提出了一种新的并发系统的形式化理论,该理论不假设任何原子操作。并发程序的执行被建模为具有两种时序关系的操作执行的抽象集合:“优先”和“可以因果影响”。然后定义了一个原始的进程间通信机制。在第二部分中,互斥是准确地表达在这个模型,并使用通信机制的解决方案。
A novel formal theory of concurrent systems that does not assume any atomic operations is introduced. The execution of a concurrent program is modeled as an abstract set of operation executions with two temporal ordering relations: “precedence” and “can causally affect”. A primitive interprocess communication mechanism is then defined. In Part II, the mutual exclusion is expressed precisely in terms of this model, and solutions using the communication mechanism are given.
