This paper focuses on the energy consumption of content distribution and sharing services that have a significant percentage of traffic on the Internet today. Taking the "energy saving" and "network robustness in traditional traffic engineering" as the dual optimization objects, a weighted green factor is introduced and an optimization model called ETE-FD (Energy-Aware Traffic engineering File Distribution) is established. The model takes into account the overlay layer and the network layer, end systems and routing nodes. A multi-machine parallel algorithm based on dual decomposition and sub-gradient projection is proposed. Even with more than 1000 nodes, the solution process is still fast. Experiments show that the adjustment range of ETE-FD for robustness can reach 58.18%, and the adjustment range of energy consumption can reach 47.09%. In the pure pursuit of performance (robustness) optimization object, the average download time has increased by nearly 90% compared to optimizing only energy consumption object. In the case of pure energy-saving optimization object, the power consumption of ETE-FD is about 10.8% lower than that of EOCFD (Energy-optimal collaborative file distribution). If set to optimize only robustness, it is about 43.9% higher than EOCFD.

The rapid development of the latest distributed computing paradigm, i. e., cloud computing, generates a highly fragmented cloud market composed of numerous cloud providers and offers tremendous parallel computing ability to handle big data problems. One of the biggest challenges in multiclouds is efficient workflow scheduling. Although the workflow scheduling problem has been studied extensively, there are still very few primal works tailored for multicloud environments. Moreover, the existing research works either fail to satisfy the quality of service (QoS) requirements, or do not consider some fundamental features of cloud computing such as heterogeneity and elasticity of computing resources. In this paper, a scheduling algorithm, which is called multiclouds partial critical paths with pretreatment (MCPCPP), for big data workflows in multiclouds is presented. This algorithm incorporates the concept of partial critical paths, and aims to minimize the execution cost of workflow while satisfying the defined deadline constraint. Our approach takes into consideration the essential characteristics of multiclouds such as the charge per time interval, various instance types from different cloud providers, as well as homogeneous intrabandwidth vs. heterogeneous interbandwidth. Various types of workflows are used for evaluation purpose and our experimental results show that the MCPCPP is promising.

Orienting to the competitive exploration of marine resources and the ship intelligent navigation, the broadband and stable maritime communications has regarded as a matter of concern. Due to the particularity of the ocean environment, the maritime communication network is severely restricted compared to the terrestrial one. By understanding the requirement of maritime business, this article deepens the research on maritime communications at offshore areas and ocean and makes a summary of the urgent problems and mainstream communication technologies. Besides, an experimental type of maritime network paradigm based on the coast-5G network involving virtual MIMO technology is present, with a view to providing open issues for the offshore maritime broadband communications.

Joint Meeting of the international symposium on distributed computing and applications to business, engineering and science/international Conference on Parallel Algorithms and computing Evironments

In distributed database systems, replication is the most widely used approach to offering high data availability, increased fault tolerance, and improved scalability of the overall system. However, the primary concern with this technique is not only to provide high availability and reliability but also to boost the performance of data replication, i.e. to minimize response time and maximize throughput. We propose an analytical model for asynchronous replication technique ( ART) by copying the data and replicating it to remote sites on a continuous basis. A remote copy of the data is created at a subsequent time after the primary copy is updated. The model is based on the M/G/1 queuing system by taking into account intersite communication between sites in the systems.

In mobile ad hoc networks (MANETs), a single certificate authority (CA) node could be a security bottleneck. Multiple replica of CA is fault tolerant, but the network is as vulnerable as single CA or even worse since breaking one of the CAs means breaking all of them. Many distributed CA models based on the secret sharing scheme are proposed. In this paper, the suitable construction of the distributed CA is discussed based on the optimization theory. By the analyzing of the characters of the distributed CA in MANETS and the processes of the secure services provided, the optimization model is built. The mean response time of the applications is the optimization goal and the service success probability, system security probability and the loss probability of applications are the constraints in the optimization model. A classic resolving process of the optimization model is given, which is instructional for designing the construction of distributed CA applied in MANETs.

This paper addresses the issue of how to support cloud computing in thin-client/server computing model. We describe the design and implementation of the multple-application-server thin-client/server computing (MAS TC/S) model that allows users with thin-client devices to roam around a wide area network whilst experiencing transparent working environments. MAS TC/S can be applied to a wide variety of applications in wide area network, such as pervasive software rental, service-oriented infrastructure for an Internet service provider, and office automation for transnational corporations. The MAS TC/S architecture model comprises five major components: the display protocol, the multiple-application-server topology, the application-server discovery protocol, the distributed file system, and the network input/output protocol. We discuss problems and present solutions in the design of each constituent component. A prototype of the MAS TC/S that spans the campuses of two universities in Taiwan has been built - we also report our experiences in constructing this prototype. © 2010 IEEE.

The increasingly important data-intensive scientific discovery presents a critical question to the high performance computing (HPC) community-how to efficiently support these growing scientific big data applications with HPC systems that are traditionally designed for big compute applications? The conventional HPC systems are computing-centric and designed for computation-intensive applications. Scientific big data applications have growlingly different characteristics compared to big compute applications. These scientific applications, however, will still largely rely on HPC systems to be solved. In this research, we try to answer this question with a rethinking of HPC system architecture. We study and analyze the potential of a new decoupled HPC system architecture for data-intensive scientific applications. The fundamental idea is to decouple conventional compute nodes and dynamically provision as data processing nodes that focus on data processing capability. We present studies and analyses for such decoupled HPC system architecture. The current results have shown its promising potential. Its data-centric architecture can have an impact in designing and developing future HPC systems for growingly important data-intensive scientific discovery and innovation. © 2016 IEEE.

In computational electromagnetics, parallel computing is more and more studied to deal with large-scale problems which are not able to execute by single PC. Many parallel computing example for electrostatic had been reported. But for electrostatic problems in which floating conductors exist, the realization of parallel is not reported. In the electrostatic model that contains floating conductors, the surfaces of such conductors represent equipotentials but do not constitute a Dirichlet boundary condition. So the partition of such model is difficult to control. This paper presented a way for the partition of the model containing floating conductors and a method that can be used to solve such problem through parallel system. An example which contained three floating conductors was computed by using the method introduced in this paper, the result was displayed and compared with conventional finite element model, the validity of the method is proved. © 2010 IEEE.
