Efficient Data Management in Neutron Scattering Data Reduction Workflows at ORNL
William F Godoy, Peter F Peterson, Steven E Hahn +1
Oak Ridge National Laboratory (ORNL) experimental neutron science facilities produce 1.2\,TB a day of raw event-based data that is stored using the standard metadata-rich NeXus sch…
Applying Distributed Ledgers to Manage Workflow Provenance
Jay Jay Billings
Sharing provenance across workflow management systems automatically is not currently possible, but the value of such a capability is high since it could greatly reduce the amount o…
Will humans even write code in 2040 and what would that mean for extreme heterogeneity in computing?
Jay Jay Billings, Alexander J. McCaskey, Geoffroy Vallee +1
Programming trends suggest that software development will undergo a radical change in the future: the combination of machine learning, artificial intelligence, natural language pro…
Toward Common Components for Open Workflow Systems
Jay Jay Billings, Shantenu Jha
The role of scalable high-performance workflows and flexible workflow management systems that can support multiple simulations will continue to increase in importance. For example,…
The Eclipse Integrated Computational Environment
Jay Jay Billings, Andrew R. Bennett, Jordan Deyton +10
Problems in modeling and simulation require significantly different workflow management technologies than standard grid-based workflow management systems. Computational scientists…
Explicit Integration with GPU Acceleration for Large Kinetic Networks
Benjamin Brock, Andrew Belt, Jay Jay Billings +1
We demonstrate the first implementation of recently-developed fast explicit kinetic integration algorithms on modern graphics processing unit (GPU) accelerators. Taking as a generi…
A domain-specific analysis system for examining nuclear reactor simulation data for light-water and sodium-cooled fast reactors
Jay Jay Billings, Jordan H. Deyton, S. Forest Hull +2
Building a new generation of fission reactors in the United States presents many technical and regulatory challenges. One important challenge is the need to share and present resul…
An Integrated Programming and Development Environment for Adiabatic Quantum Optimization
Travis S. Humble, Alex J. McCaskey, Ryan S. Bennink +5
Adiabatic quantum computing is a promising route to the computational power afforded by quantum information processing. The recent availability of adiabatic hardware has raised cha…
Explicit Integration of Extremely-Stiff Reaction Networks: Partial Equilibrium Methods
M. W. Guidry, J. J. Billings, W. R. Hix
In two preceding papers we have shown that, when reaction networks are well-removed from equilibrium, explicit asymptotic and quasi-steady-state approximations can give algebraical…
Explicit Integration of Extremely-Stiff Reaction Networks: Asymptotic Methods
M. W. Guidry, R. Budiardja, E. Feger +6
We show that, even for extremely stiff systems, explicit integration may compete in both accuracy and speed with implicit methods if algebraic methods are used to stabilize the num…
