Concurrency control for distributed cooperative engineering applications [PDF]
Distributed cooperative engineering applications require consistent and long-term sharing of large volumes of data, which may cause conflicts due to concurrent read/write operations. Therefore designing concurrency control for underlying middleware systems is a difficult issue.Current transactional solutions, even if based on an optimistic approach, do

A Distributed Concurrency Control Mechanism for XML Data
XML has become a widely used standard for data exchange among applications. Consequently, a large amount of data is distributed on the Web and stored in different persistence models.

Fast Concurrency Control for Distributed Inverted Files [PDF]
A new method for controlling concurrent read/write operations upon inverted files is proposed and evaluated. Communication and synchronization among processors is effected by ways of the bulk-synchronous parallel model of computing. Thanks to the global synchronization property of this model, a simple but very efficient mechanism for synchronizing read/

Study of Concurrency Control Techniques in Distributed DBMS
Concurrency control focuses on maintaining consistency and integrity of database through synchronized access. The complexity relating to concurrency control in a distributed context is very high as compared to centralized framework due to maintaining consistency within the multiple fragments / copies of the database.

Distributed control for systems of concurrent production flow
Abstract A synchronization mechanism for periodic job shops with blocking where concurrent flows of AGVs have to compete safely (i.e. being starvation and deadlockfree) for access to shared system path sectors is investigated. A distributed AGVs control policy that restricts an AGV entering a path sector in an FMS is proposed.

An Extended Three Phase Commit Protocol for Concurrency Control in Distributed Systems
One of the important issues of distributed system is to improve Concurrency control , I observed that Concurrency Control is very difficult task for distributed systems because of absence of global clock and lack of shared memory.

Optimistic Concurrency Control for Distributed Unsupervised Learning
Research on distributed machine learning algorithms has focused primarily on one of two extremes - algorithms that obey strict concurrency constraints or algorithms that obey few or no such constraints. We consider an intermediate alternative in which algorithms optimistically assume that conflicts are unlikely and if conflicts do arise a conflict ...
