Abstract
Molecular dynamics is widely used method of computational chemistry. With growing size of simulated systems and length of simulations, sequential analyzes of resulting trajectories become time demanding. Thus there is a need to speed up trajectory analyzes. Recently, we have designed, implemented and tested tools for fast analyzes of long molecular simulation trajectories. Our implementation uses parallel processing of trajectories with arbitrary number of processors focused on binding free energy calculations. Moreover this approach can be easily extended to other analyzes, e.g. radius of gyration, solute/solvent contacts, etc. Developed tools were applied on the calculation of binding free energies using MM/PBSA method. Two test cases were selected: a) LgtC galactosyltransferase from Niesseria meningitidis and b) lectin PA-IIL from Pseudomonas aeruginosa complexed. The 28-times acceleration on 32 processors was achieved, which shows 90 % parallel efficiency proving suitability of used approach.
