SUMMARY:MS6E - Ray Tracing for Scientific Applications
DESCRIPTION:Ray tracing is a highly accurate but computationally expensive
  technique for simulating the propagation of waves or particles in computa
 tional geometries. While widely employed in graphics rendering, this sympo
 sium explores adaptations of ray tracing for scientific applications. Pres
 enters will discuss domain-specific challenges, optimizations, and HPC con
 siderations within astrophysics, in-air acoustics, and particle transport 
 applications. Prof. Monika Mościbrodzka will discuss ray tracing for astro
 physical applications, with a focus on black hole imaging. Mr. Wouter Jans
 en will discuss acoustic ray tracing for simulating the echolocation behav
 ior of bats. Dr. Elliott Biondo will discuss GPU-accelerated ray tracing w
 ithin particle transport simulations for high-energy physics and nuclear e
 ngineering applications, including the use of tree-based acceleration stru
 ctures and geometry-specific tracking algorithms. The wide range of scient
 ific fields represented in this symposium will foster valuable cross-disci
 plinary collaborations and knowledge sharing among typically disparate res
 earch communities.\n\nRay Tracing for Scientific Applications Panel Discus
 sion\n\nThis panel discussion, featuring the three speakers, will provide 
 an opportunity for extended audience questions and deeper engagement with 
 the topics presented. It will also allow the speakers to interact with one
  another, compare methods, and discuss overlapping challenges across their
  fields.\n\n\nElliott Biondo (Oak Ridge National Laboratory)\n------------
 ---------\nRay Tracing Methods for GPU-Accelerated Particle Transport Simu
 lations\n\nMonte Carlo (MC) particle transport simulations are integral to
  (1) the high-energy physics event reconstruction process, and (2) estimat
 ing radiological quantities within nuclear reactors. This method involves 
 tracking individual particles through a computational geometry using a ran
 dom walk techni...\n\n\nElliott Biondo (Oak Ridge National Laboratory)\n--
 -------------------\nRay Tracing Applications in Imaging of Astrophysical 
 Black Holes\n\nI will discuss ray tracing for astrophysics applications, w
 ith a focus on black hole imaging. Astrophysical black holes, i.e., those 
 which astronomers do observe in a near and far Universe, are not always su
 rrounded by vacuum but are often embedded in extremely hot swirl of plasma
  rotating almost at...\n\n\nMonika Moscibrodzka (Radboud University)\n----
 -----------------\nSimulating Biological and Engineered In-Air Acoustic Sy
 stems Using Ray Tracing\n\nRay tracing offers powerful capabilities for si
 mulating wave propagation in diverse scientific fields, including acoustic
 s. This presentation focuses on its application to in-air acoustic simulat
 ions, furthering our understanding of biological echolocation (e.g., bats)
  and advancing the development ...\n\n\nWouter Jansen (University of Antwe
