Many scientific, engineering and business applications benefit from the ability to submit a large number of computational jobs to a Condor pool simultaneously. However, crafting a correct Condor submission script is not trivial, especially for the less computer command line-savvy users. Therefore, developers often wish to create a job submission page in a Web client application for the Condor system...
To enable the Life Science community to fully use TeraGrid resources for computing and data management, we developed an integrated cyber computational environment named the Open Life Science Gateway. Based on a service-oriented framework, the gateway aggregates a group of bioinformatics applications and data collections into a Web portal. Furthermore, this gateway provides a platform for life science...
Currently in the Internet many collaborative tagging sites exist, but there is the need for a service to integrate the data from the multiple sites to form a large and unified set of collaborative data from which users can have more accurate and richer information than from a single site. In our paper, we have proposed a collective collaborative tagging (CCT) service architecture in which both service...
In this paper we present results on the design and testing of new middleware services for cross-reality data/insight transfer between the real-world and 3D virtual environments. We highlight the architecture that is used along with the implementation of a cyberinfrastructure toolbox containing a set of tools in a virtual environment. The toolbox itself uses a service-oriented architecture to implement...
Virtual organizations are interested in providing secure grid-related services to individual scientist users through portals and invest significant time and effort in managing them. Systems are often in place for users to request and receive grid certificates in many grid infrastructures as a basis for their identity in the grid. These identities are, however, typically disconnected from Web portal...
The design, execution, and monitoring of challenging scientific applications is often a complex affair. To cope with the issue, several tools and frameworks have been designed and put into use. However, the entry barrier to using these tools productively is high, and may hinder the progress of many scientists or non-experts that develop workflows infrequently. As part of the Cyberaide framework, a...
Science portals and gateways are built using a variety of tools ranging from elementary customized tools to existing frameworks that bring both greater capabilities (authentication, account management, interfaces, logging etc) and more complexity (resulting in long learning curves and complex code bases). For gateways, it is important to identify frameworks that can be easily adapted to the specialized...
In this paper, we describe a service oriented architecture and Grid abstraction framework that allows us to access Grids through JavaScript. Obviously, such a framework integrates well with other Web 2.0 technologies. The framework consists of two parts. A client Application Programming Interface (API) to access the Grid via JavaScript and a mediator service and API through which the Grid access is...
Social networking sites have enhanced the Web by providing online "communities" where users can easily create identities, establish relationships between identities, and share resources with one another across the Web. The availability of social networking APIs, such as OpenSocial or the Facebook platform, make it possible for third-party developers to tap into these social relationships...
Progress of research efforts in a novel technology is contingent on having a rigorous organization of its knowledge domain and a comprehensive understanding of all the relevant components of this technology and their relationships. Cloud computing is one contemporary technology in which the research community has recently embarked. Manifesting itself as the descendant of several other computing research...
Cloud computing has become another buzzword after Web 2.0. However, there are dozens of different definitions for cloud computing and there seems to be no consensus on what a cloud is. On the other hand, cloud computing is not a completely new concept; it has intricate connection to the relatively new but thirteen-year established grid computing paradigm, and other relevant technologies such as utility...
The high resolution NEXRAD level II data provides critical information for researchers and the broader community to understand, monitor, and predict weather in a timely manner. There are several limitations in existing systems for providing easy-to-access 3D visualization of the radar data to the user community. In this paper, we present a scalable and user driven solution for near-real-time remote...
The TeraGrid user portal is a Web portal that aggregates and simplifies access to TeraGrid information and services for active TeraGrid users. The vision for the TeraGrid user portal is to become the resource that all TeraGrid users turn to for access, education, use and support of TeraGrid systems. The user portal is an operational activity of the TeraGrid project while also serving as a platform...
