Abstract
The snapshot problem addresses a collection of important algorithmic issues related to distributed computations, which are used for debugging or recovering distributed programs. Among existing solutions, Chandy and Lamport have proposed a simple distributed algorithm. In this paper, we explore the correct-by-construction process to formalize the snapshot algorithms in distributed system. The formalization process is based on a modeling language Event B, which supports a refinement-based incremental development using RODIN platform. These refinement-based techniques help to derive correct distributed algorithms. Moreover, we demonstrate how other distributed algorithms can be revisited. A consequence is to provide a fully mechanized proof of the resulting distributed algorithms.

Among existing solutions, Chandy and Lamport have proposed a simple distributed algorithm. In this paper, we explore the correct-by-construction process to formalize the snapshot algorithms in distributed system. The formalization process is based on a modeling language Event B, which supports a refinement-based incremental development using RODIN platform. These refinement-based techniques help to derive correct distributed algorithms. Moreover, we demonstrate how other distributed algorithms can be revisited. A consequence is to provide a fully mechanized proof of the resulting distributed algorithms.</div></front></TEI><affiliations><list><country><li>France</li></country><region><li>Grand Est</li><li>Lorraine (région)</li></region><settlement><li>Metz</li><li>Nancy</li></settlement><orgName><li>Université de Lorraine</li></orgName></list><tree><country name="France"><region name="Grand Est"><name sortKey="Andriamiarina, Manamiary Bruno" sort="Andriamiarina, Manamiary Bruno" uniqKey="Andriamiarina M" first="Manamiary Bruno" last="Andriamiarina">Manamiary Bruno Andriamiarina</name></region><name sortKey="Mery, Dominique" sort="Mery, Dominique" uniqKey="Mery D" first="Dominique" last="Méry">Dominique Méry</name><name sortKey="Singh, Neeraj Kumar" sort="Singh, Neeraj Kumar" uniqKey="Singh N" first="Neeraj Kumar" last="Singh">Neeraj Kumar Singh</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
