If an atomic store in thread A is a release operation, an atomic load in thread B from the same variable is an acquire operation, and the load in thread B reads a value written by the store in thread A, then the store in thread A synchronizes-with the load in thread B. Also, som...

Operation on Queue Basic operations: C++ implementation This article is about queue implementation using array in C++. Queue as an Abstract data Type Queue is an ordered data structure to store datatypes in FIFO (First in First Out) order. That means the element which enters first is first to...
Is there anyway to avoid repetitive class instantiations for all methods in the cpp file? Is there any way in which to simplify the explicit statement of the class when implementing methods in the cpp file that was previously contracted in the h file? Something like... There isn't, but a...
BufferQueue的核心逻辑是生产者消费者逻辑,在BufferQueue这个生产者消费者框架中, BufferQueuecore可以理解为数据缓冲区的管理者,代码逻辑在BufferQueue.cpp和BufferQueuecore.cpp中。 它的原始消费者是BufferQueueConsumer,它的原始生产者是BufferQueueProducer。 那么BufferQueue.cpp 和BufferQueuecore.cpp是什么样的关系呢,可以理...
Similarly a queue who’s pop operation blocks when the queue is empty, and unblocks only when another thread puts an item on the queue. Quote fromhere An example of using such a queue would look like this (notice a fast producer and slow consumer in the code below): ...
65 // inserting in the queue. It might fail if there are more than 1 producer threads because this 66 // operation has to be done in the same order as the previous CAS 67 while(!CAS(&m_maximumReadIndex, currentWriteIndex, (currentWriteIndex + 1))) ...

operation needs to read the head index it's likely that a write operation requires some cache coherency traffic to bring the head index cache line back into exclusive state. In the worst case there will be one cache line transition from shared to exclusive for every read and write operation....
