MISSION

In today's world, supercomputers are essential to addressing scientific topics
of national interest, including clean energy, new materials, climate change, the
origins of the universe, and the nature of matter. The SciDAC program was
initiated in 2001 (Program Plan) to develop the Scientific Computing Software
and Hardware Infrastructure needed to advance scientific discovery using
supercomputers. As supercomputers continuously evolve, direct engagement of
computer scientists and applied mathematicians with the scientists of targeted
application domains becomes ever more necessary for taking full advantage of
these new systems. In this regard, SciDAC is a partnership involving US
Department of Energy’s all 6 Office of Science (SC) programs — Advanced
Scientific Computing Research, Basic Energy Sciences, Biological and
Environmental Research, Fusion Energy Sciences, High-Energy Physics, and Nuclear
Physics — as well as Office of Nuclear Energy to dramatically accelerate
progress in scientific computing that delivers breakthrough scientific results
through partnerships composed of applied mathematicians, computer scientists,
and scientists from other disciplines.

Since its inception, the SciDAC model has accelerated the pace of scientific
discovery. Now in its fourth cycle, SciDAC continues to address mathematical and
computational challenges related to predictive modeling and high fidelity
simulations and to the generation and management of large data sets, increased
demand for scientific credibility, and expected disruptions in computer
architectures.

Although SciDAC is a partnership among SC programs, it is also built around
collaborative teams of experts from national laboratories, universities, and
other research organizations. This approach not only taps into the broadest
range of expertise but also ensures that the resulting tools and methods will be
available to the wider research community.

THREE-DIMENSIONAL SIMULATIONS OF CORE-COLLAPSE SUPERNOVA EXPLOSIONS

The Core-collapse supernova problem is a long-standing multi-physics conundrum
in radiation/hydrodynamics that has resisted solution for more than 50 years. We
are now in a position to simulate in three dimensions the detailed collapse and
explosive evolution of the cores of the progenitor massive stars.

Using the sophisticated code Fornax, developed expressly to address supernova
theory, we have recently simulated (using NERSC, Blue Waters, Stampede2) more
than ten 3D neutrino-radiation/hydrodynamics models (and this is a fraction of
our planned model suite, soon to be joined by INCITE/Theta runs), most of which
explode naturally with default physics. This is the largest and most
comprehensive 3D study ever performed in supernova theory.

Together with our exploration of the supernova mechanism, we are calculating the
recoil kicks, the gravitational wave signals, the debris morphologies, the
neutrino signatures, and the nucleosynthesis associated with these 3D models of
explosion.
