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. 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. 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. Adam Burrows, Princeton, SciDAC4-TEAMS collaboration 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. This is the largest and most comprehensive 3D study ever performed in supernova theory. 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. 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. The Core-collapse supernova problem is a long-standing multi-physics conundrum in radiation/hydrodynamics that has resisted solution for more than 50 years.
