The project will deploy and also continue the development of a cloud-based software as a service. The software performs computations of physical quantities of interest based on models of the first generations of galaxies in the Universe. The next step is to allow simple data analysis tasks to be performed using these models. Access to the software is provided through a web-based interface, to offer the scientific capability of the software to the Swedish and international research communities. Output will be numerical tables and visualization with plots. The existing code GalaxyMC, developed under several SNIC projects will continue to be adapted for this purpose. It is a parallellized mix of Fortran and Python code.
