Chapter One: Hello the concurrent world of C + +1. What is concurrencyThe simplest and most basic concurrency is the simultaneous movement of two or more independent activities of two or more.For a single processing unit or core, the machine can

Today, most CPUs have multiple cores, in order to maximize the performance of multi-core processor, improve the concurrency of the server, to ensure that the system for multi-threaded support is very necessary. Our previous design is based on single-
