A novel method is proposed to monitor and record scientists' working timetable. We record the downloads information of scientific papers real-timely from Springer round the clock, and try to explore scientists' working habits. As our observation demonstrates, many scientists are still engaged in their research after working hours every day. Many of them(More)
The time lower bounds for both uniform consensus and early stopping consensus have already been proved in synchronous distributed systems with crash failures, but both have not been proved with orderly crash failures and remain as open problems. This paper uses a bivalency argument proof to solve the two open problems. The first open problem is how to prove(More)
Most of the existing solutions on task scheduling and resource management in grid computing are based on the traditional client/server model, enforcing a homogenous policy on making decisions and limiting the system flexibility and scalability. In this paper, we propose a peer-to-peer (P2P)-based decentralized approach, which off-loads the intermediate(More)
In our previous study (Wang et al., 2012), we analyzed scientists' working timetable of 3 countries, using realtime downloading data of scientific literatures. In this paper, we make a through analysis about global scientists' working habits. Top 30 countries/territories and Africa are selected as representatives and analyzed in detail. Regional differences(More)
MOTIVATION Grid computing is used to solve large-scale bioinformatics problems with gigabytes database by distributing the computation across multiple platforms. Until now in developing bioinformatics grid applications, it is extremely tedious to design and implement the component algorithms and parallelization techniques for different classes of problems,(More)
Traditional DHT (Distributed Hash Tables) abstraction distributes data items among peer nodes on a structured overlay network. This introduces a number of issues when nodes are under different administrative authorities. In this paper, we propose DGRID, a new DHT abstraction for grid resource indexing and discovery where an administrative domain stores only(More)
This paper discusses a Java-based grid computing middleware, ALiCE, to facilitate the development and deployment of generic grid applications on heterogeneous shared computing resources. The ALiCE layered grid architecture comprises of a core layer that provides the basic services for control and communication within a grid. Programming template in the(More)
Social tagging is an increasingly popular way to describe latent semantic information of web resources and thus is widely used to improve the performance of information retrieval system. However, there also has been significant variance of the quality of social tags because they can be annotated by folks on the web freely. As a consequence, how to measure(More)
