Implement and validate explicit solvent all-atom classical molecular dynamics running entirely on CUDA-enabled GPUs within the AMBER program package.
Implemented particle mesh Ewald (PME) electrostatics and standard statistical mechanical ensembles (NVE, NVT, and NPT) entirely on CUDA-enabled NVIDIA graphics processing units.
Evaluated three distinct precision algorithms (SPDP, SPFP, and DPDP) against conventional CPU-based AMBER implementations.
GPU-accelerated simulations achieved trajectory accuracy statistically indistinguishable from traditional CPU implementations while exceeding the performance of conventional CPU clusters and supercomputers.
Validation testing justified deprecating the pure single-precision (SPSP) engine in favor of hybrid and double-precision formulations.
