2. Contents Where are we now? IeSE : DataPortal, HPCPortal, InfoPortal
Why use Portals?
Where are we going?
Portal Services : Web Services –> Grid Services

3. Overview
Grid and e-Science technologies to improve access to and integrate CLRC's facilities for the UK scientific research community.
Prototype projects, DataPortal and HPCGrid Portal.
Main components of these are being re-worked in a service-based environment which will conform to the Open Grid Services Architecture (OGSA) being developed by the Globus team and IBM.
Developments of middleware in the IeSE project will help us to support other projects, such as DIAMOND, NWGrid and HPCx, using emerging Grid technologies.

4. What is the DataPortal ?
Making existing scientific data resources accessible through a single interface.
Acting as a broker between scientists, facilities and data.

18. Why Use Portals ? Single point of access to remote resources
Sign on once – Run Anywhere
Increases security for end user and remote resources
Reduces potential firewall problems

19. IeSE Project
The Integrated e-Science Environment comprises DataPortal, InfoPortal and HPCPortal
Allows us to evaluate and deploy prototypes which may add value to the UK e-Science Grid

20. IeSE Functionality
The portals encapsulate functionality which adds value to the simple Grid pillars.
Globus pillar:
Value add:
single sign-on (GSI)
session management and role-based authorisation, expert system and ontologies
resource discovery (MDS)
monitoring, personal selection and brokering
file transfer (GridFTP and GASS)
database query and dataset location, replica management and QoS
job submission (GRAM and GRIP)
query based on application functionality, matching to resources and i/o format and content, workflow support

21. IeSE Applications
e-Science Pilot Projects, CCPs - strong science base! Projects are now running and using the re-usable software base of IeSE. Most funded by Research Council e-Science grants:
NERC Environment from the molecular level: An e-science proposal for modelling the atomistic processes involved in environmental issues;
BBSRC An E-Science Resource for High Throughput Protein Crystallography;
EPSRC and Core Programme e-Science Technologies in the Simulation of Complex Materials;
NERC Data Grid;
Core Programme UK e-Science Grid deployment project (Level 2 Grid)
Working with other CLRC departments and collaborators gives powerful science drive.

22. Where are we going ? Move towards a modular portal framework
Separation of presentation layer (e.g. web site / portal) from backend services
Implementation of backend services using web-services techniques and or grid-services as they develop

23. PHPNuke Portal Framework
PHPNuke is a Content Management System
Developed in PHP
Uses MySQL or similar backend database
Modular Dynamic Architecture
Configurable using Blocks and Modules
Inbuilt localisation
User customisable interface
