SUMMARY:Programmable Interactive Visualization of a Core-Collapse Supernov
 a Simulation
DESCRIPTION:Roland Haas (University of Illinois, National Center for Super
 computing Applications); Philipp Mösta (University of California, Berkeley
 ); and Mahendra Roopa, Alexander Kuhn, and Marc Nienhaus (Nvidia Corporati
 on)\n\nCore-collapse supernovae (CCSN) are the birth places of neutron sta
 rs and black holes. They liberate the ashes of stellar evolution, seeding 
 the interstellar gas with the elements from which planets form and life is
  made. Despite their importance for much of astrophysics, our understandin
 g of the supernova explosion mechanism and its dependence on progenitor st
 ar properties, is still incomplete. In addition, CCSN simulations generate
  terabytes of output posing additional challenges regarding the effective 
 analysis of the simulated physical processes. To address those challenges,
  we present Nvidia IndeX as a scalable framework to visualize the simulati
 on output. The framework features a streaming-based architecture to intera
 ctively explore simulation results in distributed multi-GPU environments. 
 We demonstrate how to customize specialized sampling programs for volume a
 nd surface rendering to cover specific analysis questions of CCSN simulati
 ons. This provides an extensive level of control over the visualization wh
 ile efficiently using available resources to achieve high-levels of perfor
 mance and visual accuracy.\n\nTag: Visualization\n\nRegistration Category:
