OpenMM
- OpenMM 4: A Reusable, Extensible, Hardware Independent Library for High Performance Molecular Simulation
- "Derivatives of the potential are not possible in this framework, so thermodynamic integration (TI) cannot be used".
- Alchemical free energy calculations in OpenMM - Describes thermodynamic integration (TI) and Bennett acceptance ratio (BAR) and explains why multistate BAR (MBAR) is better.
- Tinker-OpenMM: Absolute and relative alchemical free energies using AMOEBA on GPUs - 200x faster than a single GPU core.
