About the High-Throughput Toolkit

The High-Throughput Toolkit (httk) is a toolkit for preparing and running calculations, analyzing the results, and store them in a global and/or in a personalized database. httk is an independent implementation of the database-centric high-throughput methodology pioneered by Ceder et al., and others. [see, e.g., Comp. Mat. Sci. 50, 2295 (2011)]. httk is presently targeted at atomistic calculations in materials science and electronic structure, but aims to be extended into a library useful also outside those areas.

Installation information is found in the httk Installation Instructions.

User’s guide

For information on basic usage of the httk, see httk Users’ Guide.

More tricky details on how high-throughput computational tasks are executed via the program are presented in httk Runmanager Details. This is useful if you plan to write your own intricate run-scripts using httk.

Reporting bugs

We track our bugs using the issue tracker at github. If you find a bug, please search to see if someone else has reported it here:

Citing httk in scientific works

This is presently the preferred citation to the httk framework itself:

The High-Throughput Toolkit (httk), R. Armiento et al.,

Since the httk can call upon many other pieces of software quite transparently, it may not be initially obvious what other software should be cited. Unless configured otherwise, httk prints out a list of citations when the program ends. You should take note of those citations and include them in your publications if relevant.


For a more complete list of contributors and contributions, see httk Contributors.


httk has kindly been funded in part by:
  • The Swedish Research Council (VR) Grant No. 621-2011-4249
  • The Linnaeus Environment at Linköping on Nanoscale Functional Materials (LiLi-NFM) funded by the Swedish Research Council (VR).
