This publication constitutes the lawsuits of the second one foreign convention on summary country Machines, B and Z, which happened in Orford, quality control, Canada, in February 2010. The 26 complete papers provided have been rigorously reviewed and chosen from 60 submissions. The publication additionally includes invited talks and abstracts of 18 brief papers which tackle paintings in growth, commercial event stories and gear descriptions. The papers hide fresh advances in 4 both rigorous tools for software program and improvement: summary kingdom machines (ASM), Alloy, B and Z. They proportion a standard conceptual framework, established round the notions of nation and operation, and advertise mathematical precision within the modeling, verification and development of hugely responsible platforms.

This would allow for the specialization of concurrency of TUCM for a particular situation or domain. M. Frappier et al. ): ABZ 2010, LNCS 5977, pp. 34–46, 2010. c Springer-Verlag Berlin Heidelberg 2010 AsmL-Based Concurrency Semantic Variations for Timed Use Case Maps 35 – It provides three AsmL-based [5] variations for timed UCM concurrent models: • Interleaving semantics. • True Concurrency semantics. • Run to completion semantics. – It extends the ongoing research towards the construction of a formal framework for the Use Case Maps language [1] to describe, simulate and analyze real-time systems [2,6,3,4].

DeliverMsg is defined as for ReceiveCtl . Synchronous Message Passing and Semaphores: An Equivalence Proof 31 ReceiverStarts: dest has made a ReceiveSema (dest ) move which is followed by a (first) StartSend&WaitSema (m, src, dest ) move that does not Enqueue src into the insema(dest )-queue. SenderStarts implies that, from its StartSend&WaitSema (m, src, dest ) move until reaching the synchronization point, src stayed in the insema(dest )-queue without making any further move. ReceiverStarts implies that between the two moves ReceiveSema (dest ) and StartSend&WaitSema (m, src, dest ), dest has made no move; it will be Dequeued from the outsema(dest )-queue by the subsequent src-move PassMsgSema (src, dest ).

The proof of Theorem 1 is by induction on the number of times a process is scheduled for sending or receiving a message in MsgPassCtl runs. The first two claims of property SndrWait follow from the execution of the first three updates and the SuspendCurr submachine of StartSend&WaitCtl . The waiting phase of a sender is characterized here by the following two properties of the sender: it must be in sndr status—which prevents it from being scheduled because, in order to be scheduled, a process must be in ready status and in (usually at the head of) the scheduler’s readyqueue; be an element of wtsndr of some destination process.
