WebBoth of these models assume proper synchronization of code and in some cases hardware synchronization support, and so processor consistency is a safer model to adhere to if … Webment the SC memory model. Instead they provide relaxed memory models, which allow subtle behaviors due to hardware and compiler optimizations. For instance, in a multi-processor system implementing the Total Store Order (TSO) memory model [2], each processor is equipped with a FIFO store buffer. In this paper we follow the TSO memory …
Webclassical definition of linearizability is only appropriate for sequentially consistent (SC) memory models, in which accesses to shared memory occur in a global-time linear order. In this paper we suggest an approach for compositional reasoning on a weak memory model of Total Store Order (TSO), implemented by x86 processors [5] (Sections 2, 3).
