GPU offload on the tested system yields 4-12x throughput and up to 15x energy-efficiency gains over CPU-only execution for gromacs, lammps, OpenGadget3, AthenaK and dealii-X, with gains sensitive to problem granularity.
GPU version of OpenGadget3 matches CPU results across multiple test suites with chip-to-chip speedups of 2-5x.
