# interleaving semantics (Sect. 3), our novel lock-step semantics (Sect. 4) and a proof-sketch showing that the semantics are equivalent for terminating kernels (Sect. 5). We then discuss the implementation in GPUVerify, and present our experimental results (Sect. 6). We end with related work and conclusions (Sect. 7). 2 A Background Example

The folder 'src' contains the specification of the semantics and all the proofs in Coq: Semantics of Parallelism is the only book which provides a unified treatment of the non-interleaving approach to process semantics (as opposed to the interleaving approach of the process algebraists). Other non-interleaving semantics are investigated and compared. The presentation takes advantage of a parametric definition of process behaviour given in SOS style that permits us to take almost for free the interleaving theory and tools. Finally, we extend our approach to higher-order ß-calculus, enriched with a spawn operation. A stable non-interleaving early operational semantics for the pi-calculus.

a binary relation on graphs containing a pair (G;G ) of graphs if, rst, G is 0 0 an initial graph and G is a terminal graph, second, G can be obtained from G by interleaving direct derivations with the graph transformations speci ed by the used transformation units, and third, the pair is framework and a meta-control model for opportunistically interleaving policy reasoning and web service discovery in enforcing context-sensitive policies (e.g. privacy and security policies). This contrasts with the more scripted approaches to interleaving these two processes adopted in our earlier work on Semantic e-Wallets [7,8].

Reminders should not be used for high-frequency timers- their period should be measured in minutes, hours, or days.

## 2 Semantics and Analysis of Concurrency 2.1 Interleaving and Non-Interleaving models. The semantics community came back to these geometric considerations with 2.2 Higher-Dimensional Automata. Quite a few models for true-concurrency have appeared (see in particular the account of 2.3 Other

interleaving semantics, event structures), quantitative simulation (stochastic semantics), formal languages including bigraphs , Kappa and process algebra. If you look at interleaving model of concurrency, then you can model any concurrent system, and the transition relation is defined with interleaving semantics. Most of the equiv- alence notions currently being considered are based on a semantics where concurrency is modelled by arbitrary interleaving of atomic actions
2.1 Interleaving semantics The execution of processes is said to be concurrent if it is either parallel or interleaved Definition: True-concurrency semantics. With an interleaving semantics, all of i.-iii. are valid outcomes, because we allow interp reters to do computation in any branch.
