# Introduction

This repository contains the development version of the
[Purdue Reactive Molecular Dynamics](https://www.cs.purdue.edu/puremd) (PuReMD) project.

# Build Instructions

## Developer

To build, the following versions of software are required:

- git
- Autoconf v2.69+
- Automake v1.15+
- OpenMP v4.0+ compliant compiler (OpenMP versions only)
- MPI v2+ compliant library (MPI versions only)
- CUDA v6.0+ (CUDA versions only)

Instructions:
```bash
	git clone https://gitlab.msu.edu/SParTA/PuReMD.git
	cd PuReMD
	git submodule init
	git submodule update
	autoreconf -ivf
	./configure
	make
```

To build tarball releases after configuring a specific build target, run the following:

```bash
	make dist
```

## User

```bash
	# Download release tarball
	tar -xvf puremd-1.0.tar.gz
	cd puremd-1.0
	./configure
	make
```

By default, the shared memory version with OpenMP support will be built. For other build targets,
run ./configure --help and consult the documentation. An example of building the MPI+CUDA version
is given below.

```bash
	./configure --enable-openmp=no --enable-mpi-gpu=yes
```
