With increasingly strict data management requirements from funding agencies and institutions, expanding focus on the challenges of research replicability, and growing data sizes and heterogeneity, new data needs are emerging in the materials community. The materials data facility (MDF) operates two cloud-hosted services, data publication and data discovery, with features to promote open data sharing,...
In scientific collaboration platforms such as caGrid, workflow-as-a-service is a useful concept for various reasons, such as easy reuse of workflows, access to remote resources, security concerns, and improved execution performance. We propose a solution for facilitating workflow-as-a-service based on Taverna as the workflow engine and gRAVI as a service wrapping tool. We provide both a generic service...
Web service models are increasingly being used in the Grid community as way to create distributed applications exposing data and/or applications through self describing interfaces. Scientific research is one key field in which the benefits are apparent as individual services can be orchestrated into experimental workflows that model the research process and facilitate verification and extension. However,...
Scientific communities are increasingly exposing information and tools as online services in an effort to abstract complex scientific processes and large data sets. Clients are then able to access services without knowledge of their internal workings therefore simplifying the process of replicating scientific research. Taking a service-oriented approach to science (SOS) facilitates reuse, extension,...
In this paper we present DRIVE, a novel architecture for a virtual organization (VO) based distributed economic meta-scheduler in which members of the VO collaboratively allocate grid resources. Resource providers joining the VO contribute obligation services to the VO. These contributed services are in effect membership 'dues' and are used in the running of the VO's operations - allocation, advertising,...
