Grid middleware infrastructure is a distributed environment suitable for many, typically large-scale, applications. An improved genome sequence alignment algorithm is presented that significantly reduces sequence matching computation time. Yet, very long sequences can still present computation challenges. A small-scale application is implemented on a shared memory system, on a cluster, and the grid-enabled...
Workflow is an important approach for the specification and management of complex processing tasks. This approach is especially powerful for utilizing distributed service and processing resources in grid systems. Some researches on the combination of workflow and grid exist, leading to many approaches to grid workflow support. We describe our MOM-based Service Flow Management System composing complex...
In this paper, we propose a reliability analysis model using the RBD technique to evaluate the reliability of grid environments. In the end the uses of the model are also presented.
DHT routing algorithms have been studied from various aspects. The advantage of this kind of algorithms is that they can locate objects successfully in polylogarithmic overlay hops. Instead of getting testing results via network simulation, this paper describes experiences deploying Emergint, a DHT based peer-to-peer routing algorithm, in a real circumstance aiming to answer the question whether a...
Traditional cache replacement algorithms are not easily applicable to a dynamic and heterogeneous environment. Moreover, the frequently used hit-ratio and byte-hit ratio are not appropriate measures in grid applications, because non-uniformity of the resource object sizes and non-uniformity cost of cache misses in resource information traffic. In this paper, we propose a Least Frequently Cost cache...
This paper presents a novel Grid computing system for drug discovery and design. Utilizing the idle resources donated by the nodes that scatter over the Internet, it can process data-intensive biologic applications. With P2P technologies, the hybrid resource management architecture can avoid some problems, which are inevitable in the traditional master-slave model. Experimental results show the good...
Video-on-demand (VOD) is a service in which a user can view any video program from a server at the time of his choice. In our paper, we present a new effective scheduling scheme, which can intelligently adjust its solution according to available resources and thus achieve an ideal average waiting time. We have realized this protocol in industrial application and have got a good performance.
Many efforts have been made to model small world phenomenon. Kleinberg’s recent research models the construction of small world in a grid and shows the possibility to build an efficient search network with a distributed algorithm. However, it needs to use the global information to form the small world structure, which is unpractical for large-scale and dynamic topologies such as the peer-to-peer systems...
Businesses are entering the next phase of e-Business, in which they need to be able to sense and respond to fluctuating market conditions in real time. IBM is leading the way toward this on-demand world and a number of initiatives are underway to investigate, design and deploy Grid technologies, which form one of the pillars upon which the on-demand environment can be built. Integral part of these...
In this paper, as an attempt to manage Grid resources and schedule Grid applications by a compact and independent system, we propose a framework of Service-based Heterogeneous Distributed Computing (SHDC), which organizes services in the Internet into a P2P network and schedules distributed applications by the cooperation of different peers. In the framework, Grid resources are organized into an addressable...
Data grids provide researching groups with data management services such as Grid-Ftp, Reliable File Transfer Service (RFP), and Replica Location Service (RLS). Especially, Replica Location Service could improve data availability by storing multiple data to the distributed location. In this paper, we propose Tree-based Replica Location Scheme (TRLS) that could support users to decide optimally the...
