CONQUEST is a large scale DFT electronic structure code, capable of both diagonalisation and linear scaling, or O(N), calculations. It is developed jointly by NIMS (National Institute for Materials Science, Japan), ISM (Institut des Science Moleculaires, University of Bordeaux) and UCL. The code is designed to perform DFT calculations on very large systems (containing tens of thousands, hundreds of thousands or even millions of atoms) though is also very fast for smaller systems, and scales exceptionally well with numbers of processes. It can be run at different levels of precision, ranging from ab initio tight binding up to full DFT with plane wave accuracy. It is capable of operation on a range of platforms from workstations up to high performance computing centres. These web pages contain information on the code, and its applications, as well as separate areas for developers.
The code is presently on v1.1, with v1.2 to be released in July 2023. It is a complete, robust code which is compatible with a very accurate library of pseudopotentials, PseudoDojo. We welcome bug reports and suggestions for improvement through the GitHub issues page. We are very happy to welcome new users and developers.
