Recent Principal Investigator (PI) meeting • Was to be a grand kickoff meeting in Sep. • 9/11 derailed that • Held Jan 16/17 in Washington DC area • Chance for • Support and interest of Jim Decker • Foster collaboration – use ISICs, cross fertilization SciDAC Lattice All-Hands Meeting, Jlab
Challenges for HENP SciDAC • Extend our traditions of huge international collaborations for experimental science into Theory and Computational Science • work in multi-disciplinary teams, build community codes to deal with the size and complexity of the problems • apply innovative math and computing techniques and algorithms to problems • work effectively together (Collaborative Tools/Grid) • Strive for science deliverables soon and harness all the human and computing resources to meet the science goals SciDAC Lattice All-Hands Meeting, Jlab
Challenges for HENP SciDAC • Evolve the scientific codes to run on the multi-Teraflop computers of tomorrow • Portable, scalable codes that can use today’s resources for scientific discovery and be prepared for the next generation of computing resources • Well layered, structured and supported community-wide codes • Instrumented codes to optimize performance and understand the type of computers that will meet the needs in the most cost effective manner SciDAC Lattice All-Hands Meeting, Jlab
Presentations from 2 of the HENP SciDAC projects • Both have gone a long way in forming true multi-disciplinary collaborations with strong ties to applied mathematicians and computer scientists • Both have scientific goals with some short-term results expected, that they will tell you about • Shedding New Light on Exploding Stars: Terascale Simulations of Neutrino-Driven Supernovae and their Nucleosynthesis (Mezzacappa – PI) • Advanced Computing for 21st Century Accelerator Science and Technology (Ryne, Ko – PIs) SciDAC Lattice All-Hands Meeting, Jlab
