c - Lamport 逻辑时钟。它是如何开始工作的？

Question

我知道每个进程都有一个逻辑时钟 C，a->b 如果 C(a) < C(b)。但是他们如何启动这些流程呢？这里我们有一张图片:

他们使用消息传递吗？我们从进程 P1 开始，它向 P2 发送消息？那么P2做什么呢？ P2 在收到 P1 的请求之前做了什么？

Answer 1

P1、P2 和 P3 的工作原理如下:

They all increment independently, but at different frequencies (and aim for synchronization). When an event occurs, the originating process sends its current value to the target process, which checks whether the value received is smaller than its current value. If it is, it changes its current value to received value + 1, else it discards the received value.
