Tele-Immersion and CAVERNsoft

• Tele-Immersion requires expertise in graphics, VR, audio/video compression, networking, databases

• Rapidly build new tele- immersive applications

• Retro-fit old applications

• CAVERNsoft enables applications!


CAVERNsoft uses Grid Software

• The Grid is a global software development effort to enable the use of high-performance networks like Abilene (Internet2), APAN, SURFnet, etc.

• Grids are changing the way we do science and engineering: computation to large-scale data

• Grids are designed to schedule, allocate, authenticate and manage advanced networking, computing and collaboration services on [optical] networks.

Cyber InfrastructureNSF Computer and Information Science Directorate (CISE)

• NSF is proposing a “Cyber Infrastructure” initiative – fund a number of Major Research Equipment (MRE) facilities that require a similar distributed storage and networked computing information infrastructure.

• Large MRE projects are the result of strategic planning by the broad university research community.

• NSF FY 2001 Budget Request to Congress: $138,540,000.

EarthscopeNSF Major Research Equipment

• USArray: a dense array of high-capability seismometers to be deployed throughout the US to improve our resolution of the subsurface structure.

• San Andreas Fault Observatory at Depth (SAFOD): a 4km-deep hole into the San Andreas fault zone close to the hypocenter of the 1966 M~6 Parkfield earthquake, to access a major active fault at depth

• To provide input to NSF’s Network for Earthquake Engineering Simulation (NEES) project that studies the response of the built environment to earthquakes.

EarthScope: USArray and SAFOD$ 74.81M FY01-04 NSF support requested• NSF, USGS, NASA Consortium

EarthScope will bring real-time Earth Science data to our desktops, to provide unprecedented opportunities to unravel the structure, evolution, and dynamics of the North American continent, and to better understand earthquakes and fault systems, volcanoes and magmatic processes, and links between tectonics and surfical processes.


Network for Earthquake Engineering Simulation NSF Major Research Equipment

http://www.neesgrid.org/http://www.evl.uic.edu/cavern/TIDE/SeattleQuake2001/

Network for Earthquake Engineering Simulation (NEES)$ 81.8M FY01-04 NSF support requested • Scoping study managed by NCSA; sponsored by NSF

• NEES will provide a networked, national resource of geographically-distributed, shared-use, next-generation, experimental research equipment installations, with tele-observation and tele-operation capabilities.

• NEES will shift the emphasis of earthquake engineering research from current reliance on physical testing to integrated experimentation, computation, theory, databases, and model-based simulation using input data from EarthScope and other sources.

• NEES will be a collaboratory – an integrated experimental, computational, communications, and curated repository system, developed to support collaboration in earthquake engineering research and education.


Terascale Computing SystemsNSF Major Research Equipment

http://www.nsf.gov/cgi-bin/getpub?nsf0151http://www.psc.edu/machines/tcs/status/

Terascale Computing Systems$ 136M FY00-02 NSF support requested • Distributed Terascale System to be awarded in June 2001; PSC Terascale awarded 2000

• As part of the ITR initiative, the Terascale project enables US researchers to gain access to leading-edge computing capabilities.

• The project is aligned with NSF’s Partnerships for Advanced Computational Infrastructure (PACI) initiative, and is coordinated with other agencies, such as DOE, to leverage the software, tools, and technology investments.

• The two Terascale Computing Systems will receive regular upgrades to take advantage of technology trends in speed and performance while providing the most advanced, stable systems possible to the research users.


• 10 geographically distributed observatories nationwide to serve as national research platforms for integrated, cutting-edge research in field biology

• To enable scientists to conduct experiments on ecological systems at all levels of biological organization – from molecular genetics to whole ecosystems, and across scales – from seconds to geological time, and from microns to regions and continents.

• Observatories will have scalable computation capabilities and will be networked via satellite and landlines – to each other and to specialized facilities, such as supercomputer centers.

• By creating one virtual installation via a cutting-edge computational network, all members of the field biology research community will be able to access NEON remotely.

Atacama Large Millimeter ArrayNSF Major Research Equipment

• Prior to developing ALMA, the US conceived the MMA as an aperture-synthesis radio telescope operating in the wavelength range from 3 to 0.4 mm.

• ALMA will be the world’s most sensitive, highest resolution, millimeter-wavelength telescope. It will combine an angular resolution comparable to that of the Hubble Space Telescope with the sensitivity of a single antenna nearly 100 meters in diameter.

• ALMA will consist of no less than 64 12-meter antennas located at an elevation of 16,400 feet in Llano de Chajnantor, Chile

Atacama Large Millimeter Array (ALMA),an expanded Millimeter Array (MMA)$ 32M FY98-01 NSF support requested for Design and Development• US: National Radio Astronomy Observatory and Associated Universities, Inc. with NSF funding• Europe: European Southern Observatory, Centre National de la Recherche Scientifique, Max-Planck-

Grid Physics Network

• Team of physicists and computer scientists who plan to implement Petascale Virtual Data Grids (PVDGs) computational environments for data-intensive science

• Four physics experiments – CMS, ATLAS, LIGO, SDSS –share common challenges: massive datasets, large-scale computational resources and diverse communities of thousands of scientists spread across the globe

– The LHC CMS and ATLAS experiments will search for the origins of mass and probe matter at the smallest length scales

– LIGO will detect the gravitational waves of pulsars, supernovae and in-spiraling binary stars

– SDSS will carry out an automated sky survey enabling systematic studies of stars, galaxies, nebula, and large-scale structure

• GriPhyN estimates 20 Tier 2 sites (6 CMS, 6 ATLAS, 5 LIGO and 2 SDSS), with a projected five-year cost of ~$85M-90M, half of which is for hardware
