Fellowships
• Fellow: Marcelo Pasin, from EIA-FR
Subject:The final objective of the proposed fellowship programme is to integrate (to link) the object-oriented distributed programming model of EIA-FR with component based parallel programming environment in order to provide a complete chain of tools starting from the programming language to write the GRID application up to all the necessary services to run the application in a GRID infrastructure. In the period Jun05-Aug05 Marcelo Pasin has been in Fribourg. From Sept.05 he is in Pisa.

Personal perception of the Institute activities
• Evaluation relative to the first year:
Perception (the problems)
• (poorly integrated) Partners
• (small amount of) Short visits / REP
• (few) Joint papers / CoreGRID TR
• Research groups (in)activity
• Participation in the joint activities (emails, call for work ... )
First year review (1)
• D.PM.01 - Roadmap version 1 on Programming Model
• The deliverable presents a concise roadmap concerning the programming model with respect to the state-of-the-art and research strategy and directions. The component-model incorporates Corba, the SOAP protocol and XML for the specification of components. In the near future, a broader state-of-the-art analysis, especially with respect to existing component models, is recommended. Moreover, the interaction with the trust and security area has to be intensified.
Specifically, the Trust and Security survey of WP1 focuses on WS-Security only, but in WP3 also Corba technology is a technological base which is so far not covered in the activities related to Trust and Security. Coverage of non-functional properties, namely timing properties, is also an essential issue for the near future. These aspects might be added in brief form to the deliverable.
Moreover, a clear summary of the technical research results achieved up to now has to be added.
• The model suggested is quite convincing, however what is missing is the relation of this model to the standardisation process going on. Issues such as compatibility, influence on existing standards and leadership in driving the standardisation process should be considered in the next versions of the roadmap.
• The deliverable is accepted
First year review (2)
• WP3: Programming Model
• The component model is the major aspect of this work-package. By providing an umbrella for existing component models, a reasonable and feasible approach has been chosen. The model distinguishes from existing concepts by emphasising aspects such as adaptability and scalability, typically at a relatively coarse-grained component level. The component model should be described more formally, as this is subject of an upcoming deliverable. Within a future evolution of the model, coverage of non-functional properties is a crucial issue and should be addressed intensively.
While the component model itself does not correspond to a concrete implementation, it will be crucial to develop such an implementation within an adjoining project to be acquired by and to distribute it to the other Virtual Institutes for use and evaluation.
• Further evolution of the component model should also be guided by a broader state-of-the-art analysis, taking into account extensions of Enterprise Java Beans, the CORBA Component Model, Microsoft .NET and other related industry and research approaches.
• As already mentioned, a tight integration of the programming model work with trust and security is strongly recommended, for example with respect to specification of security requirements.
• The work-package has clear goals and addresses also important business-related issues like Quality of Service (QoS) and Service Level Agreements (SLA’s).
First year review (3)
• WP3 Programming Models:
• The specification of focussed scenarios comes at the right point in time. The focus on the interaction with other VI’s is necessary, especially with respect to security.
• A stronger involvement in standardisation efforts is in line with the recommendations for this WP.
