Abstract: Background

With the improvement of computing power and the rise of high-throughput computing, researchers usually need to perform a large number of repeated instructions to submit scientific tasks and further check their computational results during material theoretical calculations. Generally, these instructions are simple, cumbersome and time consuming.


This study aims to improve the efficiency of scientific calculations by using VASP code.


The material theory calculation assistant program, VaspCZ, developed by using Python languages, is summarized to form a general github open source project, which provides detailed user documents, examples and application programming interfaces (API).


VaspCZ, an efficient VASP computation assistant program includes two parts: the software part and API part. The software part provides the command line user interface, which enabled the researchers to complete the VASP calculations with the basic Linux command. The API part provides the bottom layer library to realize the custom calculation (such as high-throughput calculation, writing advanced application, etc.) for the researchers with python experiences.


It is proved by practice that the efficiency of theoretical calculation of materials using VASP can be significantly improved by aid of this assistant program.

Key words: First-principles, VASP, assistant program, electronic structure calculation, transient state calculation
