To solve the problem of efficient storing and updating of model parameters in the learning process, the parameter server is concerned as a high-throughput distributed machine learning (ML) architecture with the emergence of big models with billions of parameters. Current parameter servers, such as the Parameter Server and the Petuum, do not address data management and lack high-level data abstraction...
With the prevalence of virtualization technology, virtual machine networks (VMN) have been widely used in host network applications. To provide fault tolerance and non-stop features to network applications and preserve the network consistency among virtual machines (VM), the distributed snapshot technique of virtual machine networks regains the attention of academia. While existing approaches still...
Virtualisation is a prevalent technology in current computing. Virtualisation can reduce hardware costs by server consolidation, implement "green computing" by reducing power consumption and is an underpinning process for cloud computing enabling the creation of a range of virtual networks and virtual supercomputers. This paper presents performance measurements for a cloning system known...
Service oriented computing (SOC) and cloud computing paradigm has emerged as an approach which enables ubiquitous, on-demand network accesses to a shared pool of flexibly reconfigurable computing resources. The increasing trends of electrical consumption within data centres are a growing concern for business owners as they are quickly becoming a large fraction of the total cost of ownership. There...
With powerful features and cross platform character, web service has been applied in the field of information technology widely. To meet dynamic needs of enterprises, it tends to generate new web applications through service compositions. Due to flaw of designed process or incorrect input, to composite service may encounter various faults during execution. Moreover, the faults often continue to accumulate...
Cloud computing has become a popular computing paradigm in which virtualized and scalable resources are consolidated to provide services over Internet. However, the resource capability of a single cloud is generally limited, and some applications often require various cloud centers over Internet to deliver services together. Therefore, a Virtual Organization (VO) will be a promising approach to integrate...
With the increasing prevalence of large scale cloud computing environment, researchers has draw more attention about how to provide software as a service through the internet. In this paper, a novel approach named vSaaS is proposed in iVIC platform, which is the virtual computing environment for HaaS and SaaS applications. The aim of this approach is to provide the software as a service from a cloud...
With the increasing prevalence of large scale cloud computing environments, how to place requested applications into available computing servers regarding to energy consumption has become an essential research problem, but existing application placement approaches are still not effective for live applications with dynamic characters. In this paper, we proposed a novel approach named EnaCloud, which...
As a prevalent paradigm for flexible, scalable and on-demand provisions of computing services, Cloud computing can be an alternative platform for scientific computing. In this paper, we propose an efficient resource management system for on-line virtual clusters provision, aiming to provide immediately-available virtual clusters for academic users. Particularly, we investigated two crucial problems:...
