GPUMD
stands for Graphics Processing Units Molecular Dynamics. It is a general-purpose molecular dynamics (MD) code fully implemented on graphics processing units (GPUs).- Force evaluation for many-body potentials has been significantly accelerated by using GPUs [1], thanks to a set of simple expressions for force, virial stress, and heat current derived in Refs. [2, 3].
- Apart from being highly efficient, another unique feature of GPUMD is that it has useful utilities to study heat transport [2, 3, 4, 5].
- It can run MD simulations with the machine-learning based force constant potential (FCP) [6].
- It can train the NEP machine-learning potential [7, 8] and run MD simulations with it. See this nep-data Gitlab repo for all the published NEP potentials and the related training/testing data.
- You need to have a GPU card with compute capability no less than 3.5 and a
CUDA
toolkit no older thanCUDA
9.0. - Works for both Linux (with GCC) and Windows (with MSVC) operating systems.
- Go to the
src
directory and typemake
. When the compilation finishes, two executables,gpumd
andnep
, will be generated in thesrc
directory.
- See the
examples/readme.md
file.

- One of the developers, Alexander J. Gabourie, has written a Python package for pre-processing and post-processing data related to
GPUMD
. Here is the link: https://github.com/AlexGabourie/thermo
- Before the first release, GPUMD was developed by Zheyong Fan, with help from Ville Vierimaa (Previously Aalto University) and Mikko Ervasti (Previously Aalto University) and supervision from Ari Harju (Previously Aalto University).
