A Web Application for Fitting Experimental Data Using JINR Cloud Infrastructure and ROOT Package Tools

The FITTER_WEB application was developed to solve the problems of fitting experimental data with multiparameter theoretical functions which model the objects under study. The user is given full control over the fitting process, as well as the ability to use the built-in ROOT mechanisms of parallelism. The contribution describes the structure of the web application, the software tools used for its development, and the specifics of deployment to the JINR cloud infrastructure. The results of the parallel FITTER_WEB analysis of the small-angle scattering data on a samples of polydispersed populations of phospholipid-based unilamellar vesicles are presented. The possibilities of optimizing the web application operation by the allocation of computing resources in the JINR cloud, as well as multi-user calculations, are discussed.
