D-Wave quantum annealer exploration

#

• Explored the D-Wave quantum annealer by bridging discrete and continuous optimization: sphere packing with local topological constraints and unequal volumes using a quadratic non-convex optimization specification

Multiphysics Eulerian code modernization

#

• Developed higher order function mappings over physics kernels in order to replace core mesh iteration patterns in multiphysics Eulerian codes

Accelerated asynchronous message passing interface (MPI) facility

#

• Unified cell-based adaptive mesh refinement (AMR) and $N$-body particle models and simulations using projective geometry and hashing: prototyped an accelerated asynchronous MPI facility

Radiation-Hydrodynamics codes at exascale

#

• Researched, designed, and implemented hash-based algorithms to discretize continuous spaces into computational meshes across scalable heterogeneous architectures with primary application in radiation/hydrodynamics codes for exascale machines

Shallow water equations model simulation using cell-based AMR on GPUs
