DSM(SVM)is a memory model which was proposed at the 1980s'．DSM provided a possible way to solve the problem that scalability was contradiet with easy pro-gramming．Because DSM was built on the top of message passing scheme．and the cost gap between local reference and remote reference is quite large，the efficiency of DSM will be very low if the authors simply adopt the cache coherence semantic for multiprocessors．So，some Weaken，relaxed coherence semantic model have been proposed,but these mod-els are quite different from sequential Coherence which was assumed by most programmers intuitively，so programming and debugging becomes very difficult．This paper proposes SWHC(strict weak hybrid coherence)model which can eliminate false sharing and provide more temporal and spatial locality,also provides a scheme to keep Seqhential coherent．Experiment results prdved that strict and weak hybrid consistency semantic can eliminate the“thrashing”and improve system performance greatly．
