The TeraGrid Facility
  • Grid Infrastructure Group (GIG)
  • University of Chicago
  • TeraGrid integration, planning, management,
    coordination
  • Resource Providers (RP)
  • Currently NCSA, SDSC, PSC, Indiana, Purdue, ORNL,
    TACC, UC/ANL
  • Additional RPs in discussion
  • Systems (resources, services) support, user
    support
  • Provide access to resources via policies,
    software, and mechanisms coordinated by and
    provided through the GIG.
  • The Facility
  • An integrated set of HPC resources providing NSF
    scientists with access to resources and
    collections of resources through unified user
    support, coordinated software and services, and
    extensive documentation and training.
  • The Federation
  • Interdependent partners working together under
    the direction of an overall project director, the
    GIG PI.

TeraGrid Objectives
  • DEEP Science Enabling Terascale Science
  • Make Science More Productive through an
    integrated set of very-high capability resources.
  • WIDE Impact Empowering Communities
  • Bring TeraGrid capabilities to the broad science
    community.
  • OPEN Infrastructure, OPEN Partnership
  • Provide a coordinated, general purpose, reliable
    set of services and resources.

6
Science GatewaysA new initiative for the TeraGrid
  • Increasing investment by communities in their own
    cyberinfrastructure, but heterogeneous
  • Resources
  • Users from expert to K-12
  • Software stacks, policies
  • Science Gateways
  • Provide TeraGrid Inside capabilities
  • Leverage community investment
  • Three common forms
  • Web-based Portals
  • Application programs running on users' machines
    but accessing services in TeraGrid
  • Coordinated access points enabling users to move
    seamlessly between TeraGrid and other grids.

TeraGrid Facility Today
Common TeraGrid Computing Environment
Local Value-Added User Environment
Heterogeneous Resources at Autonomous Resource
Provider Sites
  • A single point of contact for help
  • Integrated documentation and training
  • A common allocation process
  • A common baseline user environment
  • Services to assist users in harnessing the right
    TeraGrid platforms for each part of their work,
  • Enhancements driven by users.
  • Science Gateways to engage broader communities

Social and Behavioral Science Gateway
For social and behavioral scientists, comparing
apples to oranges is essential. Understanding
neural, cognitive, and social behaviors can
depend on the ability to uncover coherent
patterns among disparate data collected at
different times and places. Researchers correlate
subjects videotaped reactions with eye
movements, heart rates, electroencephalogram
results, and answers to written surveys. Its
complicated, says Chicago psychologist Bennett
Bertenthal, and technological infrastructure has
not kept pace with research needs.So Bertenthal
and a multidisciplinary team of more than a dozen
scientists from Chicago, Argonne National
Laboratory, and the University of Illinois at
Chicago are working to develop a set of
cybertools to help collect and analyze behavioral
data, collaborating with the TeraGrid Science
Gateways Program.
Central to the projectfunded with 2 million
from the National Science Foundationis the
Social Informatics Data (SID) Grid, a vast and
sophisticated warehouse of readings and
measurements meant to foster collaboration and to
spur the development of standards for gathering
and coding datawhich, Bertenthal says, right
now is not part of the landscape. In two years,
when the SID Grid is complete, psychologists,
sociologists, anthropologists, economists, and
neuroscientists can share notes across the globe
and use software interfaces like the ones shown
above to synthesize numerous forms of streaming
data at once.

Science Gateways
  • Independent infrastructure using TeraGrid
    resources in back-end fashion
  • Local gateway user management, authentication,
    authorization
  • Service Oriented Architecture using TeraGrid via
    web services such as job submission, file
    movement, authorization, job tracking and audit,
    etc.
  • Current Status
  • 15 prototypes at various stages of local
    production (some new gateways, most are
    operational with local services, early versions
    of TeraGrid-enabled services)
  • Developing scalable model to allow for many
    independent gateways, using standard TeraGrid
    services interfaces, with gateway-managed
    TeraGrid computational and storage allocations.
