IT This year in DoD The president’s fiscal 2006 Defense Department budget proposal
calls for raising IT spending by the largest margin in the past four years.
President Bush asked Congress to approve $30.1 billion for IT programs next year, a 4.9 percent increase over this year.
“The 2006 budget supports substantial investments in advanced technology to provide advantages over our enemies, particularly in remote sensing and high-performance computing,” Defense officials noted in a summary of IT spending. “Investments in communications are improving connectivity between troops and their commanders well beyond the field of battle. These developments are improving our ability to detect and counter the broad range of threats facing the United States, reaping benefits for both U.S. forces and homeland security.”
The proposal includes significant increases for several programs that are part of the Global Information Grid, …..

Features of NCOW GiG Global Information Grid is the Infrastructure NCOW Network Centric Operations and Warfare is
the architecture (DoD’s OGSA) Order of magnitude larger than GGF set of
specifications of (application) services (not in WSDL) Interesting principles such as all messaging
publish/subscribe OHIO: Only handle Information Once Post Information before and after processing (store raw
and processed data) Smart information pull (User defined operational
picture UDOP) No discussion of execution (computing) – largely
streaming information

Why Grids for NCOW? Web services gives us interoperability but Grids are
essential as we aim at Information Management Grids are the key idea to manage complexity but
applying uniform policies and building managed systems
Grids of Grids allows one to build out the management in a modular fashion
Uniform Grid messaging handles complex networks with managed QoS such as real-time constraints
Managed Services and Messaging gives scalability and performance
DoD found Web services were “undisciplined” (as used for say JBI) and need structure from Grids

Grids for Minority Serving Institutions (MSI) MSICII Minority - Serving Institutions Cyberinfrastructure (CI)
Institute led by Alliance for Equity in Higher Education• HACU Hispanic Association of Colleges and Universities• NAFEO National Association for Equal Opportunity in Higher Education• AIHEC American Indian Higher Education Consortium• Together represent 335 MSIs for three major minority groups in USA• I am Visiting Scholar for Cyberinfrastructure Development at the
Alliance• http://www.educationgrid.org
Democracy through Cyberinfrastructure (for which Grids are technology)• Enable broad (systemic) participation in leading edge
business, research and education irrespective of geography and local environment scalable to all MSIs
• Help preserve indigenous nations such as American Indian Nations and create jobs in geographically isolated locations – note unemployment in Navajo Nation is over 40%
1111
Minority - Serving Institutions Cyberinfrastructure Institute
Vision: To significantly increase the number of traditionally underrepresented minority scientists, engineers, educators and students that use, support, deploy, develop, and design CI.
Mission: Build and enhance meaningful collaborations between MSIs and the nation’s CI initiatives to ensure that necessary resources are available to develop and support their faculty and technical staff to become members of the national e-science community of practice.
Strategy: Link organizations representing all the MSIs with the experts in Cyberinfrastructure• Collaborate with NCSA, SDSC, TeraGrid ….
1212
MSICII Activities Training and Education at Research, Education,
Executive and Systems support levels Mentored internships and e-Science projects linking
PIs in MSI and nonMSI institutions Collaboratory/Portal including Science Gateways as in
TeraGrid Access to Cyberinfrastructure from MSIs building on
earlier AN-MSI project Provision of Cyberinfrastructure both at MSIs and
virtually (with Ian Foster’s help) as part of Nationally run facilities

Defining a Grid Grids support Sensors and Decision making Grids support Communities and Collaboratories There are many other Grid examples Grids consist of Organized Internet scale distributed
services
