Improving Performance, Reducing Technical Debt, and Unlocking Future Enhancement of the Velodyne Hydro-Structural Solver using ASCR Funded Libraries

The Department of Energy has invested in the research and development of advanced computational analysis libraries, which can be used to build advanced computational physics tools that scale on modern high performance computing architectures. To be sustainably maintained and for the public to receive a return on this investment, these libraries must be implemented in software products across a variety of industries. In order to address the problem, the Department of Energy advanced computational analysis libraries will be implemented into an advanced, massively-parallel, multi-physics, hydro-structural solver. This will improve the maintainability and performance of the hydro-structural solver, with some improvements also being upstreamed back into the Department of Energy’s libraries when there is a benefit to the public in doing so. The approach will be a collaborative development effort with the Department of Energy with technical developments being sought by both parties. A collaborative research and development effort will be executed to develop a robust and flexible saddle point and/or block matrix solver package. The Department of Energy will provide technical expertise in their libraries and development effort to support integration (e.g. Application Program Interfaces, etc.). The proposer will work on the implementation of the solver package and provide benchmarking data and upstream changes to the Department of Energy libraries. The product of this effort at the conclusion of the Phase I will be a hierarchically structured solver that can be leveraged for a range of applications and the means for the Department of Energy libraries to interface with such a package in other products for public benefit. The adoption and implementation of advanced Department of Energy libraries into a variety of software products, along with the benchmarking data that comes with doing so, will allow these libraries to be refined and made easier to integrate in future applications. The application of these libraries in industry will provide a competitive advantage to American companies against global competitors in many domains such as defense, oil and gas, automotive, and aerospace.
