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…

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…
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…
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…
