RPMDrate depends on several other packages in order to provide its full functional capabilities. The following dependencies are required to compile and run RPMD:
- Python (version 2.5.x or later, including any version of Python 3, is recommended)
- NumPy (version 1.5.0 or later is recommended)
- FFTW (version 3.3 or later is recommended)
- A standard Fortran 90/95 compiler (e.g.
gfortran,g95,ifort, etc.)
RPMDrate uses the f2py tool (bundled with NumPy) to expose its Fortran code
to Python.
The best way to obtain a copy of the repository is to clone it using git:
$ git clone git://github.com/GreenGroup/RPMDrate.git
This enables you to easy update your local clone with the latest changes. If you intend to contribute, you should fork the project on GitHub first, and clone from your fork.
RPMDrate is installed by invoking the setup.py script:
$ python setup.py install
This will compile the Fortran source and Python wrapper code, which may take some time. Note that you may need administrator privileges to install RPMD.
If you wish to use RPMDrate without installing, simply add the folder containing
this file to your PYTHONPATH environment variable and compile the source
code in-place using the command
$ python setup.py build_ext --inplace
A Makefile that wraps these commands has been provided. The Makefile also provides a clean target for deleting all files created during compilation.
RPMDrate comes with a large suite of unit tests that ensure functionality is working as intended. To run these tests, first install RPMDrate or compile it from source in-place using the directions above. Then, simply invoke the entire suite of unit tests using
$ python setup.py test
This will run all of the unit tests in sequence, which may take some time. If one or more unit tests fail, please report them on the GitHub issue tracker (if they aren't already reported).
