Last time, we left with the question of when you should prefer the strong version of compare-exchange as opposed to the weak version. It comes down to whether spurious failures are acceptable and how expensive they are. In the example given in the presentation, the cost of a spurious failur...
aWe recognize that our study has several limitations. For example, our comparative assessment of strong- and weak- satiation purchase categories focuses on only one example of each. Further research should examine and compare results in additional purchase categories. Our research focuses on six custom...

2.6、compare_exchange_weak函数 2.7、compare_exchange_strong函数 2.8、专业化支持的操作 三、使用示例 总结 一、简介 C++中原子变量(atomic)是一种多线程编程中常用的同步机制,它能够确保对共享变量的操作在执行时不会被其他线程的操作干扰,从而避免竞态条件(race condition)和死锁(deadlock)等问题。 原子变量可以看...

The brokerage metric evaluated the number of connections of a technology that bridge between the otherwise independent technologies, and a high-brokerage technology has a strong bridging capacity that can facilitate knowledge transfer across disciplines [39,40]. The efficiency metric was determined by ...
