Webstore-order’ (TSO) memory model. We choose the TSO memory model as the basis of our extension for two reasons:(1)it is a mainstream practical weak memory model (followed by the x86 and SPARC architectures); and(2)it has an intuitive operational semantics in terms of processor-local buffers [Sewell et al. 2010].

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).

WebApr 14, 2024 · The TSO memory model allows strictly more behaviors than the classic SC memory model: writes are first stored in a thread-local buffer and non-deterministically flushed into the shared memory at a later time (also, the write buffers are accessed first when reading a shared variable). WebThe memory model applies to both uniprocessors and shared-memory multiprocessors. Two memory models are supported: total store ordering (TSO) and partial store ordering (PSO). Total Store Ordering (TSO) TSO guarantees that the sequence in which store, FLUSH, and atomic load-store instructions appear in memory for a given processor is identical ...
