“…In its reference implementation, the PROGRESS HPC Portal, the users can utilize computing and data Grid resources with the use of a Web portal (WP). The WP enables end users to access services provided by the Grid Service Provider (GSP) [20,21] and Data Management System (DMS) [22,23] modules. The GSP communicates with the GRB [24] as far as the execution of Grid computing jobs is concerned.…”

SUMMARYIn this paper we present our motivations and ideas for workflow management based on our experiences gained in two projects: GridLab and PROGRESS. In these projects we have been dealing with real use cases and end users' requirements for workflow management. Therefore, we were able to define and implement functional workflow extensions to the Grid(Lab) Resource Management System (GRMS). GRMS is a resource management system with a workflow engine that executes and manages jobs on remote Grid resources. One can submit to GRMS workflow experiments based on an XML workflow schema, defining flexible mechanisms for dynamic workflow control, including various types of precedence constraints, different locations of the final data products and executables, etc. All of these features allow end users to speed up remote workflow calculations and improve data management mechanisms.

“…In this approach, apart from a classical grid management system enabled through a grid resource broker, we introduce the Grid Service Provider which acts as an additional layer between the actual user interfaces, such as portals, and the grid. The Grid Service Provider features high‐level grid services that facilitate the construction of grid portals and access to the computing resources 6, 7. The whole computing environment is assisted by the Data Management System capable of storing large amounts of scientific data 7, 8.…”

SUMMARYThe grid research that has been intensely undertaken in the recent years has resulted in a long list of excellent solutions for the access to and utilization of powerful remote computing resources. Some of these solutions have emerged into standards or good practices widely accepted by the grid community. However, a lot of other important standards are yet to be found and the range of available middleware, protocols and services causes not only a serious problem when deciding on the technology to be used for a particular grid environment, but also poses a major challenge when trying to solve some ongoing issues. The lack of standards and heterogeneity of the grid middleware used is, for example, a big challenge when designing science gateways that are set to provide the scientific community with means of accessing the vast amount of the powerful grid resources delivered by multiple independent grid infrastructures administered by different types of grid management systems. In this paper, we present a method by which we addressed this problem within the PROGRESS project and how it resulted in the design of the grid resource broker plug-in mechanism, which allows the enabling of resources belonging to heterogeneous grid infrastructures within a computing portal.

“…It offers its functionality via GSI-based Web Services that allow to manage the stored files, metadata and file access rights. As far as the data access is concerned, the architecture proposed by the Grid Service Provider within the PROGRESS project has been adopted to enable concurrent access from multiple user applications [13]. The Grid Service Provider introduced a flexible architecture of accessing grid services at high-level of granularity to facilitate construction of grid user interfaces.…”

Over the recent years numerous digital libraries have been deployed and enabled in the Internet with the use of various digital library frameworks. They contain valuable digital resources use of which is important to a large community of users, especially within the scientific and educational communities. The access to distributed digital resources has been a subject of research for a few years now. In this paper we present our own work in this area, discussing our approach at the distributed digital library platform that is widely used within the PIONIER optical network. We present the methodology for building distributed search and access to digital publications that allowed to create a national federation of digital libraries and that is now under investigation for possible use within various application fields including medicine, science and education.
