D-Wave adiabatic quantum computer exploration

#

• Bridged discrete and continuous (quadratic, non-convex) optimization: sphere packing with local topological constraints and unequal volumes

Multiphysics (Eulerian) code modernization

#

• Developed higher order function mappings over physics kernels (replaced core mesh iteration patterns)

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

Radiation-Hydrodynamics codes at exascale

#

• Researched hash-based algorithms to discretize continuous spaces into computational meshes and tested on heterogeneous GPU clusters

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