Reduced Precision Diffusion Synthetic Acceleration for S Neutron Transport in LLNL's ARDRA using Hypre
Joanna Piper Morgan, Mario Ivan Ortega
Fast solution times in production discrete ordinates transport codes often require the use of diffusion synthetic acceleration (DSA). A good implementation of DSA will substantiall…
Hybrid Delta Tracking Schemes Using a Track-Length Estimator
Joanna Piper Morgan, Ilham Variansyah, Kayla B. Clements +2
In Monte Carlo radiation transport calculations, Woodcock-delta tracking is a common alternative to the more popular surface tracking technique. In this work we introduce a delta-t…
Comparing the Performance of MC/DC's on-GPU Event-based Processing Methods in Multigroup and Continuous-energy Problems
Braxton Cuneo, Joanna Piper Morgan, Ilham Variansyah +1
Monte Carlo / Dynamic Code (MC/DC) is a portable Monte Carlo neutron transport package for rapid numerical methods exploration in heterogeneous and HPC contexts, developed under th…
One-Cell Inversion for Solving Higher-Order Time-Dependent Radiation Transport on GPUs
Joanna Piper Morgan, Ilham Variansyah, Todd S. Palmer +1
To find deterministic solutions to the transient discrete-ordinates neutron-transport equation, source iterations (SI) are typically used to lag the scattering (and fission) source…
Enabling GPU Portability into the Numba-JITed Monte Carlo Particle Transport Code MC/DC
Joanna Piper Morgan, Braxton Cuneo, Ilham Variansyah +1
The Center for Exascale Monte Carlo Neutron Transport is developing Monte Carlo / Dynamic Code (MC/DC) as a portable Monte Carlo neutron transport package for rapid numerical metho…
Performance Portable Monte Carlo Neutron Transport in MCDC via Numba
Joanna Piper Morgan, Ilham Variansyah, Braxton Cuneo +2
Finding a software engineering approach that allows for portability, rapid development, and open collaboration for high-performance computing on GPUs and CPUs is a challenge. We im…
The Monte Carlo Computational Summit -- October 25 & 26, 2023 -- Notre Dame, Indiana, USA
Joanna Piper Morgan, Alexander Mote, Samuel Lee Pasmann +4
The Monte Carlo Computational Summit was held on the campus of the University of Notre Dame in South Bend, Indiana, USA on 25--26 October 2023. The goals of the summit were to disc…
Hybrid-Delta Tracking on a Structured Mesh in MCATK
J. P. Morgan, Travis J. Trahan, Timothy P. Burke +2
Monte Carlo Application Toolkit (MCATK) commonly uses surface tracking on a structured mesh to compute scalar fluxes. In this mode, higher fidelity requires more mesh cells and iso…
Development of MC/DC: a performant, scalable, and portable Python-based Monte Carlo neutron transport code
Ilham Variansyah, J. P. Morgan, Jordan Northrop +2
We discuss the current development of MC/DC (Monte Carlo Dynamic Code). MC/DC is primarily designed to serve as an exploratory Python-based MC transport code. However, it seeks to…
Exploring One-Cell Inversion Method for Transient Transport on GPU
J. P. Morgan, Ilham Variansyah, Todd S. Palmer +1
To find deterministic solutions to the transient neutron transport equation, iterative schemes are typically used to treat the scattering (and fission) source terms. We explo…
