Background and Goals
• TeraGrid
• TeraGrid and Gateways (GEON)
• Gateways (GEON) and Education (NTC)
– TeraGrid Pathways project
Goal
To understand where gateways in general and GEON
and GISolve in particular might further Navajo
Tech’s research and education goals.

In under 15 minutes I hope to answer
• TeraGrid
– What is it?
• Gateways
– What are they? How are others using them?
I’d like you to think about what aspects of these
might be relevant for your work.

What is the TeraGrid?
A unique combination of fundamental CI components
Navajo Technical College, September 25,
2008
TeraGrid Resources Available for all Domain Scientists
At no cost to them!
• Funded by the National Science
Foundation for use by all the
nation’s scientists, engineers,
educators
• Integrated, persistent, pioneering
resources
– That you don’t have to maintain
• Gain new insights into the most
challenging research questions
and societal problems through
the use of cyberinfrastructure
• Advanced support
– Dedicated staff investment to
really make a difference on
complex problems

TeraGrid Gateway Program begins in 2004
• Web developments, explosion of digital data are
leading to the increased importance of the internet
and the web for science
– Only 16 years since the availability of web browsers
•Developments in web technology
–From static html to cgi forms to the wikis and social web pages of today
•Full impact on science yet to be felt
– Web usage model resonates with scientists
•But, need persistency if the Web is to have a profound
impact on science
Navajo Technical College, September 25,

Today, there are approximately 29
gateways using the TeraGrid
Navajo Technical College, September 25,

Not just ease of use
What can scientists do that they
couldn’t do previously?
• Linked Environments for Atmospheric Discovery
– Access to radar data
• National Virtual Observatory
– Access to sky surveys
• Ocean Observing Initiative
– Access to sensor data
• PolarGrid
– Access to polar ice sheet data
• Social Informatics Data Grid
– Analysis tools
• GridChem
– Developing multiscale coupling
• How would this have been done before gateways?

Gateways can further investments in
other projects
• Increase access
– To instruments, we’ll see an example today
• Increase capabilities
– To analyze data, we’ll see an example today
• Improve workforce development
– For underserved populations, we’ll see an example today
• Increase outreach
• Increase public awareness
– Public sees value in investments in large facilities
• Slice bread
• Pack the kids’ lunch, etc.

Gateways in the marketplace
Kids control telescopes and share images
• “In seconds my computer
screen was transformed
into a live telescopic view”
– “Slooh's users include newbies
and professional astronomers
in 70 countries”
• Observatories in the Canary
Islands and Chile, Australia
coming soon
• 5000 images/month since
2003
• Increases public support for
investment in these
facilities

Gateways Greatly Expand Access
• Almost anyone can investigate scientific questions using
high end resources
– Not just those in the research groups of those who request
allocations
– Gateways allow anyone with a web browser to explore
•Opportunities can be uncovered via google
–My 11-year-old son discovered nanoHUB.org himself while his class was studying
Bucky Balls
• Fosters new ideas, cross-disciplinary approaches
• Encourages students to experiment
• But used in production too
– Significant number of papers resulting from gateways including
GridChem, nanoHUB
– Scientists can focus on challenging science problems rather than
challenging infrastructure problems

TeraGrid Pathways
• NSF project to broaden participation in the
TeraGrid
– Building human capacity
•Mentoring, fellowships, new user support
– Gateways as an outreach mechanism
•Adapt gateways for educational use
–GEON , Navajo Tech
•Teach students how to build gateways
–PolarGrid , Elizabeth City State University
Navajo Technical College, September 25,

Navajo Tech, GEON, SRI
• Goals
– Use of gateways in the classroom as appropriate
•SRI expertise in using technology for learning
– Use of gateways to further faculty work
• August 11-15, Jason Ariviso, Mark Trebian attend
GEON Summer Institute

Follow-up telecon August 28
Enough excitement to warrant this visit!
• AutoCAD work with NASA, large terrestrial scan data that
must be subsetted
– Scan device at Cal-IT used to scan artifacts may be relevant
• Using geographic information systems (GIS) to create
accurate maps for agriculture, hydrology, mineral deposits
– GEON, GISolve work may be relevant
• Subset of GEON at NTC to store local data locally but share
the data through GEON
– NTC portal as a GEON portlet
– Faculty datasets
• Video production, archiving film
This 2-day meeting is a chance to expand on these
ideas.

PolarGrid
• Cyberinfrastructure Center
for Polar Science (CICPS)
– Experts in polar science,
remote sensing and
cyberinfrastructure
– Indiana, ECSU, CReSIS
• Satellite observations show
disintegration of ice shelves
in West Antarctica and
speed-up of several glaciers
in southern Greenland
– Most existing ice sheet
models, including those used
by IPCC cannot explain the
rapid changes

• Components of PolarGrid
– Expedition grid consisting of ruggedized laptops in a field grid linked
to a low power multi-core base camp cluster
– Prototype and two production expedition grids feed into a 17
Teraflops "lower 48" system at Indiana University and Elizabeth City
State (ECSU) split between research, education and training.
– Gives ECSU a top-ranked 5 Teraflop MSI high performance
computing system
• Access to expensive data
• High-end resources for analysis
• MSI student involvement

SCEC using gateway to produce hazard map
• PSHA hazard map for
California using newly
released Earthquake
Rupture Forecast
(UCERF2.0) calculated
using SCEC Science
Gateway
• Warm colors indicate
regions with a high
probability of experiencing
strong ground motion in the
next 50 years.
• High resolution map,
significant CPU use
Navajo Technical College, September 25,

Social Informatics Data Grid
• Heavy use of “multimodal”
data.
– Subject might be viewing a
video, while a researcher
collects heart rate and eye
movement data.
• Events must be
synchronized for analysis,
large datasets result
• Extensive analysis
capabilities are not
something that each
researcher should have to
create for themselves.

When might a gateway be appropriate?
• Researchers using defined sets of tools in different ways
– Same executables, different input
•GridChem, CHARMM
– Creating multi-scale or complex workflows
– Datasets
• Common data formats
– National Virtual Observatory
– Earth System Grid
– Some groups have invested significant efforts here
•caBIG, extensive discussions to develop common terminology and formats
•BIRN, extensive data sharing agreements
• Difficult to access data/advanced workflows
– Sensor/radar input
•LEAD, GEON
• Support available to help build gateways

Tremendous Potential for Gateways
• In only 16 years, the Web has
fundamentally changed human
communication
• Science Gateways can leverage
this amazingly powerful tool to:
– Transform the way scientists
collaborate
– Streamline conduct of science
– Influence the public’s perception
of science
• Reliability, trust, continuity are
fundamental to truly change the
conduct of science through the
use of gateways
– High end resources can have a
profound impact
• The future is very exciting!
