SUMMARY:Programmable Interactive Visualization of a Core-Collapse Supernov
 a Simulation
DESCRIPTION:Scientific Visualization & Data Analytics Showcase\nVisualizat
 ion, Tech Program Reg Pass\n\nProgrammable Interactive Visualization of a 
 Core-Collapse Supernova Simulation\n\nHaas, Mösta, Roopa, Kuhn, Nienhaus\n
 \nCore-collapse supernovae (CCSN) are the birth places of neutron stars an
 d black holes. They liberate the ashes of stellar evolution, seeding the i
 nterstellar gas with the elements from which planets form and life is made
 . Despite their importance for much of astrophysics, our understanding of 
 the supernova explosion mechanism and its dependence on progenitor star pr
 operties, is still incomplete. In addition, CCSN simulations generate tera
 bytes of output posing additional challenges regarding the effective analy
 sis of the simulated physical processes. To address those challenges, we p
 resent Nvidia IndeX as a scalable framework to visualize the simulation ou
 tput. The framework features a streaming-based architecture to interactive
 ly explore simulation results in distributed multi-GPU environments. We de
 monstrate how to customize specialized sampling programs for volume and su
 rface rendering to cover specific analysis questions of CCSN simulations. 
 This provides an extensive level of control over the visualization while e
 fficiently using available resources to achieve high-levels of performance
  and visual accuracy.
