Dr. Harald Kornmayer g-Eclipse Crakov Grid Workshop 06

An integrated, Grid enabled workbench tool forGrid application users, Grid developers

and Grid operatorsbased on the Eclipse platform

Grid architecture blue print

• Well known:– Layered

– Different solutions available

• gLite

• UNICORE

• Globus

• …Fabrics (computation, storage, networks)

middleware

High level Grid services

Application services

User interfaces

• User interfaces– Most projects use a web server based approach for

user interfaces• http protocol have some limitations (request/response)


Fat vs thin client

Thin clients

• Only web browser needed

• No software on client required

• http protocol used

• Server required – Single point of entrance

• Examples: – GridSphere

• Standard computers grow

• Connectivity grows

• Tools for distributed software management exist

• More flexibility concerning protocols

• Examples: – Migrating Desktop

• User oriented

e-Science infrastructure

• Grid infrastructure are emerging– National level

• AustrianGrid• D-Grid• ….

– European level • EGEE• Deisa• …

– worldwide • LCG computing Grid• …

• Different Grid middleware exists– gLite, UNICORE, GT4, ….

i.e EGEE infrastructure in Europe


e-Science applications

• Many application domains starts using Grid infrastructures– Grid applications are

workflows

• Even a embarrassingly parallel task is a workflow!

– Grid applications access different computing systems

– Grid applications are written in different programming languages

– Errors are not easy to debug as the infrastructure can change all the time

JAVA, SQL, Linux

FortranLinux, OSF, AIX

C, Linux

C++, Linux

The g-Eclipse vision

• Many projects developed promising Grid tools• Each project had its own UI (portal) framework• Easy exchange of results was „impossible“• User centric approaches (application end user)

an integrated platform – Grid users– Grid operators– Grid application developers

• Based on an industry compliant open-source tool

The project

• Funded by European Union• 24 months

• approx. 2 M€ funding

• Specific targeted research project

• 6 Partners

Eclipse

• Started in 2001 – IBM donated their Java development framework as

Open Source

– Pure Java development

– First industrial partners joined

• Eclipse Foundation started in 2004– Independent non-profit organization

• Eclipse management organization

• Councils (requirements, architecture and planning)

• 10 projects (including > 50 subprojects)

– With Eclipse 3.0 not only a Java IDE, but a general framework build for extension


Grid user roles

• 3 different roles– user– operator– developer

• in general...– job management– resource management

• files• applications• ...

integration in Eclipse is complex

Status/First results

• First Architecture finished• Implementation started

– VO Management• Declare memberships• Manage identities/roles

– File browser• Knowledge from MD used

– Terminal access– JDL Editor started– …

• Collaboration – With Eclipse Foundation

• Proposed a technology project

– Collaboration with EGEE and int.eu.grid established


Summary

• g-Eclipse started 1st of July 2006• Architecture defined• Implementation of prototype version started

The following goals are addressed: • Creation of an “Creation of an “eco systemeco system” of tools to build Grid-” of tools to build Grid-
