Ab initio quantum Monte Carlo study involves many complicated operations such as generating trial wave functions, optimizing variational parameters, and time-step (lattice-size) extrapolations. Automation of such tasks can decrease the required time for our work and reduce human errors as much as possible. We have recently developed a python suite named "TurboGenius" that allows us to implement workflows with ab initio quantum Monte Carlo code, "TurboRVB" [K. Nakano et al., J. Chem. Phys. 152, 204121 (2020)]. TurboGenius is implemented by Python 3 in an object-oriented fashion. Users can utilize the provided modules as workflow templates or use the modules in their python scripts. TurboGenius also provides useful command-line interfaces by which users can quickly generate input files, run jobs, and analyze output results. In the presentation, I also show several scientifically new results, including high-throughput computations of binding energy calculations.
