Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "We consider the problem of generating a large state-space in a distributed fashion. Unlike previously proposed solutions that partition the set of reachable states according to a hashing function provided by the user, we explore heuristic methods that completely automate the process. The first step is an initial random walk through the state space to initialize a search tree, duplicated in each processor. Then, the reachability graph is built in a distributed way, using the search tree to assign each newly found state to classes assigned to the available processors. Furthermore, we explore two remapping criteria that attempt to balance memory usage or future workload, respectively. We show how the cost of computing the global snapshot required for remapping will scale up for system sizes in the forseeable future. An extensive set of results is presented to support our conclusions that remapping is extremely beneficial."

Download or read book Formal Methods at the Crossroads From Panacea to Foundational Support written by Bernhard K. Aichernig and published by Springer Science & Business Media. This book was released on 2003-11-18 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is devoted to the 10th Anniversary Colloquium of UNU/IIST, the International Institute for Software Technology of the United Nations University, as well as to the memory of Armando Haeberer, who passed away while he was working on the preparation of this book in February 2003. The volume starts with a special paper by Tom Maibaum recollecting Armando Haeberer's life and work. The second part presents work done by members of UNU/IIST as well as a paper on the history of the institute. The subsequent topical sections present key contributions by leading researchers and thus assess the state of the art in software engineering and its engineering and scientific principles, from models to software, real-time systems, and verification. All in all, the book is a unique survey of the power and potential of formal methods in software engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, models and methods for the analysis of the functional correctness of reactive systems, and those for the analysis of their performance (and - pendability) aspects, have been studied by di?erent research communities. This has resulted in the development of successful, but distinct and largely unrelated modeling and analysis techniques for both domains. In many modern systems, however, the di?erence between their functional features and their performance properties has become blurred, as relevant functionalities become inextricably linked to performance aspects, e.g. isochronous data transfer for live video tra- mission. During the last decade, this trend has motivated an increased interest in c- bining insights and results from the ?eld of formal methods – traditionally - cused on functionality – with techniques for performance modeling and analysis. Prominent examples of this cross-fertilization are extensions of process algebra and Petri nets that allow for the automatic generation of performance models, the use of formal proof techniques to assess the correctness of randomized - gorithms, and extensions of model checking techniques to analyze performance requirements automatically. We believe that these developments markthe - ginning of a new paradigm for the modeling and analysis of systems in which qualitative and quantitative aspects are studied from an integrated perspective. We are convinced that the further worktowards the realization of this goal will be a growing source of inspiration and progress for both communities.

This book was released on 2016-07-28 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although computer networks are inherently parallel systems, the parallel execution of network simulations on interconnected processors frequently yields only limited benefits. In this thesis, methods are proposed to estimate and understand the parallelization potential of network simulations. Further, mechanisms and architectures for exploiting the massively parallel processing resources of modern graphics cards to accelerate network simulations are proposed and evaluated.

Book excerpt: Abstract: "Structured approaches based on Kronecker operators for the description and solution of the infinitesimal generator of a continuous-time Markov chains [sic] are receiving increasing interest. However, their main advantage, a substantial reduction in the memory requirements during the numerical solution, comes at a price. Methods based on the 'potential state space' allocate a probability vector that might be much larger than actually needed. Methods based on the 'actual state space', instead, have an additional logarithmic overhead. We present an approach that realizes the advantages of both methods with none of their disadvantages, by partitioning the local state spaces of each submodel. We apply our results to a model of software rendezvous, and show how they reduce memory requirements while, at the same time, improving the efficiency of the computation."
