What is cyberinfrastructure? A coordinated set of hardware, software, and services, all integrated and working together. “CI” encompasses networks, computers, data, sensors, handheld devices, other technologies, and the services or human “glue” that holds them all together. network data computer storage field instrument network computer data network computer viz computer sensors field data wireless The “computer” as an integrated set of resources

What is TeraGrid? Supported by National Science Foundation World’s largest distributed cyberinfrastructure for scientific research Integrated high performance computers, data resources, experimental facilities provide coordinated, reliable performance. Annual Science Highlights publication is good overview of projects supported by TeraGrid

How can I get started? TeraGrid resources are free to NSF-supported academic researchers and educators Education and Startup requests through TG Web site –up to 250,000 hours of time (depending on resource) –processed quickly (usually within 2 weeks) Development Allocations Committee (DAC) for start-up accounts up to 30,000 hours of time are requests processed in two weeks - start-up and courses Medium Resource Allocations Committee (MRAC) for requests of up to 500,000 hours of time are reviewed four times a year Large Resource Allocations Committee (LRAC) for requests of over 500,000 hours of time are reviewed twice a year

Support for New and Established Users TeraGrid Advanced Support for Applications (ASTA): Request help with code optimization, workflow improvement and gateways through TeraGrid User Portal: Provides single location for information and help Science Gateways: User access without allocation request, simplifies access to resources - contact the Gateway project TeraGrid Pathways: New user support, mentoring, fellowships Campus Champions: Individuals at your institution to offer support HPC University: Online public resources More details on support resources to follow…

TeraGrid Web Resources TeraGrid User Portal for managing user allocations and job flow Knowledge Base for quick answers to technical questions User Information including documentation, information about hardware and software resources Science Highlights News and press releases Education, outreach and training events and resources In general, seminars and workshops will be accessible via video on the Web. Extensive documentation will also be Web-based.

What is a Science Gateway? A Science Gateway –Enables scientific communities of users with a common scientific goal –Uses high performance computing –Has a common interface –Leverages community investment Three common forms: –Web-based portals –Application programs running on users' machines but accessing services in TeraGrid –Coordinated access points enabling users to move seamlessly between TeraGrid and other grids

How can a Gateway help? Make science more productive –Researchers use same tools –Complex workflows –Common data formats –Data sharing Bring TeraGrid capabilities to the broad science community –Lots of disk space –Lots of compute resources –Powerful analysis capabilities –A nice interface to information

Gateway Highlight NanoHub Harnesses TeraGrid for Education Nanotechnology education Used in dozens of courses at many universities Teaching materials Collaboration space Research seminars Modeling tools Access to cutting edge research software
