A. SYSTEM REQUIREMENTS


To install and run the KIM API package you need the following:

1. A Unix/Linux/macOS system.

2. CMake (3.10 or later).

3. GNU compilers (gcc, g++, gfortran) version 4.8.x or higher or the
   corresponding Intel compilers, version 11.1 or higher.  Other compilers may
   also work.

4. wget or curl, sed, grep, tar, uname, etc. (used by the
   kim-api-collections-management utility).

5. Doxygen and Graphviz (for generating the documentation).

6. The bash-completion package (for facilitating command-line usage of the
   helper utilities).

7. pkg-config can be used by code needing to link against the kim-api library.


-------------------------------------------------------------------------------

B. QUICK START: For those who don't like to read and are a bit audacious.

Try the following:

   $ mkdir build && cd build
   $ cmake .. -DCMAKE_BUILD_TYPE=Release
   $ make
   $ sudo make install
   $ sudo ldconfig

For more information, see section D.

-------------------------------------------------------------------------------

C. PACKAGE LAYOUT AND OPERATION OVERVIEW


The KIM API package is a system-level library that aims to give computer
programmers the ability to write atomistic or molecular simulation programs
(Simulators) that can seamlessly interface with implementations of interatomic
potentials (Portable Models, PMs), regardless of the programming language in
which the codes are written.  The KIM API package provides a dedicated Portable
Model Interface (PMI) for use by simulators and PMs and referred to as the KIM
API/PMI.  A PM can include code and parameters all in one.  Or, a PM can
include just parameters and use a separate Model Driver (MD) library containing
the code.  There are also Simulator Models (SMs) that only work with a specific
simulator.  The KIM API package provides a dedicated Simulator Model Interface
(SMI) for use by simulators and SMs and referred to as the KIM API/SMI.  In
addition to the main KIM API library, a small number of associated helper
utilities are provided.

C.1. KIM API Library

The KIM API library provides the necessary routines for a Simulator to interact
with a PM or SM.  It also contains an interface for discovering what MDs, PMs,
and SMs are available in the KIM API Collections.  MDs, PMs, and SMs are built
and linked against the KIM API library, then installed in one of the
collections (see below) so that they are available for use with a simulator.
Simulators are built and linked against the KIM API library so that they can
access and use any of the available PMs and/or SM in the various collections.

C.2 COLLECTIONS FOR MODEL DRIVERS (MDs), PORTABLE MODELS (PMs), AND
    SIMULATOR MODELS (SMs)

The KIM API supports four Collections of Items.  These are the
"system-collection", the "user-collection", the
"environment-variable-collection", and the "CWD-collection" as described below.
Each collection consists of separate sets of three Item Types: MDs, PMs, and
SMs.  When the KIM API needs to use a particular MD, PD, or SM, it looks for
the item by type and name, first in the CWD-collection, then in the
environment-variable-collection, then in the user-collection, and finally in
the system-collection.  It uses the first match that it finds.  Note, it is
possible for a PM and its associated MD to be located in different collections.
The search for each is a separate and independent procedure.

See also the documentation for the Collections Interface (c++:
KIM::Collections; c: KIM_Collections; and Fortran: kim_collections_module).

C.2.1 THE SYSTEM-COLLECTION

The system-collection is a collection of MDs, PMs, and SMs that are available
to all simulators that use the KIM API library.  By default, this collection is
located in the same subdirectory as the KIM API library.  (See also the
"KIM_API_SYSTEM_*_DIR" build options in section D.2.4, below.)

MDs, PMs, and SMs may be built and installed to the system-collection at
anytime after the KIM API has been built and installed.

C.2.2 THE USER-COLLECTION

The user-collection is a collection of MDs, PMs, and SMs that are available
only to the user who owns the process for the simulator that uses the KIM API
library.  This collection is located in subdirectories that are specified by a
configuration file.  The user-collection may be populated with MDs, PMs, and
SMs after the KIM API has been built and installed.

The configuration file is named "${HOME}/.kim-api/<kim-api-uid>/config" by
default, where <kim-api-uid> is a unique identifier for the particular
installation of the kim-api being used (this allows multiple, independent,
installations on a single machine).  Here "${HOME}" is the user's home
directory.  (See item D below for build options controlling this default file
name.)  If the "KIM_API_CONFIGURATION_FILE" environment variable is set, its
value (interpreted as an absolute file name) will supersede the default
location and name of the configuration file.  For example, the following
commands will instruct the KIM API library to use a file named "kim-config" in
the /my-kim-stuff folder

   $ export KIM_API_CONFIGURATION_FILE=/my-kim-stuff/kim-config

If the configuration file does not exist, the KIM API library will create it
with a default configuration specifying that the user-collection files are
stored in "${HOME}/.kim-api/<kim-api-uid>/model-drivers/",
"${HOME}/.kim-api/<kim-api-uid>/portable-models/", and
"${HOME}/.kim-api/<kim-api-uid>/simulator-models/".  More generally, the values
in the configuration file may contain colon ':' (on Windows: semi-colon ';')
separated lists of fully-qualified directory names (starting, strictly, with
'/', '~/' or a root drive letter like 'C:/').  (See item D below for build
options controlling these defaults.)

C.2.3 THE ENVIRONMENT-VARIABLE-COLLECTION

The environment-variable-collection is a collection of MDs, PMs, and SMs that
are specified by the run-time environment of the process for the simulator that
uses the KIM API library.  The locations of this collection are specified by
the environment variables "KIM_API_MODEL_DRIVERS_DIR",
"KIM_API_PORTABLE_MODELS_DIR", and "KIM_API_SIMULATOR_MODELS_DIR".  These
variables should contain colon ':' (on Windows: semi-colon ';') separated lists
of absolute directory names where the collection MDs, PMs, and SMs, respectively,
are located.  (For example, in bash you could execute the command

   $ export KIM_API_PORTABLE_MODELS_DIR=/my-kim-stuff/models-i-am-developing:/my-kim-stuff/misc-portable-models

to have the KIM API look for PMs in /my-kim-stuff/models-i-am-developing first
and then look in /my-kim-stuff/misc-portable-models.  (Similarly for MDs and
SMs.)  The environment-variable-collection may be populated with MDs, PMs, and
SMs after the KIM API has been built and installed.

C.2.4 THE CWD-COLLECTION

The CWD-collection is a collection of MDs, PMs, SMs that are available to a
simulator at run-time.  The collection is located in the simulator process's
current working directory (CWD).  The CWD-collection may be populated with MDs,
PMs, and SMs after the KIM API has been built and installed.

C.3 HELPER UTILITIES

The KIM API package also includes a utility for managing the MDs, PMs, and SMs
contained in the various collections and for managing the configuration file.
This utility is called "kim-api-collections-management".  The KIM API package
installs bash completion scripts that are designed to work with the
"bash-completion" package (https://github.com/scop/bash-completion).  When
"bash-completion" is installed and activated on the system, tab-completions for
the collections management utility should be automatically loaded and available
for use.

In addition, when the KIM API package is installed to a "Local (non-global)"
(see D below) directory, the package also installs the "kim-api-activate" and
"kim-api-deactivate" scripts.  The activate script adds the utilities to the
executable PATH, adds the KIM API library to the PKG_CONFIG_PATH so that the
pkg-config utility can find it, and loads bash tab-completion support for the
collections management utility.  The deactivate script removes what the
activate script added.


-------------------------------------------------------------------------------

D. KIM API INSTALLATION

D.1 Typical Build Scenario

Here, the typical KIM API build and install process is detailed and the
system-collection is populated with the example MDs, PMs, and SMs, as well as a
single PM and its associated MD, both from openkim.org.  Additionally, one of
the example simulators is copied to the user's home directory and used to test
the KIM API.  The KIM API package uses the CMake build system.  See the CMake
documentation (https://cmake.org/cmake/help/v3.10/) for help with CMake
settings.  For some common CMake settings and KIM API specific settings, see
D.2 below.

The commands given below are for the bash shell.

By default packages are installed to the Global prefix directory "/usr/local".
Here we assume that "/usr/local/bin" is included as part of the system's
standard PATH setting.

First, we will create a working space and obtain the source package

   $ export WORKSPACE="${HOME}/kim-api-workspace"
   $ mkdir "${WORKSPACE}"
   $ cd "${WORKSPACE}
   $ wget https://s3.openkim.org/kim-api/kim-api-X.Y.Z.txz  # replace X, Y, and Z with the current version numbers
   $ tar Jxvf kim-api-X.Y.Z.txz
   $ cd kim-api-X.Y.Z

We will set an environment variable to point the the KIM API source.

   $ export KIM_API_SOURCE="${WORKSPACE}/kim-api-X.Y.Z"  # replace X, Y, and Z with the current version numbers

Next the configuration and build process begins.  (Note: lines beginning with
"$", without leading whitespace, in this file are extracted and used in the KIM
API automated Continuous-Integration (CI) testing framework.)

$ cd "${WORKSPACE}"
$ mkdir build
$ cd build
$ cmake ${KIM_API_SOURCE} -DCMAKE_BUILD_TYPE=Release
$ make -j2

If you want, build the documentation.

$ make docs

If you want, before installing the package, you can run the tests.

$ make test

Now, install the package (and docs, if built).

$ sudo make install
$ sudo ldconfig  # All linux systems should do this; on Redhat-like systems you may need to first add /usr/local/lib to /etc/ld.so.conf
$ cp -r "${KIM_API_SOURCE}/examples/simulators/utility_forces_numer_deriv" "${WORKSPACE}/"
$ cd "${WORKSPACE}"

If you want, you can now delete the source and build tree.  However, you may
also want to preserve the "install_manifest.txt" file which would be needed for
uninstalling the KIM API package (see D.4 below).

   $ cp "${WORKSPACE}/build/install_manifest.txt" "${WORKSPACE}/install_manifest.txt"
   $ rm -r "${WORKSPACE}/build

Now, we can build the simulator using the KIM API library that we have just
installed.

$ cd utility_forces_numer_deriv
$ mkdir build
$ cd build
$ cmake ..
$ make

Try it with one of the example models:

$ printf "ex_model_Ar_P_LJ" | ./utility_forces_numer_deriv

Next, we can try it with a model installed from https://openkim.org:

$ kim-api-collections-management install system --sudo EDIP_JustoBazantKaxiras_1998_Si__MO_958932894036_002
$ printf "EDIP_JustoBazantKaxiras_1998_Si__MO_958932894036_002" | ./utility_forces_numer_deriv

Congratulations, you have now successfully installed the KIM API.  If you would
like to learn more about the KIM API, read the documentation in the docs
directory (/usr/local/share/doc/kim-api).

If you would like to install the latest release of all models from
https://openkim.org, you can do:

   $ kim-api-collections-management install system --sudo OpenKIM

D.2 CMAKE BUILD OPTIONS

The KIM API defines a number of specific build options which are detailed in
this section.  But first, some notes about a few important standard CMake
options.

D.2.1 COMPILER SELECTION

By default CMake will search for appropriate compilers available on your
system.  Generally, it selects reasonable choices.  However, if you wish to
force CMake to use specific compilers, you can do so with environment variables
set on the command line.  For example, suppose you have the latest GNU Compiler
Collection (GCC) version X installed with the compilers named 'gcc-X', 'g++-X',
and 'gfortran-X', for the C, C++, and Fortran compilers, respectively.  Then,
to force CMake to use these compilers, replace the command (from above)

   $ cmake .. -DCMAKE_BUILD_TYPE=Release

with

   $ CC=gcc-X CXX=g++-X FC=gfortran-X cmake .. -DCMAKE_BUILD_TYPE=Release

D.2.2 CMAKE_BUILD_TYPE

CMake defines the option CMAKE_BUILD_TYPE which can be set to "Debug",
"Release", "RelWithDebInfo", "MinSizeRel", or it can be empty.  (See the CMake
documentation for more details.)  By default CMAKE_BUILD_TYPE is empty.  In
short, while developing code or debugging, the value of "Debug" or
"RelWithDebInfo" should be used.  When building for production runs one of the
other values should be used.

D.2.3 INSTALLATION PREFIX

Here and below, all paths or filepaths must be specified in a format
appropriate for the OS (windows or linux).  Windows paths are of the form
C:\dir1\dir2 (forward slashes may be used instead to avoid escaping issues:
C:/dir1/dir2) and linux paths are of the form /dir1/dir2.

By default CMake installs the KIM API package under the Global prefix
"/usr/local".  This is referred to as a "Global" (or system-wide) installation.
It is available to all users of the system.  (Other "Global" prefix values are
"/" and "/usr".)  However, such installations require root user permissions (as
implied by the use of the "sudo" command above).  If you do not have root user
permission and/or do not want to install the KIM API to the global location,
you can change where CMake installs the KIM API by replacing the command (from
above)

   $ cmake .. -DCMAKE_BUILD_TYPE=Release

with

   $ cmake .. -DCMAKE_INSTALL_PREFIX="/install/prefix/path" -DCMAKE_BUILD_TYPE=Release

where "/install/prefix/path" should be replaced with your desired prefix.  For
example, to install the KIM API in the "local" subdirectory of your home
directory, use "${HOME}/local".  When installed in such a directory, the user
may employ the "kim-api-activate" utility to setup the PATH and bash
completions.  For example:

   $ source ${HOME}/local/bin/kim-api-activate

D.2.4 KIM API SPECIFIC BUILD OPTIONS

The KIM API defines two additional regular build options and additional
advanced options.

* KIM_API_LOG_MAXIMUM_LEVEL (="DEBUG" if CMAKE_BUILD_TYPE is "Debug", otherwise
  ="INFORMATION") This option takes one of the following six values "SILENT",
  "FATAL", "ERROR", "WARNING", "INFORMATION", "DEBUG".  This value controls, at
  compile-time, which type of log messages can be printed to the "kim.log"
  file.

* KIM_API_BUILD_EXAMPLES (=ON) When ON CMake will build the example MDs, PMs,
  SMs and Simulators.  NOTE: this option may be removed/changed in future
  releases when the examples are incorporated into the documentation.

Additionally, the KIM API defines the following advanced build options.

* KIM_API_PROJECT_NAME (="kim-api") This value controls the naming of many
  aspects of the package build.  Generally this should not be changed.  It can
  be used to build and install, on the same machine, two different copies
  (typically different versions) of the package.

* KIM_API_BASE64_BUFFERSIZE (="16777216") Sets the buffer size for the C++
  base64 encode/decode routines used in the kim-api.

* KIM_API_ENABLE_SANITIZE (=OFF) When ON this enables the AddressSanitizer
  library for detecting memory corruption bugs.

* KIM_API_ENABLE_COVERAGE (=OFF) When ON this enables gcov code coverage.

* KIM_API_CONFIGURATION_TIMESTAMP (=<utc-time-of-cmake-configuration>) This is
  used as part of the <kim-api-uid> universal ID for the kim-api installation.

* KIM_API_CMAKE_C_COMPILER (="${CMAKE_C_COMPILER}") This value is recorded and
  used after installation for compilation of items (MDs, PMs, SMs, etc.) to
  ensure binary compatibility with the installed KIM API.

* KIM_API_CMAKE_CXX_COMPILER (="${CMAKE_CXX_COMPILER}") This value is recorded
  and used after installation for compilation of items (MDs, PMs, SMs, etc.)
  to ensure binary compatibility with the installed KIM API.

* KIM_API_CMAKE_Fortran_COMPILER (="${CMAKE_Fortran_COMPILER}") This value is
  recorded and used after installation for compilation of items (MDs, PMs, SMs,
  etc.) to ensure binary compatibility with the installed KIM API.

* KIM_API_USER_CONFIGURATION_FILE (=".${PROJECT_NAME}/config") This value
  determines the default name of the KIM API user configuration file.  If the
  value corresponds to a relative path (does not start with "/"), then it is
  interpreted as relative to the user's home directory "${HOME}".

* KIM_API_USER_MODEL_DRIVERS_DIR_DEFAULT
  (="~/.${PROJECT_NAME}/<kim-api-uid>/model-drivers") This value specifies the
  default colon ':' (semicolon ';' on windows) separated list of the MD
  directory locations for the user collection.

* KIM_API_USER_PORTABLE_MODELS_DIR_DEFAULT
  (="~/.${PROJECT_NAME}/<kim-api-uid>/portable-drivers") This value specifies
  the default colon ':' (semicolon ';' on windows) separated list of the PM
  directory locations for the user collection.

* KIM_API_USER_SIMULATOR_MODELS_DIR_DEFAULT
  (="~/.${PROJECT_NAME}/<kim-api-uid>/simulator-models") This value specifies
  the default colon ':' (semicolon ';' on windows) separated list of the SM
  directory locations for the user collection.

* KIM_API_SYSTEM_MODEL_DRIVERS_DIR
  (="${CMAKE_INSTALL_FULL_LIBDIR}/${PROJECT_NAME}/model-drivers") This value
  specifies a colon ':' (semicolon ';' on windows) separated list of the MD
  directory locations in the system collection.  If the value starts with a
  colon (semicolon on windows), cmake will update it by prepending the default
  value.

* KIM_API_SYSTEM_PORTABLE_MODELS_DIR
  (="${CMAKE_INSTALL_FULL_LIBDIR}/${PROJECT_NAME}/portable-models") This value
  specifies a colon ':' (semicolon ';' on windows) separated list of the PM
  directory locations in the system collection.  If the value starts with a
  colon (semicolon on windows), cmake will update it by prepending the default
  value.

* KIM_API_SYSTEM_SIMULATOR_MODELS_DIR
  (="${CMAKE_INSTALL_FULL_LIBDIR}/${PROJECT_NAME}/simulator-models") This value
  specifies a colon ':' (semicolon ';' on windows) separated list of the SM
  directory locations in the system collection.  If the value starts with a
  colon (semicolon on windows), cmake will update it by prepending the default
  value.

D.3 Installing multiple versions

On linux and macOS systems if you intend to install multiple versions of the
KIM API using the same installation prefix
("-DCMAKE_INSTALL_PREFIX=/install/prefix/path" argument to cmake) you must take
care that the installations do not overwrite each other.  If you intend to
install multiple versions using the same prefix you must use the
"-DKIM_API_PROJECT_NAME=project-name" argument (See D.2.4 above) to cmake and
use a unique value (any string without whitespace or control characters is
valid) for each installation.

Full support for the "-DKIM_API_PROJECT_NAME" argument, as described here, was
first available in v2.0.2.  For example, suppose the current version of the KIM
API were v3.2.1, and you want to also install KIM API v3.0.0, and v2.1.1.
Then, you would configure each version as follows:

 * v3.2.1

   $ cmake .. [additional args]  # use default ("kim-api") for current version.

 * v3.0.0

   $ cmake .. -DKIM_API_PROJECT_NAME=kim-api3.0 [additional args]

 * v2.1.1

   $ cmake .. -DKIM_API_PROJECT_NAME=kim-api2.1 [additional args]

D.4 Uninstall the KIM API

When the KIM API package is installed, CMake creates a file in the build tree
named "install_manifest.txt".  For the above commands this file would be
located at "${HOME}/kim-api-X.Y.Z/build/install_manifest.txt".  The manifest
file contains the absolute file name of every file installed as part of the KIM
API package.  The contents of the install_manifest.txt file can be used to
remove these files and, thus, uninstall the KIM API package.  Thus, the
install_manifest.txt file should be saved for later use, if necessary.

For example, the following commands could be used to uninstall the KIM API
package (assuming the "install_manifest.txt" file is located in your home
directory).

   $ cd "${HOME}"
   $ while read line || test -n "${line}"; do sudo rm -f "${line}"; done < install_manifest.txt

A more sophisticated set of commands could also remove any empty subdirectories
left behind by this process.

It may also be desirable to remove the user configuration file and user
collection directories.

   $ rm -rf "${HOME}/.kim-api"


-------------------------------------------------------------------------------

E. ADDING MDs, PMs, and SMs TO THE COLLECTIONS


Here we describe how to add MDs, PMs, and SMs to the system-collection,
user-collection, environment-variable-collection, and the CWD-collection.

E.1 ADDING MDs, PMs, and SMs TO THE SYSTEM-COLLECTION

Once you have the KIM API installed, it is easy to add additional MDs, PMs, and
SMs to the system-collection.

$ cd "${WORKSPACE}"

$ kim-api-collections-management install system --sudo Morse_Shifted_Jelinek_1972_Ar__MO_831902330215_003
$ kim-api-collections-management install system --sudo Sim_LAMMPS_ADP_PunDarlingKecskes_2015_CuTa__SM_399364650444_000

The kim-api-collections-management utility automatically installs the necessary
MD too.  You can see the items in the various collections by executing the
following command.

$ kim-api-collections-management list

Now we can test the newly installed PM.

$ cd "${WORKSPACE}/utility_forces_numer_deriv/build"  # we'll assume this is already built
$ printf "Morse_Shifted_Jelinek_1972_Ar__MO_831902330215_003" | ./utility_forces_numer_deriv

E.2 ADDING MDs, PMs, and SMs TO THE USER-COLLECTION

Adding MDs, PSs, and SMs to the user-collection is similar.

$ cd "${WORKSPACE}"

$ kim-api-collections-management install user LJ_Shifted_Bernardes_1958HighCutoff_Ar__MO_242741380554_003
$ kim-api-collections-management install user Sim_LAMMPS_AGNI_BotuBatraChapman_2017_Al__SM_666183636896_000
$ kim-api-collections-management list
$ cd "${WORKSPACE}/utility_forces_numer_deriv/build"  # we'll assume this is already built
$ printf "LJ_Shifted_Bernardes_1958HighCutoff_Ar__MO_242741380554_003" | ./utility_forces_numer_deriv

E.3 ADDING MDs, PMs, and SMs TO THE ENVIRONMENT-VARIABLE-COLLECTION

Adding MDs, PMs, and SMs to the environment-variable-collection is similar.

$ cd "${WORKSPACE}"

$ mkdir -p "${WORKSPACE}/my-env-collection/model-drivers"
$ export KIM_API_MODEL_DRIVERS_DIR="${WORKSPACE}/my-env-collection/model-drivers"
$ mkdir -p "${WORKSPACE}/my-env-collection/portable-models"
$ export KIM_API_PORTABLE_MODELS_DIR="${WORKSPACE}/my-env-collection/portable-models"
$ mkdir -p "${WORKSPACE}/my-env-collection/simulator-models"
$ export KIM_API_SIMULATOR_MODELS_DIR="${WORKSPACE}/my-env-collection/simulator-models"
$ kim-api-collections-management install environment Morse_Shifted_GirifalcoWeizer_1959HighCutoff_Cu__MO_151002396060_003
$ kim-api-collections-management install environment Sim_LAMMPS_BOP_WardZhouWong_2012_CdZnTe__SM_409035133405_000
$ kim-api-collections-management list
$ cd "${WORKSPACE}/utility_forces_numer_deriv/build"  # we'll assume this is already built
$ printf "Morse_Shifted_GirifalcoWeizer_1959HighCutoff_Cu__MO_151002396060_003" | ./utility_forces_numer_deriv

E.4 ADDING MDs, PMs, and SMs TO THE CWD-COLLECTION

Adding MDs, PMs, and SMs to the CWD-collection is, again, similar.

$ cd "${WORKSPACE}"

$ kim-api-collections-management install CWD Exp6_KongChakrabarty_1973_ArNe__MO_946046425752_002
$ kim-api-collections-management install CWD Sim_LAMMPS_MEAM_EtesamiAsadi_2018_Ni__SM_333792531460_000
$ kim-api-collections-management list
$ printf "Exp6_KongChakrabarty_1973_ArNe__MO_946046425752_002" | "${WORKSPACE}/utility_forces_numer_deriv/build/utility_forces_numer_deriv"  # we'll assume this is already built

E.5 Adding MDs, PMs, and SMs from a local source directory

The kim-api-collections-management utility allows for the installation of items
from a directory on the local file system.  This is useful if you are
developing an item or do not have network access to openkim.org, but already
have the source code downloaded.  We'll assume that the item's source code
(including the CMakeLists.txt file, parameter files, etc) you want to install
are in directory "${WORKSPACE}/item-source".  Then you simply provide this
directory name instead of the item name.

   $ kim-api-collections-management install user "${WORKSPACE}/item-source"

E.6 Manually adding MDs, PMs, and SMs

If necessary a MD, PM, or SM may be manually built and installed.  We'll assume
the item's source code is in the current directory

   $ mkdir build
   $ cd build
   $ cmake .. -DKIM_API_INSTALL_COLLECTION=SYSTEM
   $ make
   $ sudo make install

The KIM_API_INSTALL_COLLECTION variable can also take values USER and
ENVIRONMENT.
