e-Business e-Science and the Grid
  • e-Business captures an emerging view of
    corporations as dynamic virtual organizations
    linking employees, customers and stakeholders
    across the world.
  • The growing use of outsourcing is one example
  • e-Science is the similar vision for scientific
    research with international participation in
    large accelerators, satellites or distributed
    gene analyses.
  • The Grid integrates the best of the Web,
    traditional enterprise software, high performance
    computing and Peer-to-peer systems to provide the
    information technology infrastructure for
    e-moreorlessanything.
  • A deluge of data of unprecedented and inevitable
    size must be managed and understood.
  • People, computers, data and instruments must be
    linked.
  • On demand assignment of experts, computers,
    networks and storage resources must be supported

5
So what is a Grid?
  • Supporting human decision making with a network
    of at least four large computers, perhaps six or
    eight small computers, and a great assortment of
    disc files and magnetic tape units - not to
    mention remote consoles and teletype stations -
    all churning away. (Licklider 1960)
  • Coordinated resource sharing and problem solving
    in dynamic multi-institutional virtual
    organizations
  • Infrastructure that will provide us with the
    ability to dynamically link together resources as
    an ensemble to support the execution of
    large-scale, resource-intensive, and distributed
    applications.
  • Realizing thirty year dream of science fiction
    writers that have spun yarns featuring worldwide
    networks of interconnected computers that behave
    as a single entity.

6
e-Science
  • e-Science is about global collaboration in key
    areas of science, and the next generation of
    infrastructure that will enable it. This is a
    major UK Program
  • e-Science reflects growing importance of
    international laboratories, satellites and
    sensors and their integrated analysis by
    distributed teams
  • CyberInfrastructure is the analogous US initiative

e-Business and (Virtual) Organizations
  • Enterprise Grid supports information system for
    an organization includes university computer
    center, (digital) library, sales, marketing,
    manufacturing
  • Outsourcing Grid links different parts of an
    enterprise together (Gridsourcing)
  • Manufacturing plants with designers
  • Animators with electronic game or film designers
    and producers
  • Coaches with aspiring players (e-NCAA or e-NFL
    etc.)
  • Customer Grid links businesses and their
    customers as in many web sites such as amazon.com
  • e-Multimedia can use secure peer-to-peer Grids to
    link creators, distributors and consumers of
    digital music, games and films respecting rights
  • Distance education Grid links teacher at one
    place, students all over the place, mentors and
    graders shared curriculum, homework, live
    classes

9
Some Important Styles of Grids
  • Computational Grids were origin of concepts and
    link computers across the globe high latency
    stops this from being used as parallel machine
  • Knowledge and Information Grids link sensors and
    information repositories as in Virtual
    Observatories or BioInformatics
  • More detail on next slide
  • Community Grids focus on Grids involving large
    numbers of peers rather than focusing on linking
    major resources links Grid and Peer-to-peer
    network concepts
  • Semantic Grid links Grid, and AI community with
    Semantic web (ontology/meta-data enriched
    resources) and Agent concepts

Information/Knowledge Grids
  • Distributed (10s to 1000s) of data sources
    (instruments, file systems, curated databases )
  • Data Deluge 1 (now) to 100s petabytes/year
    (2012)
  • Moores law for Sensors
  • Possible filters assigned dynamically (on-demand)
  • Run image processing algorithm on telescope image
  • Run Gene sequencing algorithm on compiled data
  • Needs decision support front end with what-if
    simulations
  • Metadata (provenance) critical to annotate data
  • Integrate across experiments as in
    multi-wavelength astronomy

Data Deluge comes from pixels/year available

Grids in a Nutshell
  • Grids are by definition the best of HPCC, Web
    Services, Agents, Distributed Objects,
    Peer-to-peer networks, Collaborative environments
  • Grid applications are typically zero or one very
    large supercomputers, lots of conventional
    machines, with unlimited data and/or people
    supporting an electronic (virtual) community
  • Data sources and people are latency tolerant
  • Multiple supercomputers (or clusters) on same
    Grid as in TeraGrid/ETF largely for sharing of
    data and by people
  • Grids are supported by Global Grid Forum, W3C,
    OASIS setting standards
  • Grids are a service oriented architecture
    hiding irrelevant details
  • Services are electronic resources communicating
    by messages
  • Message based architecture gives scalable loosely
    coupled component model

16
A typical Web Service
  • In principle, services can be in any language
    (Fortran .. Java .. Perl .. Python) and the
    interfaces can be method calls, Java RMI
    Messages, CGI Web invocations, totally compiled
    away (inlining)
  • The simplest implementations involve XML messages
    (SOAP) and programs written in net friendly
    languages like Java and Python

    (portlets)
  • Application Grids for Earth Science/Biocomplexity/
    supercomputer users
  • Integration of handheld devices with the Grid
  • Audio-video conferencing and collaboration with a
    Grid architecture
  • Multimedia on the Grid http//www.undergroundfilm

Why Grids for Education
  • Education is a classic distributed organization
  • New multi-disciplinary curricula in emerging
    fields (information technology, informatics,
    biocomplexity, nanotechnology) require
    distributed experts interacting with mentors and
    students
  • Grids support component model for content
    allowing re-use of research services in education
  • Education fits the service model for both
    process and Curriculum
  • Education wants rich integration of data sources
    and people and some computing Grids can do this
  • Grids democratize resources as enable universal
    (ubiqitous) access
  • In terms of geographic distribution, level (K-12
    through lifelong learning) and disparate clients
  • Grids support the Internet generation
  • WebCT, Blackboard, Placeware, WebEx, Groove,
    Learning Management systems all have natural Grid
    implementations

Grid Learning Model
  • Education and Research Grids share some services
    both for content and process
  • For example collaboration services are largely
    identical
  • Research will use much larger simulation engines
    to get high resolution results
  • Maybe a researcher uses a CAVE to visualize
    education a Macintosh
  • But both can share data services but run through
    different filters to select for precision
    (research) or pedagogical value (education)
  • Education has digital textbook frontend to
    resources of the research Grid
  • Both use same workflow technologies to link
    services together

22
Grid Services for the Education Process
  • Learning Object XML standards already exist
  • Registration
  • Performance (grading)
  • Authoring of Curriculum
  • Online laboratories for real and virtual
    instruments
  • Homework submission
  • Quizzes of various types (multiple choice, random
    parameters)
  • Assessment data access and analysis
  • Synchronous Delivery of Curricula including
    Audio/Video Conferencing and other synchronous
    collaborative tools as Web Services
  • Scheduling of courses and mentoring sessions
  • Asynchronous access, data-mining and knowledge
    discovery
  • Learning Plan agents to guide students and
    teachers

23
Implementing Grids for Education I
  • Need to design a service architecture for
    education
  • Build on services from broader fields
  • Need some specific EducationML specifying
    services and properties
  • Note IMS (http//www.imsproject.org/) and ADL
    have a lot of education property metadata but no
    services
  • Need more use of standards outside education but
    much of IMS can be used
  • Use services where-ever possible but only if
    coarse-grain

24
Implementing Grids for Education II
  • Build a Education Grid prototype addressing
    content and process
  • Focus education grid on a curriculum area (using
    Grids!) such as Geoscience or even
    e-Science/Information Technology/Science
    Informatics
  • Re-use Grid services in systems area (portals,
    security, collaboration ..) and from application
    domain
  • What research Grid services can be re-used what
    need to be significantly changed or customized
  • Develop some Education process services
  • Supply leadership in use of CyberInfrastructure/Gr
    ids in education
  • Feed Education needs to CyberInfrastructure and
    vice-versa
  • Perform a requirement analysis analogous to Gap
    Analysis http//grids.ucs.indiana.edu/ptliupages/p
    ublications/GapAnalysis30June03v2.pdf
  • Develop curriculum in Grids, e-Science and
    CyberInfrastructure

25
Conclusions
  • Grids/CyberInfrastructures are inevitable and
    pervasive
  • Education can benefit from Grids and vice-versa
  • Can expect Web Services, P2P networks and Grids
    to merge with a common set of general principles
    but different implementations with different
    scaling and functionality trade-offs
  • We will be flooded with data, information and
    purported knowledge
  • One should be preparing Grid strategies
    understanding relevant Web and Grid standards and
    developing new domain specific standards
  • Note many existing (standards) efforts assume
    client-server and not a brokered service model
    these will need to change!
  • Enough is known that one can start today with
    prototypes

26
Discussion
  • The following additional points were made in
    discussion
  • Connect to Citizen Science as at
    http//www.ebird.org and projects like SETI_at_Home
  • Role of Science museums on a Grid
  • Role of Grid services to provide knowledge
    transformations for education or research
  • Use resources-on-demand and so knowledge
    broadly available if resources supplied as a
    national facility
  • Does Grid technology enhance or mitigate the
    digital divide
  • Need to explain role of teachers in an Education
    Grid and train them to take it
  • Explain difference between Internet and the Grid
  • Describe role of Access Grid type technology
  • Some new textbooks have embedded URLs
