pyiron is an integrated development environment for implementing, testing, and running simulations in computational materials science. It combines several tools in a common platform:
Atomic structure objects – compatible to the Atomic Simulation Environment (ASE).
Feedback Loops – to construct dynamic simulation life cycles.
Hierarchical data management – interfacing with storage resources like SQL and HDF5.
Integrated visualization – based on NGLview.
Interactive simulation protocols - based on Jupyter notebooks.
Object oriented job management – for scaling complex simulation protocols from single jobs to high-throughput simulations.
pyiron (called pyron) is developed in the Computational Materials Design department of Joerg Neugebauer at the Max Planck Institut für Eisenforschung (Max Planck Institute for iron research). While its original focus was to provide a framework to develop and run complex simulation protocols as needed for ab initio thermodynamics it quickly evolved into a versatile tool to manage a wide variety of simulation tasks. In 2016 the Interdisciplinary Centre for Advanced Materials Simulation (ICAMS) joined the development of the framework with a specific focus on high throughput applications. In 2018 pyiron was released as open-source project.
