; 每个线程的epoch计数器 epoch用于发现何时垃圾可以安全地释放,因为没有线程可以到达它。与传统的 ...
如果是支持GC的语言编写了上面的代码,那么我们已经实现了一个lock-free stack,但是在rust中不行,因为它发生了内存泄漏.特别是,当Node指针从堆栈中移除后,pop实现不会尝试释放它。 如果我们加上内存释放会有什么问题呢: // extract out the data from the now-unlinked node ...
