i-pi tool
i-PI tool
-------------------
The tools/i-pi directory contains a version of the i-PI package, with
all the LAMMPS-unrelated files removed. It is provided so that it can
be used with the :doc:`fix ipi <fix_ipi>` command to perform
path-integral molecular dynamics (PIMD).
.. versionchanged:: TBD
The tools/i-pi directory used to contain a bundled version of the i-PI
software package for use with LAMMPS. This version, however, was
removed in 06/2024.
The i-PI package was created and is maintained by Michele Ceriotti,
michele.ceriotti at gmail.com, to interface to a variety of molecular
dynamics codes.
See the tools/i-pi/manual.pdf file for an overview of i-PI, and the
:doc:`fix ipi <fix_ipi>` page for further details on running PIMD
calculations with LAMMPS.
i-PI is now available via PyPi using the pip package manager at:
https://pypi.org/project/ipi/
Here are the commands to set up a virtual environment and install
i-PI into it with all its dependencies.
.. code-block:: sh
python -m venv ipienv
source ipienv/bin/activate
pip install --upgrade pip
pip install ipi
To install the development version from GitHub, please use:
.. code-block:: sh
pip install git+https://github.com/i-pi/i-pi.git
For further information, please consult the [i-PI home
page](https://ipi-code.org).

Obtaining i-PI
""""""""""""""
A simple version of the i-PI package, containing only files needed for use
with LAMMPS, is provided in the tools/i-pi directory. We recommend you
obtain the latest stable version from the github repository of i-PI,
or from the python package index.
Here are the commands to set up a virtual environment and install
i-PI into it with all its dependencies via the PyPi repository and
the pip package manager.

This folder used to contain a bundled version of [i-PI](https://ipi-code.org)
but the bundled version was removed in 06/2024.
i-PI is available via PyPi using the pip package manager at:
https://pypi.org/project/ipi/
Here are the commands to set up a virtual environment and
install i-PI into it with all its dependencies.
``` sh
python -m venv ipienv
source ipienv/bin/activate
pip install --upgrade pip
pip install ipi
```
For further information and other methods of installing i-PI,
please consult the [i-PI home page](https://ipi-code.org).

i-PI V1.0 -- LAMMPS
-------------------
A Python interface for ab initio path integral molecular dynamics simulations.
i-PI is composed of a Python server (i-pi itself, that does not need to be
compiled but only requires a relatively recent version of Python and Numpy)
that propagates the (path integral) dynamics of the nuclei, and of an external
code that acts as client and computes the electronic energy and forces.
This is typically a patched version of an electronic structure code, but a
simple self-contained Fortran driver that implements Lennard-Jones and
Silveira-Goldman potentials is included for test purposes.
This folder contains a stripped-down version to be used with LAMMPS, and might
not contain all the features of the latest version. Please see
[http://epfl-cosmo.github.io/gle4md/index.html?page=ipi] or
[http://github.com/i-pi/i-pi] to obtain an up-to-date version.
Quick Installation and Test
---------------------------
Follow these instruction to test i-PI. These assume to be run from a Linux
environment, with a recent version of Python, Numpy and gfortran, and that
the terminal is initially in the i-pi package directory (the directory
containing this file).
* Generate the driver code
::
$ cd driver
$ make
$ cd ..
* Run one of the examples
This will first start the wrapper in the background, redirecting the output on
a log file, then run a couple of instances of the driver code and then follow
the progress of the wrapper by monitoring the log file::
$ cd examples/tutorial/tutorial-1/
$ ../../../i-pi tutorial-1.xml > log &
$ ../../../drivers/driver.x -h localhost -p 31415 -m sg -o 15 &
$ ../../../drivers/driver.x -h localhost -p 31415 -m sg -o 15 &
$ tail -f log
The monitoring can be interrupted with ``CTRL+C`` when the run has finished (5000 steps)

-- Examples of i-PI working with LAMMPS --
-- Example with Tersoff graphene potential --
Uses the Tersoff parameters of Lindsay and Broido PRB 81, 205441 (2010)
to run a short simulation of graphene with the LAMMPS MD code.
-- Example with the q-TIP4P-F water potential --
* This gives an example of water with the q-TIP4P-F potential
of Scott Habershon, Thomas E. Markland and David E. Manolopoulos,
J. Chem. Phys., 131, 024501, (2009).
* State point: (N, V, T) = (216 water molecules, 43737 a_0**3, 298 K)
* This demonstrates the convergence of the kinetic and potential energy
using the ring polymer contraction (RPC) method of Thomas E. Markland and
David E. Manolopoulos, J. Chem. Phys. 129, 024105, (2008), and
the PIGLET method of Michele Ceriotti and
David Manolopoulos, Phys. Rev. Lett., 109, 100604, (2012).
** Run the examples automatically:
* First, it is necessary to patch and compile LAMMPS, and create a make.in
file containing the path to the executable and i-pi, e.g.
LAMMPS:=~/bin/lmp_serial
IPI:=~/bin/i-pi
* The runs can be done automatically using the Makefile provided. The make
targets are self-explanatory. To run the RPC example, for instance, just type:
$ make h2o-rpc
* To clean up output files:
$ make clean
** Run the examples manually:
* Go back to the example directory and run
$ python path/i-pi input.xml
the wrapper will start and sit waiting on the UDS /tmp/ipi.
* Open a separate terminal and run the LAMMPS driver code using:
$ path/lammps/src/lmp_serial < in.water
For the RPC run, instead use:
$ path/lammps/src/lmp_serial < in.water_longrange
$ path/lammps/src/lmp_serial < in.water_shortrange
You can run multiple instances of the code; it is so fast that parallel
scaling won't be appreciable.
* If your system does not support Unix domain sockets, just set in input.xml
<socket mode="unix"> <port> port_no </port>
To make the client socket connect, the in.water file should
be changed so that it has the line:
fix 1 all driver hostname port_no
where hostname is the address the socket is binding to; either graphene, piglet_2,
piglet_4, piglet_8, rpc_long, rpc_short or no_rpc depending on the run.
