Verifying distributed systems: the operational approach
This work develops an integrated approach to the verification of behaviourally rich programs, founded directly on operational semantics. The power of the approach is demonstrated with a stateof-the-art verification of a core piece of distributed infrastructure, involving networking, a filesystem, and concurrent OCaml code. The formalization is in higher-order logic and proof support is provided by the HOL4 theorem prover. Difficult verification problems demand a wide range of techniques. Here these include ground and symbolic evaluation, local reasoning, separation, invariants, Hoare-style assertional reasoning, rely/guarantee, inductive reasoning about protocol correctness, multiple refinement, and linearizability. While each of these techniques is useful in isolation, they are even more so in combination. The first contribution of this paper is to present the operational approach and describe how existing techniques, including all those mentioned above, may be cleanly and precisely ...
