Memory consistency model
WebC. Simulator Memory Consistency Models The simulator implements two memory consistency models: (1) straightforward sequential consistency and (2) a generic relaxed consistent model. The sequential model is based on three sufficient conditions which, when imple-mented in a multiprocessor, guarantee a sequential consis-tent system.
