ASAP - As Soon As Possible
ASAP is a calculator for doing large-scale classical molecular dynamics within the Campos Atomic Simulation Environment (ASE).
Asap now supports Python 3.5 or later, but Python 3.7 is recommended. Asap can now be installed with pip install asap3.
ASAP currently implements:
- The Effective Medium Theory (EMT) potential for the elements Ni, Cu, Pd, Ag, Pt and Au (and their alloys). There is also experimental support for CuMg and CuZr alloys.
- Support for all models published by the OpenKIM.org project. Currently, more than 150 potentials are available this way. See the page OpenKIM support.
- A number of experimental or in-development potentials.
ASAP supports simulations on parallel clusters. Simulations with hundreds of CPU cores are possible with little overhead.

- Version 3.3.5 was released 12. August 2010. It maintains compatibility with the newest version of ASE.
- Version 3.2.6 was released 7. December 2009. It is a bug fix release, fixing a way too high memory consumption in parallel simulations with many CPUs, and an occational crash in long, parallel simulations. It also introduces asap-qsub, a tool for easy job submission on Niflheim.
- Version 3.2.0 was released 20. August 2009. Asap version 2.X is now obsolete and unsupported!
- The 20. August 2009: SVN repository reorganisation, in preparation for releasing version 3.2.
- Version 3.0.2 was released 15. October 2008. This is the first version for ASE version 3.X. Please see the page Differences between asap version 2 and 3.
- Version 2.20.0 was released 11. July 2008. Performance enhancements for Monte Carlo EMT simulations and for multithreaded MD simulations.
- Version 2.18 was released 12. March 2008, with two new potentials and a new parallelization paradigm.
- The Asap source code has moved from CVS to SVN and the bug tracking from Bugzilla to trac (November 2007).
- Information about Performance added 22. November 2006.
- Version 2.16.1 was released 27. October 2006. Mainly some internal changes and a few minor bugfixes. Now works on the Opteron CPUs (such as the Niflheim cluster).
- Version 2.14 was released 29. November 2005. NPT dynamics now work in parallel simulations. A memory leak relating to NPT dynamics was removed.
- Version 2.12 was released 15. November 2005. It requires Campos ASE version 2.1. It contains a few minor bug fixes, and support for generating general crystal structures.
- Version 2.10 was released 16. July 2005. It provides compatibility with newer versions of SWIG (1.3.23 or newer). If you get weird messages about overloaded functions when calculating the stress, update to this version.
- Version 2.8 was released 23. May 2005. Mainly a bug fix release (including a nasty one, where the zero of the potential energy could be in different places). New feature: the Subset filter can now be used in parallel simulations.
- Version 2.6.1 was released 20. April 2005. The only change from version 2.6 is that the Distutils-based installation (python setup.py install) now works again.
- Version 2.6 has been released 15. April 2005. A few extra modules have been added, mainly for analysis, and a few bugs have been fixed. Asap no longer requires cblas for some analysis tools.
