We consider building a grid Operating System in order to relieve users and programmers from the burden of dealing with the highly distributed and volatile resources of computational grids. To tolerate the volatility of the nodes, the system should be self-healing, that is continuously adapt to additions, removals, and failures of nodes. We present the self-healing architecture of the Vigne grid Operating System through three of its services: system membership, application management, and volatile data management. The experimental results obtained show that our approach is feasible.

Cloud computing is a pattern of processing the big data and provides the convenient, on-demand network access to a shared pool of configurable computing resources. Cloud data center's cost is becoming the hot topic in recent years. This paper studies how to minimize the bandwidth cost for uploading deferral big data to a cloud computing platform, based on the MapReduce Framework. We study the deficiency of randomized online algorithm and Dynamic Self-adaption Algorithm, and we propose the improved algorithm to minimize the bandwidth cost based on DSA, and the results demonstrate that the IDSA' performance is better than the ROA and DSA.

grid is an emerging infrastructure which enables effective coordinate access to various distributedcomputing resources in order to serve the needs of collaborative research and work across the world. grid resource management is always a key subject in the gridcomputing. We first analyze the resource management in the gridcomputing environment, then according to the load imbalance question in the ant colony optimization algorithm, propose an improved algorithm that suits to be used in the grid environment.

In grid environment, resources are widely distributed geographically and belong to different heterogeneous administrative domains respectively, involving various accessing and sharing strategies. In such heterogeneous dynamic environment, it's of considerable realistic value to provide perfect resource information service. In this paper, we study the directory-based service mechanism and structural modules of resource information, and analyze the performance of meta-computing directory service and offer an optimizing strategy. We also provide the on-line gathering and delivery of dynamic parameters of network and CPU and perfect and extend the directory-based resource information structure, and develop a computinggrid oriented prototype system of general information service.

Peta-scale supercomputers enable us to tackle very large-scale problems of which results provide useful information to understand physical phenomena or to improve performance of a product design. The large-scale simulation is becoming dawn to earth due to parallelcomputing techniques, however, inherent barriers on the distributedparallel environment are still remains in simulation process, i. e., grid generation, visualization and data analysis. In this paper, the authors would like to clarify the issues to be resolved for productive support environment of the large-scale simulation, and to propose a foundational framework to enhance the utilization of huge computational resources.

This paper deals with a concurrent version of the finite element time domain method. The algorithm works in SPMD mode and is executed in the MPI distributed environment. Its properties are validated with some different multi-computer, loosely coupled platforms. The real value and approximated asymptotic values of the basic metrics of speedup are presented and discussed.

parallel communication plays a critical role in massively parallel systems, especially in distributed memory systems executing parallel programs on shared data. Therefore, integrating an interconnection network in these systems becomes essential to ensure data inter-nodes exchange. Choose the most effective communication structure must meet certain criteria: speed, size and power consumption. Indeed, the communication phase should be as fast as possible to avoid compromising parallelcomputing, using small and low power consumption modules to facilitate the interconnection network extensibility in a scalable system. To meet these criteria and based on a module reuse methodology, we chose to integrate a reconfigurable SCAC-Net interconnection network to communicate data in SCAC Massively parallel SoC. This paper presents the detailed hardware implementation and discusses the performance evaluation of the proposed reconfigurable SCAC-Net network.

Estimating communication cost involved in executing a program on distributed memory machines is important for evaluating the overheads due to repartitioning. We present a scheme which will work with reasonable efficiency for arrays with at most 3 dimensions. Hyperplane Partitioning technique given by [10] is extended to complete programs by estimating the communication cost by the scheme presented in this work.
