Timothy Giese and Darrin York have published a new paper that reports a GPU-Accelerated Parameter Interpolation Thermodynamic Integration Free Energy Method in the Journal of Chemical Theory and Computation. The method has the practical advantage that no modification of the main MD code is required to propagate the dynamics, enabling all the performance benefits of GPU-acceleration to be realized, in addition to unlocking the full spectrum of features available within the MD software, such as Hamiltonian replica exchange (HREM).
