Ookami: An A64FX Computing Resource
A. C. Calder, E. Siegmann, C. Feldman +8
We present a look at Ookami, a project providing community access to a testbed supercomputer with the ARM-based A64FX processors developed by a collaboration between RIKEN and Fuji…
Performance of an Astrophysical Radiation Hydrodynamics Code under Scalable Vector Extension Optimization
Dennis C. Smolarski, F. Douglas Swesty, Alan C. Calder
We present results of a performance study of an astrophysical radiation hydrodynamics code, V2D, on the Arm-based A64FX processor developed by Fujitsu. The code solves sparse linea…
Quantification of Incertitude in Black Box Simulation Codes
Alan C. Calder, Melissa M. Hoffman, Donald E. Willcox +3
We present early results from a study addressing the question of how one treats the propagation of incertitude, that is, epistemic uncertainty, in input parameters in astrophysical…
White Dwarf Mergers on Adaptive Meshes I. Methodology and Code Verification
Max P. Katz, Michael Zingale, Alan C. Calder +3
The Type Ia supernova progenitor problem is one of the most perplexing and exciting problems in astrophysics, requiring detailed numerical modeling to complement observations of th…
A Numerical Algorithm for Modeling Multigroup Neutrino-Radiation Hydrodynamics in Two Spatial Dimensions
F. Douglas Swesty, Eric S. Myra
It is now generally agreed that multidimensional, multigroup, radiation hydrodynamics is an indispensable element of any realistic model of stellar-core collapse, core-collapse sup…
Multigroup Models of the Convective Epoch in Core Collapse Supernovae
F. Douglas Swesty, Eric S. Myra
Understanding the explosion mechanism of core collapse supernovae is a problem that has plagued nuclear astrophysicists since the first computational models of this phenomenon were…
