How to download?
Quantum ESPRESSO is currently distributed as source packages, but selected binary packages for Linux and Windows are also available. Since v.5.0 the distribution is split into a base distribution and various specialized packages and plug-ins. These packages can be automatically downloaded and installed on demand after the installation of the base distribution: see the general documentation for more information.
The current stable version, v.5.1.1, and the previous ones until v.4.1.3 can be downloaded from the download page of the developers’ portal QE-forge. Here one can also find binary packages for Windows, courtesy of Axel Kohlmeyer, and the GPU-enabled version, courtesy of Filippo Spiga. About the latter: please see the q-e-gpu project QE-forge page for more information, download and installation instructions.
Binary packages for Linux are available in the Debian stable and testing distributions, courtesy of DebiChem maintainers.
