KIM API version 1.3.1 released

20-Jan-2014

The KIM development team is pleased to announce the release of version 1.3.1 of the KIM application programming interface (API). By conforming to this API, an atomistic simulation code will seamlessly work with any KIM-compliant interatomic model written in any supported language. This release includes updates to the make system, bug fixes, better support of CYGWIN systems, portability improvements, and a fix in order to work with gnu make 3.81.

Version 1.3.1 is a fully functioning API. It has the following main features:

  • licensed under the Open Source CDDL license
  • support for C, C++, FORTRAN 77, Fortran 90/95
  • partial support for Fortran 2003 (more information available on request)
  • support for static and dynamic linking of programs using the OpenKIM API
  • communication of an arbitrary number of `arguments’ to and from a Model
  • support for multiple particle types
  • enables a simulation code to access and modify Model parameters
  • support for physical units and unit conversions
  • support for six NBC (neighbor list and boundary conditions) methods
  • support for `Model drivers’ (Models that read in parameters)
  • built-in support for virial and Hessian calculations
  • up-to-date documentation

(See the CHANGELOG and README files described below for more information on these features.)

The distribution includes the API code, examples of simulation codes (Tests) and interatomic models (Models) and documentation.

To obtain the code, visit the following page:

https://openkim.org/kim-api/#download

and click on the link for the current release of the KIM API on the top of the page. Then do the following:

  1. Unpack the tarball (on Unix/Linux/Mac OSX systems, type: tar zxvf openkim-api-v1.3.1.tgz) which will create the directory openkim-api-v1.3.1
  2. Read the CHANGELOG file in the root directory (openkim-api-v1.3.1/CHANGELOG) to see what is new in the current release.
  3. Read the README file in the root directory (openkim-api-v1.3.1/README).
  4. Install the package. See directions in the INSTALL file in the root directory.
  5. Read the file README in the DOCs directory for a step-by-step guide to learning the API.
