From the 2015 fiscal year, the supercomputer center has started the project for the advancement of software usability in materials science to enhance the usability of the supercomputer system of ISSP. We develop and enhance the usability of programs adopted in this project, release them as open-source software, and support dissemination activities such as supporting hands-on lectures. In addition to these activities, using the developed software packages, we theoretically study research subjects such as the derivation and analysis of experimental data and the estimation of effective model parameters using Bayesian optimization and Monte Carlo methods.
