Research Statement

My research area is the study of novel computational algorithms for the numerical solution of partial differential equations (p.d.e.s). The approach I've has taken in this research has been to derive numerical methods and develop software on both serial and parallel computers for a broad, mathematically-defined problem class in which the equations are decoupled in space and time. This has made it possible for users from different physical applications areas to solve their problems by creating a mathematical model which fits inside the general problem class.

  • PASC 2022 Conference - Best paper presentation Porting Uintah to Heterogeneous Systems The Uintah Computational Framework is being prepared to make portable use of forthcoming exascale systems, initially the DOE Aurora system through the Aurora Early Science Program. This paper describes the evolution of Uintah to be ready for such architectures. A key part of this preparation has been the adoption of the Kokkos performance portability layer in Uintah. The sheer size of the Uintah codebase has made it imperative to have a representative benchmark. The design of this benchmark and the use of Kokkos within it is discussed. This paper extends recent work with new scaling studies run 24x further than earlier studies. Results are shown for two benchmarks executing workloads representative of typical Uintah applications. These results demonstrate single-source portability across the DOE Summit and NSF Frontera systems with good strong-scaling characteristics. The challenge of extending this approach to anticipated exascale systems is also considered.

  • PASC 2019 Invited Minisymposium Talk Asynchronous AMR and Runtime Systems he uintah software has adopted an asynchronous task based approach since 2011 or so. Both traditional and amr for globally connected radiation problems are supported. In this work the advantages and challenges of an asynchronous approach are considered. The outcome of this is that a combination of asynchronous approaches with over decomposition allows scalability. Finally, we consider how to extend this approach to many different architectures using performance portability libraries for present and future leading edge architectures.

  • We present selected applications of scalable adaptive mesh refinement (AMR). The focus is on new algorithms for important features and functionalities and on latest science applications that rely on such features. Even though several algorithmic approaches to AMR are widely and successfully used for the numerical solution of partial differential equations, it remains challenging to incorporate complex physics, multiple scales, and non-element-based methods, as well as other sources of non-locality and non-uniformity. In this minisymposion, we highlight how such generalizations impact performance and scalability. We discuss the particular requirements on algorithm and application design at the largest scale, how low- and high-level simulation layers depend on each other, and how synergy can be maximized.

  • Algorithm xxxx: HiPPIS A High-Order Positivity-Preserving Mapping Software for Structured Meshes. Polynomial interpolation is an important component of many computational problems. In several of these computational problems, failure to preserve positivity when using polynomials to approximate or map data values between meshes can lead to negative unphysical quantities. Currently, most polynomial-based methods for enforcing positivity are based on splines and polynomial rescaling. The spline-based approaches build interpolants that are positive over the intervals in which they are defined and may require solving a minimization problem and/or system of equations. The linear polynomial rescaling methods allow for high-degree polynomials but enforce positivity only at limited locations (e.g., quadrature nodes). This work introduces open-source software (HiPPIS) for high-order data-bounded interpolation (DBI) and positivity-preserving interpolation (PPI) that addresses the limitations of both the spline and polynomial rescaling methods. HiPPIS is suitable for approximating and mapping physical quantities such as mass, density, and concentration between meshes while preserving positivity. This work provides Fortran and Matlab implementations of the DBI and PPI methods, presents an analysis of the mapping error in the context of PDEs, and uses several 1D and 2D numerical examples to demonstrate the benefits and limitations of HiPPI.
