Today’s “Computer”
• . . . is a coordinated set of hardware, software, and services, all integrated and working together
• This collection of computers, data, sensors, handheld devices, services, and other technologies team together to form cyberinfrastructure (abbreviated “CI”)

CI Shares Distributed Tools
• “Grid” Computing “takes the parallel
computer out of the box”
• CPUs can be in different geographical locations
• Grids connect many different kinds of components, users, and data
NVO analysis can involve connecting the telescope, data
archive, and computer through grid computing

Science GatewaysCommunity-led initiative for the TeraGrid
http://www.teragrid.org/programs/sci_gateways/
Research communities build their own cyberinfrastructure.
• Gateways must allow heterogeneity of:• Resources - diverse architectures at local, national, int’l. levels
• Users- from HPC expert to K-12 student… all should benefit from CI
• Software stacks, policies
• Working with Gateways, TeraGrid will start to provide generic CI services to research communities.
• Goal: Integration and interoperability

Education Programs
SAN DIEGO SUPERCOMPUTER CENTER
August 2007
“HPC University”• Advance researchers’ HPC skills
• Catalog of live and self-paced training• Schedule series of training courses• Gap analysis of materials to drive development
• Work with educators to enhance the curriculum• Search catalog of HPC resources• Schedule workshops for curricular development• Leverage good work of others
• Offer Student Research Experiences• Enroll in HPC internship opportunities• Offer Student Competitions
• Publish Science and Education Impact• Promote via TeraGrid Science Highlights, iSGTW• Publish education resources to NSDL-CSERD
SAN DIEGO SUPERCOMPUTER CENTER
On-demand education in the TeraGrid
• Online TeraGrid training portal• synchronous/asynchronous• Interactive Flash Video
•Account-based•Built-in user tracking
•Constructivist learning
SAN DIEGO SUPERCOMPUTER CENTER
If TeraGrid is for all, who is left out?
• Scientists with low bandwidth connectivity
• Schools without broadband internet connections
• Students without access at home or at school
This is NOT ok !

HPWREN – High Performance Wireless Research and Education Network
• http://hpwren.ucsd.edu/
The High Performance Wireless Research and Education Network (HPWREN) is a National Science Foundation funded network research program, which also functions as a collaborative cyberinfrastructure for
research, education, and first responder activities.
Research activities include creating, demonstrating, and evaluating a non-commercial, prototype, high-performance, wide-area, wireless
network in San Diego, Riverside, and Imperial counties.
The network includes backbone nodes at the UC San Diego and San Diego State University campuses, and a number of "hard to reach"
areas in remote environments.
SAN DIEGO SUPERCOMPUTER CENTER
HPWREN technology was used to create the Tribal Digital Village Network (TDVNet), which now connects most of
the 20 tribal bands in Southern CA• http://hpwren.ucsd.edu/news/001018.html
The first TDVNet tower was built by tribal members who learned how by working with Hans-Werner Braun
(HPWREN Principal Investigator) and his staff. The first group, from the Pala Reservation, then taught members of other bands how to do it. Today, TDVNet serves the community and has allowed numerous internet-based
small business initiatives to sprout on reservation lands.

The Vision * for: Internet to the Hogan and Diné Grid:
• Bring Expanding Educational Opportunities to the Navajo Nation
• Build an educated workforce to support scientific research, innovation, and economic growth
• Connect Navajo people to one another and to others
• Create opportunities for national and world leadership for Navajos in helping to solve global challenges of the future.

Challenges: Community Support
SAN DIEGO SUPERCOMPUTER CENTER
The Navajo Tech team is gathering the essential ingredients for success:
• Collaboration with national research and education colleagues through TeraGrid, UNM, SDSC, National University, and professional organizations
• Collaboration with industry partners for internships, support, and joint entrepreneurial endeavors
• Multi-disciplinary and Integrated Curriculum
• Online Education (Hybrid e-Learning, Internet-based, Mentoring, and Workshops)
• Research opportunities at multiple sites
• Global Knowledge-sharing through professional gatherings and on-line community communications
SAN DIEGO SUPERCOMPUTER CENTER
Internet to the Hogan and Diné Grid project brings to the reservation . . .
• Education and Research opportunities that are collaborative, creative, engaging, stimulating, and connected to meaningful community-relevant needs.
• Lifelong learning and cultural preservation tools and opportunities for the entire community
• Academic recognition that is credible, respected, and innovative within national academia.
• Undergraduate and graduate degree programs that are project-based, relevant to the Navajo Nation, and include collaborative and web-based extended learning courses and certificate programs.
SAN DIEGO SUPERCOMPUTER CENTER
What do we expect from technology?
• Diné Grid technologies as easy to use as your car:
• Components working together to provide end-to-end performance for all users.
• Technology that works basically how you expect it to work, regardless of where you are.
• Instruction that’s user friendly
• Someone nearby to fix it when it breaks
• Because it’s more about where you’re going than how it works
CI: a tool for creating your own pathway

How does that affect teaching?
• Educators must build a strong foundation of understanding the underlying concepts:
• Data – understanding the stories from the evidence (e.g. using visualization tools)
• Teamwork – understanding and appreciating one another’s strengths and contributions
• Connections – communication builds learning through shared investigation and discovery
• Parallelism – breaking down overwhelming challenges and sharing the work among many
