SOLAR Consortium: Accelerated Ray Tracing for Scientific Simulations
Parallel Programming Languages, Libraries, and Models
TimeWednesday, 18 November 202010am - 10:30am EDT
DescriptionMany physical simulations incorporate vector mathematics to model phenomena such as radiative transfer and to compute behavior such as particle advection. Hardware-optimized ray tracing engines, tuned by processor manufacturer engineers, can accelerate simulation critical sections that depend on ray-based traversals and intersections. This Exhibitors Forum will serve as a venue for developers and users of simulations, visual analysis codes, and ray tracers to discuss interfaces, capabilities, and performance. This meeting will continue the conversation toward standardization of ray tracer interfaces to facilitate their expanding role throughout scientific workflows, including data evaluation, insight formulation, discovery communication, and presentation-quality artifact generation.
This Exhibitors Forum aims to build awareness and develop community for using hardware-optimized ray tracing engines in simulation codes that make extensive use of ray-like vector calculations, such as computing radiative transfer with Monte Carlo methods or advecting particles through a vector field, building on the Khronos ANARI analytic ray tracing standard. Using hardware-tuned methods for traversal and intersection in the inner loops of such simulations can provide significant performance enhancement, particularly on next-generation GPU hardware with dedicated ray processing logic. Hardware-tuned ray tracers, however, have not yet been widely adopted due to the graphics-centric nature of their interfaces and terminology. This Forum seeks to build community among simulation users and developers, visualization developers, and ray tracing engine developers in order to standardize interfaces for ray tracer use for simulation and for coprocessing of simulation and analysis.
