Different scenarios based on environmental changes and water quality models could be used to assess the sustainability and vulnerability of a particular geographical region. The gSWAT and BASHYT platforms provide services and tools supporting the calibration, execution and visualization of the SWAT models. The paper presents the experiments on the execution of different scenarios based on calibrated...
Advanced visualization technologies are gaining major importance to interpret, present and manipulate high dimensional biomedical data. Since new health technologies are constantly increasing in complexity, adequate information processing is required for diagnostics, therapy planning and treatment. The combination of advanced visualization resources and biomedical grid infrastructures is a promising...
Because of the importance effect of visualization in science computation, grid-based visualization has become a new research field, visualization application has visibility and high efficiency, which extends the range of service and the ability of remote access. Based on the campus grid platform, we integrate some multi-subjects parallel software, make a breakthrough on the techniques of web-based...
In this paper we present Real time biomedical data Streaming platform (RIMES), a data-intensive virtual environment, under joint development by Computer Network Information Center and University of California, San Diego. RIMES extends scientists' desktops to biomedical grid computation resources and mass storage systems, by means of streaming biomedical data through internet-based Data Turbine cloud...
This paper presents the design, implementation and testing of the monitoring solution created for integration with a workflow execution platform. The monitoring solution constantly checks the system evolution in order to facilitate performance tuning and improvement. Monitoring is accomplished at application level, by monitoring each job from each workflow and at system level, by aggregating state...
This paper integrates grid technology and OGC compliant services to design and implemented a geospatial Web service platform for the western region's surveying and mapping project. It can make use of OGC common services and interoperability interfaces to supply efficient and secure data management, publishing and inquiries in the heterogeneous computer environment and as well as multi-scale seamless...
This paper presents a framework that extends traditional visualization for supporting distributed visualization in grid environments. This framework adopts the emerging Web services resource framework (WSRF) to deploy visualization algorithms as Web Service on grid nodes. These visualization algorithms are developed by visualization toolkit (VTK) library. Triana, an open source problem solving environment,...

This paper aims at studying the task scheduling in a highly frequent task submitting circumstance in a specific grid environment. The grid is mainly comprised by PCs (personal computers) which in practice will not provide replica information to the grid replica catalogue because the frequent updating operation caused by task execution will consume lots of bandwidth and computing resources. Furthermore...
The graphical modeling and visualization of the virtual geographical space require high power computation and distributed massive spatial databases. The paper presents a few experiments on the solutions supported by the Chromium graphics cluster to provide fast distributed processing and remote visualization. The performance is evaluated for various cluster configurations and spatial data models....
Remote visualization service is an indispensable part for super computing center and network computing services. We present a web-based remote visualization system architecture - ScVisGrid. It provides a web-based interface for end users to access visualization resources in SCCAS by launching visualization tasks in interactive mode. With component-based visualization framework, the existing standalone...
This paper proposes V-STONES: a new circuit provisioning model for future Grid applications. V-STONES differs from existing circuits provisioning model in that it allows end hosts to establish more than one connectivity concurrently with multiple remote systems thus can be used in more complex E-Science application scenarios.
This paper describes our efforts to provide a grid-based parallel visualization environment to visualize massive dataset in parallel. The visualization environment is implemented as a visualization service on the grid. This paper focuses on deploying a proxy process on the master node of each cluster in the grid, to ensure that Globus jobs can be scheduled on internal nodes of clusters that have only...
