The paper addresses the problem of deadlock detection in asynchronous distributed systems for system model that covers unspecified receptions and non-FIFO channels. It presents a hierarchy of deadlock models co
4b,c. Furthermore, it is important to highlight the ability of both DM-1c and DM-3c to break the deadlock of viscous intermittency by being able to reproduce the dip structure in the local scaling exponents, as shown in Fig. 5 in the range τ ≈ τη. Fig. 6 shows how DM ...
When threads share state, problems like race conditions and deadlock etc. may occur. It depends on how the threads use and access the shared objects, of course. Separate state means that the different threads in the system do not share any state among them. In case the different threads ...
A computational model provides an abstraction of a distributed system pro- gramming interface. It is thus interesting to look at the current developments in distributed systems research to understand what a computational model for open distributed systems should contain, and whether extensions to the ...

The delay analysis of the real-time communication network, on the other hand, is presented as a way to ensure the real-time performance of the distributed system. Some works, such as Zhang et al. [41] present a model for verification of the real-time constraints of IMA systems. They ...
(Note that a maximal trace is either an infinite trace or a finite trace that leads to a deadlock state.) For every maximal trace , we know that there is a unique execution e starting from such that , where is the transition system modulo strong bisimulation defined in the standard way....

The figure illustrates the hierarchical break down and the temporal relationships between tasks involved in the "Login" functionality (de- picted in the use case of Section 2.1). More precisely, the task model specifies how the user makes use of the system to achieve his/her goal but also ...
