Title: The WUN Grid
1The WUN Grid
An infrastructure for collaborative research in
the Worldwide Universities Network
Presented by David De Roure and Allison Clark
2Grid Computing
- Roots in high performance computing and
specialized scientific problem-solving - Grid computing has emerged as a powerful general
purpose infrastructure to enable new research and
learning - Its contemporary definition by Foster Kesselman
is -
- A Grid brings together core grid computing
infrastructure services, applications and users
Coordinated resource sharing and problem solving
in dynamic, multi-institutional virtual
organizations
3International Grid Scene
- The Global Grid Forum brings theinternational
community together - UK and European activities emphasize the Semantic
Grid, which promotes all aspects of
interoperability - UK e-Science program attracts attention forbeing
applications-led and multidisciplinary - Investment for sustainable infrastructure
evident - e.g. NSF Middleware Initiative, OMII
- In practice there are many grids
- organizational barriers impede creation of
general purpose international Grids
4WUN and Grid Synergy
- WUN will benefit from new collaborative research
enabled by applications on the Grid - The WUN Grid will benefit from the organizational
infrastructure provided by WUN - WUN easily overcomes institutional barriers which
constrain other Grids - WUN Grid is competitive against other Grid
exercises - Hence WUN Grid offer significant enhancement for
WUN with prospect of high impact, competitive
research - Gives WUN an identifiable infrastructure and a
unique platform for basis of funding applications
5Excellent circumstances
- WUN partners include international leaders in
Grid computing - e.g. San Diego Supercomputer Centre at UCSD,
National Centre for Supercomputing Applications
at UIUC, key Grid software from Wisconsin,
CiteSeer at Penn State - All UK WUN partners are major players in
e-Science, with significant international
leadership - White Rose Grid provides track record in creating
a multi-institutional grid - Many WUN Grand Challenges will benefit from Grid
computing - WUN Grid is itself a Grand Challenge and it
supports other WUN Grand Challenges
6Strategy
- Move towards vision of a WUN Grid which
- Creates new, high-impact research
- Generates IP and learning enhancements
- Generates revenue
- Is sustainable
- Consult users and identify priority areas where
WUN Grid is positioned to make an impact - Create an implementation plan for WUN Grid,
balancing data, collaboration and computation - Implement a foundation WUN Grid and example
grassroots applications to inform the WUN Grid
roadmap

- Computational Grid
- Second meeting in Santa Clara December 2003,
hosted by Sun - Agreed governance structure
- Created infrastructure and applications teams
- Have produced
- What document
- How document
- Prototype grid
- Work has gone to schedule WUN works

10Arts and Humanities
- Emerging activity in US and UK
- Link with HASTAC - Humanities, Arts, Science, and
Technology Advanced Collaboratory - strategic alliance of scientists, humanists,
artists, social theorists, legal specialists, and
information technology specialists - Link with UK Arts and Humanities Research Board
and Arts and Humanities Data Service - Link with GGF
- Humanities, Arts and Social Sciences Research
Group - Workshop on Social Factors, Humanities, Arts and
Social Sciences Old Challenges and New
Disciplines for Grid Computing
11HASTAC Humanities, Arts, Science and Technology
Advanced Collaboratory
- How much the scientist can learn from the
humanist and artist and vice versa. - Humanist can add the why to the gee whiz part
of the technology. Historians and philosophers on
one side of campus. Computer scientist and
engineers on the other. No more build it and they
will come. - The challenge is the building of bridges among
diverse cultures and communities technology,
humanist, artists, social scientist. - Speak a common language
12HASTAC Founding Members

13HASTAC maybe Mission Statement
- HASTAC is an international, interdisciplinary
consortium which seeks to create, develop,
advance and utilize a broad range of leading
computing and information systems while
contributing to an understanding of the
interconnections between the human sciences,
natural sciences, arts, and technology in a
complex global society. HASTAC, in partnership
with the science and technology communities, is
dedicated to the creation and development of
humane technologies and technological humanism.
14Cyberinfrastructure Enables People
Scientists, Engineers, Decision Makers, Policy
Makers, Media and Citizens Engaging in
discovery, analysis, discussion, deliberation,
decisions, policy formulation and communication
Collaboration Framework facilitates Idea and
Knowledge Sharing, eLearning and Multi-Objective
Decision Support Processes
Analysis Framework facilitates Data and Model
Discovery, Exploration, and Analysis via the
Collaboration Framework
Data Management Framework builds logical maps of

15Music demonstrator
- Activities underway
- Access Grid being enhanced for musical
performance - Collaboration between music information retrieval
experts at UIUC and WUN Grid - Semantic Web collaboration tools, including
capture and replay, being applied to musical
performance - Example
- Convert digitized musical recording into musical
score - Requires polyphonic pitch transcription
(computational challenge) - Use this for search in music information
retrieval (data challenge) - Use for re-synthesis
16Accessing musical content
17Polyphonic pitch transcription
18WUN collaborative Grid
- Proven technology from
- UK Advanced Knowledge Technologies
Interdisciplinary Research Collaboration (won
Semantic Web Grand Challenge) - Link with CiteSeer (Giles) at Penn State
- Proposing AKTive Seer to run on WUN Grid as
collaboration tool for WUN - Supports communities of practice
- Matchmaking between WUN experts
- Infrastructure challenge
- Involves integrating terabytes of data
19AKTive Seer
20Social Sciences

- Urbana, UCSD, Manchester, hold massive data
collections - Taking advantage of the e-social science
opportunities - Demonstrator (Leeds) Hydra International
- Finds groups of similar cities across UK, US,
France and Norway - e.g. could be used in a comparative analysis of
planning policies between similar cities across
international boundaries
21Hydra
22Geospatial digital library
- From Santa Clara meeting
- Builds on DialogPlus
- Discussing using Southampton tools with
Alexandria Digital Library content
23Earth Science Grand Challenge
- Long-term potential for using WUN Grid
- Fibre-optic links ashore followed by high-speed
high-bandwidth communications provide live video
feed from hydrothermal vent-sites to the
classroom - Command capability provides pan and tilt controls
on video cameras, continuous monitoring of
temperature changes etc. - Remote manipulation using robot arm
24Summary
- Creation of WUN Grid offers very significant
benefits to WUN in terms of synergising resources
for research impact - Considerable progress in 3 months
- Roadmap agreed by WUN Informatics Group in Santa
Clara - Arts and humanities application area have held
