并发编程沉思录

In computer science, concurrency refers to the ability of different parts or units of a program, algorithm, or problem to be executed out-of-order or in partial order, without affecting the final outcome. This allows for parallel execution of the concurrent units, which can significantly improve overall speed of the execution in multi-processor and multi-core systems. In more technical terms, concurrency refers to the decomposability property of a program, algorithm, or problem into order-independent or partially-ordered components or units.^[1]

多任务并发，输出一致的结果。

^{1、并发编程是面向task和事务的编程；}

^{2、并发编程的核心是协调资源：计算、内存、io；}

^{3、并发编程模型；}

^{4、并发编程的目标是保证结果的一致性和提高利率；}

^{并发编程世界观：}

^{任务：可分解吗？流水线吗？组装吗？货物拉取型？}

^{资源：任务有基于自愿的相互依赖吗？}

^{任务和资源决定模型；}

^{底层支持：}

^并发控制
