摘　　要：程序并行化是充分发挥多核处理器性能的有效手段。现有编程模型受锁、管道等同步方式的约束,并行度很难提高。针对上述问题,提出一种面向多核的基于Rochester软件事务存储(RSTM)系统的冲突管理策略,在现有编程语言中提供接口,通过事务方式提高程序并行度,以优先级方式解决2个事务发生冲突时的裁决问题,减少不必要的一致性验证,减小系统开销。Program parallelization is an available method to exert the multi-core process＇s performance sufficiently.Because the existing programming patterns are limited by synchronization mode,such as lock mechanism and pipeline,the parallelization of them is very difficult to improve.Aiming at the above problem,this paper presents a conflict manager approach based on Rochester Software Transaction Memory（RSTM） system to supply the APIs for the existing program language,which improves the extent of program parallelization by the approach of transaction,and solve the problem of how to arbitrate the conflict of two transactions by the method of PRI.It can cancel some unnecessary consistency validation at some time and reduce the system cost.
