The high-throughput DFT calculations are handled within PyLada, a modular Python framework to control first-principles calculations, which not only creates the required VASP files and storage folder structure but also interfaces with the job queuing system on parallel processing supercomputing clusters. PyLada offers a variety of useful in-built tools for constructing and manipulating periodic crystal structures, for manipulating functionals and extracting their output, and for checking the results from thousands of calculations simultaneously.
