Abstract:

We investigate the formulation of a formal semantics for the industrial software architecture Splice. In this paper, we present a set of basic Splice interaction primitives that is both powerful and easy to implement. We define a semantics for this language based on a conceptual global dataspace. It is shown that the semantics is equivalent to an implementation-biased semantics where each process has its own local dataspace and communication is established by means of asynchronous message passing. Hence, our language allows both convenient reasoning using a global dataspace and efficient implementation by means of distributed dataspaces. The equivalence result is checked mechanically by means of the interactive theorem prover PVS.
