Benchmarking with Supernovae: A Performance Study of the FLASH Code
Joshua Martin, Catherine Feldman, Eva Siegmann +7
Astrophysical simulations are computation, memory, and thus energy intensive, thereby requiring new hardware advances for progress. Stony Brook University recently expanded its com…
Challenges Modeling the Low-Luminosity Type Iax Supernovae
Catherine Feldman, Ellis Eisenberg, Dean M. Townsley +1
Numerical models allow the investigation of phenomena that cannot exist in a laboratory. Computational simulations are therefore essential for advancing our knowledge of astrophysi…
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…
Dimming the Lights: 2D Simulations of Deflagrations of Hybrid C/O/Ne White Dwarfs using FLASH
Catherine Feldman, Nathanael Gutierrez, Ellis Eisenberg +3
The dimmest and most numerous outlier of the Type Ia supernova population, Type Iax events, is increasingly being found in the results of observational campaigns. There is currentl…
A Further Study of Linux Kernel Hugepages on A64FX with FLASH, an Astrophysical Simulation Code
Catherine Feldman, Smeet Chheda, Alan C. Calder +4
We present an expanded study of the performance of FLASH when using Linux Kernel Hugepages on Ookami, an HPE Apollo 80 A64FX platform. FLASH is a multi-scale, multi-physics simulat…
On Using Linux Kernel Huge Pages with FLASH, an Astrophysical Simulation Code
Alan C. Calder, Catherine Feldman, Eva Siegmann +4
We present efforts at improving the performance of FLASH, a multi-scale, multi-physics simulation code principally for astrophysical applications, by using huge pages on Ookami, an…
