• Technical and competent reviewers• Stefano Campadello Nokia research, Finland• Alexander Schill Dresden Univ. of Technology, Germany• Michael Hoevenaars ING, Amsterdam, The Netherlands• Erich Schikuta University of Vienna, Austria• Alfred Geiger T-Systems, Germany

• “Quite interactive” review process

• WP3 presentation (as of slides sent) – Objectives (tasks)– Roadmap (D.PM.01)– Partners (composition, dynamics)– Results (sample)– Integration activities (visits, workshops)– Extra (projects, conferences, etc.)


5

Main observations (WP3)

1. Relationship with “the rest of the world”1. How do you position? Which kind of interaction?

2. Reference/prototype implementation needed1. A: need fundings!

3. Security !!!

4. Industry1. Excellence => fundings and industry interaction2. Industry interaction must be strengthened


6

Main answers

• We are taking into account previous / concurrent experiences – (also as recommended from SAB 05 in Barcelona)

• Security is (to be) one of the research groups– Task force vs. horizontal task even in WP3

• Industry– We should do better

• Reference implementation– Forthcoming (hopefully)– Lightweight specification for openness


7

Review: next JPA

• JPA presented– evolution of JPA1– Continuity + research groups (named themes …)– More focused research topics– Involvement in standardization bodies

• Observations– Standardization bodies participation NEEDED!– More “critic” deliverables, outlining differences with the

existing– Fundamental M30 (all partners using GCM or distinguishing

activities w.r.t. GCM) !!!


8

Personal comments

• Good referee process– Better than expected !

• Nice interaction with referees and officers

• No major comments to wp3 – But the ones we already know!

• Needed a better coordination between partners – Review result of part of us

• Needed more activity on common tasks– Some comments may be avoided …

First year “financial” issues

Most AC partners were unable to justify MM with hired people

too small fundingstoo late hiring

At the moment the underspent money is reported to the second year

Situation *must* be corrected during the second year


13

Meetings

Charleroi meeting first “de visu” meeting of all partners

Jan 2004, Pisa meetingroadmap outlined

Barcelona meeting (Jun 2005)Fractal and research groups

Sophia Antipolis, Oct 2005 meetingfirst “explicit” Task 1.1 sessionD.PM.02 design session

Electronic meetings

Decided in Barcelona

No followup

- collect addresses (chat, Skype, iChat, Messanger, …) on a private WEB page

- exploit existing framework(EIA-FR Switch facilities tested (3 partners))

- spare “explorative” and finalization short visits

Pubblications

• About 20 publications by single partners related to topics of the Programming model Virtual institute

• About 15 joint publications by partners of the Virtual institute

• Startup

– more activity expected while going on

– as effect of achieved integration

JPA2: MM

JPA2: deliverables

Some committments here

- workshop at M30


24

JPA2: milestones


25

JPA2: research groups (1)

• Programming models for the single componentwhich are the more suitable programming models that can be exploited in the implementation of a single component

• Communications (inter and intra component)point to point and collective communication implementation and optimisation

• Primitive component definitionmechanisms and formalisms to be used to define a component

• Hierarchical component compositionall the details related to the definition of new components out of the composition of existing ones

• Advanced programming modelsnew programming models that offer the programmer more advanced tools and higher level mechanisms to implement grid applications on top of the component model


26

JPA2: research groups (2)

• Performance modelsthe possibility to model the behaviour of component execution in such a way unexpected behavior can be discovered by monitoring execution parameters and comparing the measured parameters with the theoretically predicted ones

• Adaptivityall those techniques that can be used to automatically/autonomically adapt component behavior to grid changing features (faulty nodes and links, varying loads, unpredictable hot spots, etc.)

• Component run time supportconcerning the features/mechanisms needed to run components on grids as well as the (optimized) run time systems supporting component execution

• Component semanticsconcerning all the aspects related to the definition of formal and informal component and component compositions semantics

• Interoperabilitythat is all the problems related to the possibility to run component programs interacting constructively with non component software built according to existing grid standards as well as with component software developed according to different component models


27

JPA2: research groups

• Securitynot in the JPA (fault !) but we *must* take it into account

• Interaction with other CoreGRID work packages aimed at providing the other CoreGRID work packages with the results produced within WP3 by the research groups listed above and gathering requisites/requirements and suggestions from the other work packages, in particular from those that will eventually use the GCM or implement the Grid platforms aimed at supporting GCM. Within the M13 – M30 period, close interaction is expected with the other CoreGRID work packages so that both those institutes will consider using GCM in their specific activities. WP3 will also benefit from the suggestions/requirements coming from those work packages while refining/developing the GCM.

o Interaction with national/international standard institutes/committees aimed at promoting the results achieved within WP3 at different levels. We expect that during the M13 – M30 period the partners of WP3 will start participating in such institutes/committees activities and that partners of CoreGRID WP3 will participate in committees designing/defining new research frameworks at both national and international level.

GridCOMP STREP (INRIA leader, UNIPI, UOW, ISTI/CNR + … )provide reference/prototype implementation of GCM as ofD.PM.02 on top of existing, open source middleware

DFG research action proposed:

MetaGrid: Metadata and Metaprogramming for the Grid.German joint research action (DFG-Schwerpunktprogramm).Funding for 20+ researchers, 6 years, ~9M EUR,

granting decision expected in May 2006.Interaction with CoreGRID planned, WP3 initiators:

UNIPASSAU, WWU Muenster, ZIB (plus four others).

Positioning w.r.t. NGG reports (1&2)

Software view (with implications for architecture and user view) addressing:Programming grid through abstractions

GCM combines parallel & distributed programming practices in a coherent way

Invisible grid scenarioGCM implementation encapsulates all grid related concerns

dynamicity & heterogeneity handling, middlewareinterface, resource discovery & management, …

Self-* issuestargeted in the run time support / component framework

Currently going to be addressed Relationships/requirements on Network Centric OS

which features can be moved to OS ?


31

Positioning w.r.t. NGG3 (SOKUs)

NGG3 public in this period

moving from services to SOKUs (Service Oriented Knoweldge Utilities)

Still central point (research issue)raising the level of abstraction (programming

environments)

Comment from a referee: “what if components are no more trendy?”
