The Operations in DeQueue areInitialize –same as circular queue. Insertion at rear – same as circular queue. Deletion from front – same as circular queue. Insertion at from Deletion from rear. Full status check – same a circular queue. Empty status check – same as circular queue...
在使用SSE的时候，前端可以实现流式传输，但是有个问题就是这是一个独占的连接，相当于如果你不手动关闭...
The bandwidth performance, measured using the src/q_bandwidth.cpp shows that this queue is faster by two or three times than boost::lockfree::queue on some of the runs. Implementations Details push(data_type d) operation is composed from the following operations: ...
In addition to agonizing over the design for quite some time, I tested the algorithm using several billion randomized operations in a simple stability test (on x86). This, of course, helps inspire confidence, but proves nothing about the correctness. In order to ensure it was correct, I also...
