Data reification in a concurrent rely-guarantee algebra (2405.05546v1)
Published 9 May 2024 in cs.LO and cs.SE
Abstract: Specifications of significant systems can be made short and perspicuous by using abstract data types; data reification can provide a clear, stepwise, development history of programs that use more efficient concrete representations. Data reification (or "refinement") techniques for sequential programs are well established. This paper applies these ideas to concurrency, in particular, an algebraic theory supporting rely-guarantee reasoning about concurrency. A concurrent version of the Galler-Fischer equivalence relation data structure is used as an example.
