4th EGEE User Forum/OGF 25 and OGF Europe's 2nd International Event

Session

Grid programming

3 Mar 2009, 11:00

Le Ciminiere, Catania, Sicily, Italy

Description

The gLite middleware targets only the foundation and some selected high-level services of the EGEE Grid infrastructure, covering the essential abstractions needed to enable it. On top of the basic gLite interfaces, more advanced solutions can be develop to facilitate the
access to the Grid, both to end users and application developers. These solutions can be higher-level abstractions, sophisticated tools or more intuitive programming environments.

The contributions in the first part of the Grid Programming session present client-side high-level interfaces, in particular addressing the OGF-standard SAGA API. The contributions in the second part present tools and frameworks that facilitate typical Grid operations or provide an alternative job management approach. The session also features a presentation on the security aspects of gLite and how they will evolve in the future.

59. Grid Security: Current Status and Future Development

Emerging Technologies within the EGEE infrastructure

Oral

We give an overview on the current status and future development of the Grid Security infrastructure. In the presentation we will adopt the user's view: how a user interacts with the security components of the grid middleware and explain the advantages and disadvantages of the current PKI-based security. In the outlook we will present current trends in the area of security and how this may...

63. An Extension to the SAGA Service Discovery API

Grid Services exploiting and extending gLite middleware

Oral

The work presented is being undertaken as part of the Simple API for Grid Applications (SAGA) group within the OGF. SAGA aims to provide simple middleware–independent APIs for grid users. This paper outlines the current SAGA Service Discovery API, which provides a means of selecting a set of services based on a number filters; and then goes on to propose an extension that allows access to all...

94. An Approach to Grid Interoperability using Ganga

Grid Services exploiting and extending gLite middleware

Oral

We present our work on Grid interoperability using Ganga. A Gridway backend module was developed to provide access to globus-based grid resources as well. We have also developed an intergrid backend that allows users to submit jobs that have access to both glite-based resources and globus-based resources. In order to demonstrate the usefulness of the new intergrid backend plugin module, we...
