research papers on distributed systems

A distributed system can be described as a particular sequential state machine that is implemented with a network of processors. The ability to totally order the input requests leads immediately to an algorithm to implement an arbitrary state machine by a network of processors, and hence to Cited by: Thanks to the distributed systems we provide our developers, they are some of the most productive in the industry. And we write and publish research papers to share what we have learned, and because peer feedback and interaction helps us build better systems that benefit everybody. IEEE Transactions on Parallel and Distributed Systems (TPDS) is published monthly. It publishes a range of papers, comments on previously published papers, and survey articles that deal with the parallel and distributed systems research areas of current importance to our readers. The articles in.

In order for these networks to function, software must be able to effectively manage In order for these networks to function, software must be able to effectively manage: unreliable dynamic distributed Replication is one of the popular tools to determine the availability degree of resources e.

Since data grids involve limited file storages and high computing costs, replication process is very essential in Since data grids involve limited file storages and high computing costs, replication process is very essential in these networks.

This paper proposes a dynamic replication mechanism in a data grid that uses a weighted priority-based replication scheme, called WPRS. It specifies a value for each existing in a local storage based on three parameters including price, number of access time, and present time. When a resource is not available for a desired job, it is hired from other sites in the network. The proposed mechanism removes the file having the least value to increase the free space of data storage, research papers on distributed systems.

Simulation results show that the proposed replication mechanism surpasses some of the existing replication methods in terms of the number of successful jobs, number of non-successful jobs, and buy price. Cost-efficient parallel processing of irregularly structured problems in cloud computing environments, research papers on distributed systems. In this paper, we deal with optimizing the monetary costs of executing parallel applications in cloud-based environments.

Specifically, we investigate on how scalability characteristics of parallel applications impact the total costs of Specifically, we investigate on how scalability characteristics of parallel applications impact the total costs of computations. We focus on a specific class of irregularly structured problemswhere the scalability typically depends on the input data. Consequently, dynamic optimization methods are required for minimizing the costs of computation.

For quantifying the total monetary costs of individual parallel computations, the paper presents a cost model that considers the costs for the parallel infrastructure employed as well as the costs caused by delayed research papers on distributed systems. We discuss a method for dynamically finding the number of processors for which the total costs based on our cost model are minimal.

Our extensive experimental evaluation gives detailed insights into the performance characteristics of our approach. Open source development and the World Wide Web. The University of La Laguna is made up of sixty departments on three separate sites. There are some 30, people involved in its There are some 30, people involved in its day-to-day organisation, including students, teaching staff and service and administrative personnel.

Much literature is based on game theoretic analysis, which plays a central role in the work of economists, soci-ologists and Much literature is based on game theoretic analysis, which plays a central role in the work of economists, soci-ologists and psychologists. In this work, we present a parallel implementation of an algorithm that simulates the natural convection of fluids in a closed cavity.

The method is based on the Boussinesq approximation; and it is numerically solved using the finite The method is based on the Boussinesq approximation; and it is numerically solved using the finite volume method, based on the Power-Law research papers on distributed systems scheme.

The software was implemented in Fortran. In this paper an analytical model is established to optimize the cost efficiency of broadcast operations while guarantee required RE and delay. To facilitate analysis on cost, a new metric—WCOF Wireless Channel Occupation Frequencyis introduced to measure the average cost per node incurred by a round of broadcast.

For simplicity delay is measured by the least number of broadcasts to achieve required RE. Performance of Counter based and distance based schemes are investigated in detail using the new model. Analytical results show the relation between the cost efficiency and delay of broadcast schemes and configuration of network and broadcast parameters. It is proved that the new model can be used to choose proper broadcast scheme and parameters for optimal performance.

Task-execution scheduling schemes for network measurement and monitoring. The effectiveness of a previously proposed system for embedding watermarks into video frames in real time using software on an ordinary personal computer was evaluated.

The evaluation results with regard to watermark visibility and survivability, resource consumption, and feasibility show that this system is applicable to various practical uses. The Conference looks for significant contributions to all major fields of the Computer Science and Information Technology in theoretical and practical aspects.

The aim of the conference is to provide a platform to the researchers and practitioners from both research papers on distributed systems as well as industry to meet and share cutting-edge development in the field. DeFog: Fog Computing Benchmarks. Fog computing envisions that deploying services of an application across resources in the cloud and those located at the edge of the network may improve the overall performance of the application when compared to running the application Fog computing envisions that deploying research papers on distributed systems of an application across resources in the cloud and those located at the edge of the network may improve the overall performance of the application when compared to running the application on the cloud.

Howeverthere are currently no benchmarks that can directly compare the performance of the application across the cloud-only, edge-only and cloud-edge deployment platform to obtain any insight on performance improvement. This paper proposes DeFog, a first Fog benchmarking suite to: i alleviate the burden of Fog bench-marking by using a standard methodology, and ii facilitate the understanding of the target platform by collecting a catalogue of relevant metrics for a set of benchmarks, research papers on distributed systems.

The current portfolio of DeFog benchmarks comprises six relevant applications conducive to using the edge. Experimental studies are carried out on multiple target platforms to demonstrate the use of DeFog for collecting metrics related to application latencies communication and computationfor understanding the impact of stress and concurrent users on application latencies, research papers on distributed systems, and for understanding the performance of deploying different combination of services of an application across the cloud and edge.

The purpose of this work is to establish some foundational ground for the logics that can be used to reason on distributed systems where asyncronous message passing is the only possible mechanism for communication, e. We define adtl, a logic with modalities for time and locality. We introduce a complete and decidable axiom system, which characterizes the class of structures that reflect the nature of the causal relation when communications are asyncronous.
