Conference Keynotes

“Importance of Cyberinfrastructure for Numerical Relativity”
Dr. Gabrielle Allen Louisiana State University
Tuesday August 3rd, 9:00 am
Accurately modeling astrophysical systems that are governed by Einstein's Equations of General Relativity, such as black hole, stellar core collapse, or gamma ray bursts, require the use of cutting edge computational resources and software. In this talk, Dr. Allen will describe how numerical relativity has motivated and led to the development of the Cactus Framework - an open, collaborative component framework and set of toolkits for scientific computing, as well as numerous advanced scenarios exploiting Grid and distributed computing, high speed networks, and advanced visualization. She will describe how this work has led to a new software effort in numerical relativity, the Einstein Toolkit Consortium, which is developing and supporting the software for state-of-the-art simulations involving general relativistic “magnetohydrodynamics” and working toward a sustainable model for software development. Finally, Dr. Allen will discuss the importance of the TeraGrid and prior national resources in supporting these and reflect on current and future needs in scientific computing infrastructure.

 

“The Essential Role Cyberinfrastructure Plays in the Geosciences Portfolio”
Dr. Tim Killeen National Science Foundation Geosciences Directorate
Wednesday August 4th, 8:45 am
The NSF Geosciences Directorate has long supported the development of sustained cyberinfrastructure. These investments have significantly increased the capabilities and productivity of the national geosciences community. Complementary investments made by other directorates and offices within NSF, and by other agencies, have enhanced and leveraged the GEO-funded programs. As a result, a rich portfolio of cyberinfrastructure tools and capabilities, together with an experienced and knowledgeable community has resulted. The Geosciences community has worked with systems that encompass, for example, workstations to supercomputers, smart sensors to global remote sensor networks, and sophisticated data systems available to large communities of users. Also, programs to develop human capital have been emphasized, ranging from graduate student educational programs to post-docs cyberinfrastructure programs and support for technology leaders for the entire science community. On the horizon is yet another round of investments that will provide the geosciences community with an ever expanding range of capabilities for discovery. Dr. Killeen will present a brief review of the geosciences investments in cyberinfrastructure and some of the significant outcomes and future plans.
 
"Challenges in Preparing Applications for Blue Waters"
Dr. Bob Wilhelmson National Center for Supercomputing Applications
Thursday August 5th, 9:15 am
Blue Waters is expected to be the most powerful supercomputer in the world for open scientific research when it comes online in 2011. The system is a joint effort between NCSA, the University of Illinois, IBM, and the National Science foundation. It will be the first system of its kind to sustain one petaflop performance on a range of science and engineering applications. The project includes provision of the computer system and intense collaboration with dozens of teams in the development of science and engineering applications. This collaboration will help ensure that scientists and engineers across the country will be able to use Blue Waters to its fullest potential. Dr. Wilhelmson will provide a brief overview of the Blue Waters project and focus on some of the applications that are being prepared for use on the system when it becomes available.
