WebWe instantiate our framework for the Total Store Ordering (TSO) memory model, and give an algorithm that reduces the fence insertion problem under TSO to the reachability problem for programs running under SC. Furthermore, we provide an abstraction scheme that substantially increases scalability to large numbers of processes. WebMar 24, 2012 · This paper presents the first definition of linearizability on a weak memory model, Total Store Order (TSO), implemented by x86 processors and establishes that the definition is a correct one in the following sense: while proving a property of a client of a concurrent library, it can soundly replace the library by its abstract implementation related …

WebSiFive was founded by the inventors of RISC-V, who have been developing the RISC-V instruction Set Architecture (ISA) since 2010.
