This paper describes a gridcomputing application for the 3D dynamic analysis of large dimension buildings. A previously developed software composed of parallel implementations of eight direct integration methods has been integrated on this application, in order to perform structural simulations on a grid deployment. The GMarte software abstraction layer has been employed to couple the parallel simulator with the grid infrastructure. Performing distributed executions has enabled a considerable reduction in the global execution time of structural dynamic studies composed of different design alternatives.

This paper discusses a grid-type sensor network with reconfigurable PSoCs as sensor nodes, and details the middleware routines that support the high-level model for distributed programming. The advantages of using reconfigurable PSoCs over other architectures, like MICA2 motes, are also discussed. The paper refers to a case study to illustrate the capabilities of the proposed network concept.

The gridcomputing environment is proposed as a way to enhance the efficiency of the underlying system by maximizing utilization of distributed resources. Dynamic resource allocation algorithms are used to dynamically allocate suitable resources to users' tasks. The efficiency of these algorithms is then vital for both the usability of the grid system and fulfilling its objective. In this paper, we define a formal model of a grid system suitable for a formal analysis of resource allocation algorithms in gridcomputing. We also discuss the use of information which is available to resource allocation algorithm developers, such as researchers and students, who do not have access to an internal grid to compute the efficiency of their algorithms.

Critical to the successful deployment of grid systems is their ability to guarantee efficient meta-scheduling, namely optimal allocation of jobs across a pool of sites with diverse local scheduling policies. The centralized nature of current meta-scheduling solutions is not well suited for the envisioned increasing scale and dynamicity of next-generation grids, the success of which relies on the development of fully distributed, flexible and autonomic systems tailored to very large sets of highly volatile and heterogeneous resources. In this respect, we introduce a fully distributedgrid meta-scheduling scheme that effectively addresses the concerns regarding the scalability and adaptability of future grid systems. Our approach employs a lightweight protocol, called ARiA, that is based on peer-to-peer communication between grid nodes, and makes use of dynamic rescheduling to consider and adapt to changes in the availability of resources. Extensive evaluation by means of an in depth simulation study highlighted the effectiveness of the proposed solution in improving the overall performance in terms of job completion time and load-balancing.

This paper presents the design and implementation of a grid-computing environment for mining sequential patterns. An Apriori-like algorithm for mining sequential patterns is deployed in the proposed grid-computing environment. Apriori-like algorithm is not of very high performance in comparison to others but it is more convenient to be realized for distributed processing in a gridcomputing environment due to its loosely coupled processes. Two types of grids are designed, the computinggrid and data grid, in the proposed environment. All grids are installed with full functions, each of which is wrapped by Globus toolkit. grid services are invoked by the users or other grids and able to respond to the invoking side. There are 10 computers serving as grid nodes each of which is equipped with different hardware components and is distributed on two campuses. The experimental results show that the proposed grid-computing environment provides a flexible and efficient platform for mining sequential patterns from large datasets.

gridcomputing is the collection of computer resources from multiple locations to reach a common goal. According to the task publisher's computing power, we will classify the deceptive detection schemes into two categories, and then analyze the security of deceptive detection schemes based on the characteristics of computational task function. On the basis of double check, we proposed an improved scheme at the cost of time sacrifice called the secondary allocation scheme of double check. In our scheme, the security of double check has been greatly strengthened. Finally, we analyzed the common problem of High-Value Rare Events, improved the deceptive detection scheme due to [1], and then put forward a new deceptive detection scheme with better security and efficiency. This paper is revised and expanded version of a paper entitled "Deceptive Detection and Security Reinforcement in gridcomputing" [2] presented at 2013 5th internationalconference on Intelligent Networking and Collaborative Systems, Xi'an city, Shanxi province, China, September 9-11, 2013.

Computational grids provide significant computing power by sharing resources across administrative domains. But only in secure environment can the performance of girds arrives at maximization. For this purpose we propose a distributed secure structure which emphasis communication of hosts and active security issues in a grid. And then we also discuss the fault tolerance and recovery mechanism for enhancing system reliability.
