What is `GPUMD`?

GPUMD stands for Graphics Processing Units Molecular Dynamics.
GPUMD is a highly efficient general-purpose molecular dynamics (MD) package fully implemented on graphics processing units (GPUs).
GPUMD enables training and using a class of machine-learned potentials (MLPs) called neuroevolution potentials (NEPs). See this nep-data Gitlab repo for some of the published NEP potentials and the related training/testing data.

Prerequisites

You need to have a GPU card with compute capability no less than 3.5 and a CUDA toolkit no older than CUDA 9.0.
Works for both Linux (with GCC) and Windows (with MSVC) operating systems.

Compile GPUMD

Go to the src directory and type make.
When the compilation finishes, two executables, gpumd and nep, will be generated in the src directory.

Run GPUMD

Go to the directory of an example and type one of the following commands:
- path/to/gpumd
- path/to/nep

Colab tutorial

We provide a Colab Tutorial to show the workflow of the construction of a NEP model and its application in large-scale atomistic simulations for PbTe system. This will run entirely on Google's cloud virtual machine.
You can also check other offline tutorials in the examples.

Manual

For users and developers:
- Latest released version: https://gpumd.org/
- Development version: https://gpumd.org/dev/
For developers only:

Tools

Various tools for GPUMD and NEP can be found in tools.

CPU version of NEP

There is a standalone C++ implementation of the neuroevolution potential (NEP) in the NEP_CPU repository, which serves as the engine for many Python packages and provides an interface to the LAMMPS package.
