By 18 – 21 January 2016 – Trieste, Italy
DESCRIPTION
The Quantum ESPRESSO (QE) project has started in 2002 by collecting together PWscf, CP, PHonon, and other smaller codes, and has been very rapidly evolving in many directions and inevitably increasing its complexity. In particular, one of such directions is the development of codes based on linear response theory (e.g. such components as PHonon, TDDFPT, GIPAW, BSE, etc.). Many groups worldwide are working independently on linear-response developments, resulting in many different, independent, and often conflicting branches of core QE codes. Therefore, there is a need of unification and restructuring of the linear-response codes of QE and creation of a modular system that has to be well documented.
The goal of the present meeting is to bring together developers of the QE distribution, working on linear response, and to work together on a modularization, restructuring, and unification of various linear-response codes.
This developers’ meeting will be supported by the Quantum ESPRESSO Foundation and the MaX European Centre of Excellence.
