The OMII Software – Demonstrations and Comparisons between two different deployments for Client-Server Distributed Systems

This paper describes the key elements of the OMII software and the scenarios which OMII software can be deployed to achieve distributed computing in the UK e-Science Community, where two different deployments for Client-Server distributed systems are demonstrated. Scenarios and experiments for each deployment have been described, with its advantages and disadvantages compared and analyzed. We conclude that our first deployment is more relevant for system administrators or developers, and the second deployment is more suitable for users’ perspective which they can send and check job status for hundred job submissions

Supporting security-oriented, inter-disciplinary research: crossing the social, clinical and geospatial domains

How many people have had a chronic disease for longer than 5-years in Scotland? How has this impacted upon their choices of employment? Are there any geographical clusters in Scotland where a high-incidence of patients with such long-term illness can be found? How does the life expectancy of such individuals compare with the national averages? Such questions are important to understand the health of nations and the best ways in which health care should be delivered and measured for their impact and success. In tackling such research questions, e-Infrastructures need to provide tailored, secure access to an extensible range of distributed resources including primary and secondary e-Health clinical data; social science data, and geospatial data sets amongst numerous others. In this paper we describe the security models underlying these e-Infrastructures and demonstrate their implementation in supporting secure, federated access to a variety of distributed and heterogeneous data sets exploiting the results of a variety of projects at the National e-Science Centre (NeSC) at the University of Glasgow

How INSPIREd is NERC?

The Natural Environment Research Council (www.nerc.ac.uk) is the UK's main agency for funding and managing research, training and knowledge exchange in the environmental sciences. In 2007 NERC commissioned a consultancy to prepare an INSPIRE baseline and Road Map to enable it to be compliant with the EU INSPIRE Directive well ahead of the deadlines listed in the Directive. This study provided: • A baseline of INSPIRE readiness across NERC with respect to INSPIRE requirements for metadata, discovery, view and download services; • A description of what NERC will need to provide to fully comply with the INSPIRE Directive; • A description of the technology options that are currently envisaged to implement the INSPIRE Directive; • A Road Map to show what NERC must do to meet the INSPIRE Directive; • An estimate of resources required to implement the INSPIRE Directive. This paper outlines the findings of this study

The Open Grid Computing Environments collaboration: portlets and services for science gateways

We review the efforts of the Open Grid Computing Environments collaboration. By adopting a general three-tiered architecture based on common standards for portlets and Grid Web services, we can deliver numerous capabilities to science gateways from our diverse constituent efforts. In this paper, we discuss our support for standards-based Grid portlets using the Velocity development environment. Our Grid portlets are based on abstraction layers provided by the Java CoG kit, which hide the differences of different Grid toolkits. Sophisticated services are decoupled from the portal container using Web service strategies. We describe advance information, semantic data, collaboration, and science application services developed by our consortium.
