In this paper, event order for correct executions in shared-memory systems is systematically investigated with the help of set theory. Starting from a proposed program model which abstracts the memory access characteristics of parallel programs, executions of sequential memory accesses, atomic memory accesses, and nonatomic memory accesses are studied. The necessary and sufficient condition for correct executions in write atomic and write nonatomic systems are presented and proved.
