EC Scientific Gateway Based User Support (SCIBUS) Project
Member of the Advisory Board
[ Project Webpage ]
Short Description:
The SCI-BUS project aims to ease the life of e-Scientists by creating a new science gateway customisation methodology based on the generic-purpose gUSE/WS-PGRADE portal family. The customised science gateways will enable scientists to focus on their work and exploit resources of main Distributed Computing Infrastructures (DCIs) without the need to deal with the underlying infrastructures' details. The project will provide gateway services for various types of user communities and for various NGI user communities. The gateway services will enable unified access to and seamless integration of the underlying networking, computing and data infrastructures and services for all the major DCI infrastructures used in Europe. The SCI-BUS project will provide a portlet repository to the user community and an application repository for the underlying custom applications. This technology will be used by the SCI-BUS project itself to create several customised (or domain-specific) science gateways for different user communities.

2008
International Grid Interoperability and Interoperation Workshop (IGIIW) 2008
Co-located with 4th IEEE International Conference on e-Science
Indianapolis, Indiana, 10th - 12th December 2008
Program Chair and Organizer of IGIIW 2008 Workshop
[ IGIIW 2008 ]
Short Description:
The workshop will discuss the interoperability and interoperation aspects of current Grid and Web technologies, production Grids in general, and the interoperability through emerging open standards and well designed interfaces in particular. In the context of this workshop, the difference between interoperability and interoperation is as follows: Interoperation is specifically defined as what needs to be done to get production Grids (e.g. DEISA, EGEE, TeraGrid) to work together as a fast short-term achievement using as much existing technologies as available today. Hence, this is not the perfect solution and different than interoperability that is defined as the native ability of Grids and Grid middleware (UNICORE, gLite, Globus Toolkit, and others) to interact directly via well defined interfaces and common open standards. This will enable cross-Grid use cases and applications from a growing range of domains in industry and science, taking also recent technologies such as Clouds or Web 2.0 into account.

EC Open Middleware Infrastructure Institute for Europe (OMII-Europe) Project
Member of the OMII-Europe Technical Board
[ Project Webpage ]
Short Description:
The Open Middleware Infrastructure Institute for Europe (OMII-Europe) has been established to provide key software components for building e-Infrastructures within the European Research Area (ERA). The initial focus for OMII-Europe is to facilitate the development and porting of a common set of application level services to a number of major Grid software distributions, and further to develop tighter interoperability between different Grid distributions. This will provide greater application level portability and will thus simplify the use of Grids, especially when those Grids are built on heterogeneous infrastructures. Many of the major Grid software providers such as EGEE, UNICORE, Globus and CROWNGrid are working with OMII-Europe to achieve these goals in a standardscompliant and open-source manner. OMII-Europe will develop and maintain a repository of quality-assured Grid services that have been reengineered and sourced from existing open source repositories. Central to OMII-Europe is Quality Assurance. All OMII-Europe-endorsed software components will undergo rigorous testing following a quality assurance methodology published by OMII-Europe. OMII-Europe positions itself as an impartial broker for potential users of key middleware platforms providing impartial, unbiased advice and services. In line with this, OMII-Europe will initiate development of a Grid benchmarking methodology and publish results on a number of major Grid distributions. This benchmark suite will be made available to the community and OMII-Europe will encourage community benchmark contributions.

This will enable cross-Grid use cases and applications from a growing range of domains in industry and science. The goal of this workshop is to bring together researchers and practitioners working in the area of interoperability and interoperation within Grids and distributed environments, to exchange and share their experiences, new ideas, and latest research results as well as open problems. Enough time for intensive discussions will be provided and outcomes of the workshop will be summarized in the session.
