Computing nuclear response functions with time-dependent coupled-cluster theory
Francesca Bonaiti, Cody Balos, Kyle Godbey +3
We compute nuclear response functions by solving the time-dependent A-body Schrödinger equation, recording the time-dependent transition moment and extracting spectral information…
New Time Integrators and Capabilities in SUNDIALS Versions 6.2.0-7.4.0
Steven B. Roberts, Mustafa Ağgül, Daniel R. Reynolds +3
SUNDIALS is a well-established numerical library that provides robust and efficient time integrators and nonlinear solvers. This paper overviews several significant improvements an…
SUNDIALS Time Integrators for Exascale Applications with Many Independent ODE Systems
Cody J. Balos, Marc Day, Lucas Esclapez +8
Many complex systems can be accurately modeled as a set of coupled time-dependent partial differential equations (PDEs). However, solving such equations can be prohibitively expens…
Leveraging Mixed Precision in Exponential Time Integration Methods
Cody J. Balos, Steven Roberts, David J. Gardner
The machine learning explosion has created a prominent trend in modern computer hardware towards low precision floating-point operations. In response, there have been growing effor…
Data-driven time-scale separation of ODE right-hand sides using dynamic mode decomposition and time delay embedding
Cody J. Balos
Multi-physics simulation often involve multiple different scales. The ARKODE ODE solver package in the SUNDIALS library addresses multi-scale problems with a multi-rate time-integr…
Enabling GPU Accelerated Computing in the SUNDIALS Time Integration Library
Cody J. Balos, David J. Gardner, Carol S. Woodward +1
As part of the Exascale Computing Project (ECP), a recent focus of development efforts for the SUite of Nonlinear and DIfferential/ALgebraic equation Solvers (SUNDIALS) has been to…
Enabling New Flexibility in the SUNDIALS Suite of Nonlinear and Differential/Algebraic Equation Solvers
David J. Gardner, Daniel R. Reynolds, Carol S. Woodward +1
In recent years, the SUite of Nonlinear and DIfferential/ALgebraic equation Solvers (SUNDIALS) has been redesigned to better enable the use of application-specific and third-party…
SUNDIALS Multiphysics+MPIManyVector Performance Testing
Daniel R. Reynolds, David J. Gardner, Cody J. Balos +1
In this report we document performance test results on a SUNDIALS-based multiphysics demonstration application. We aim to assess the large-scale parallel performance of new capabil…
