This project contains the files needed to benchmark the AMOEBA force field as implemented in OpenMM and TINKER. The contents are:

1) OpenMM and TINKER input files for six water boxes of progressively increasing size (216 through 288,000 molecules) and DHFR in explicit water from the Joint AMBER-CHARMM benchmark.

2) Script for automatically running the benchmark across different methods (i.e. force field and run parameters), systems, and platforms.

3) Output data from running the benchmark on a high performance compute node (CPU: 2x Intel Xeon E5-2643 3.30GHz, GPU: NVidia GeForce GTX Titan Black).

4) Instruction manual.

The simulations are NVT (298.15 K), 1 and 2 fs time steps (2 fs time step uses MTS algorithm), PME electrostatics with real space cutoff 7.0 Angstrom, vdW cutoff 9.0 Angstrom. Simulation speed is given in ns/day.
