What do we mean by Cyberinfrastructure (CI)?

SACNAS 2007Cyberinfrastructure: Changing the Face of

Science and Engineering


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”)

Engineering Grid

Using high-performance network connections, the TeraGrid integrates high-performance computers, data resources and tools, and high-end experimental facilities around the country. These integrated resources include more than 102 teraflops of computing capability and more than 15 petabytes (quadrillions of bytes) of online and archival data storage with rapid access and retrieval over high-performance networks. Through the TeraGrid, researchers can access over 100 discipline-specific databases. With this combination of resources, the TeraGrid is the world's largest, most comprehensive distributed cyberinfrastructure for open scientific research.TeraGrid is coordinated through the Grid Infrastructure Group (GIG) at the University of Chicago, working in partnership with the Resource Provider sites: Indiana University, Oak Ridge National Laboratory, National Center for Supercomputing Applications, Pittsburgh Supercomputing Center, Purdue University, San Diego Supercomputer Center, Texas Advanced Computing Center, and University of Chicago/Argonne National Laboratory.

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


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


On-demand education in the TeraGrid

• Online TeraGrid training portal• synchronous/asynchronous• Interactive Flash Video

•Account-based•Built-in user tracking

•Constructivist learning


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.


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 - Getting There


Challenges - Power Supply


Challenges: Community Support


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


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.


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


Thank you!



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
