SUMMARY:GPU-Accelerated Neutrino Transport Solver for Multi-Dimensional Co
 re-Collapse Supernovae
DESCRIPTION:Minisymposium\nComputer Science and Applied Mathematics, Physi
 cs\n\nGPU-Accelerated Neutrino Transport Solver for Multi-Dimensional Core
 -Collapse Supernovae\n\nPan\n\nSelf-consistent core-collapse supernova sim
 ulations require lots of input physics to explore the explosion mechanism 
 and to predict the multi-messenger signals for future observations, includ
 ing multi-dimensional hydrodynamics, neutrino radiation transport, microph
 ysics, and general relativity.  Among these ingredients, neutrino tra
 nsport often dominates the computation and therefore become our first targ
 et to explore GPU acceleration. We have enabled OpenACC to accelerate our 
 neutrino transport solver with the Isotropic Diffusion Source Approximatio
 n (IDSA) in the publicly available hydrodynamics code, FLASH. We demonstra
 te that IDSA is an efficient scheme to explore core-collapse supernova sim
 ulations in multi-dimensions.
