LiFlow web service for quick launch of large experiment series on supercomputers

In many fields of research, for example in simulations of living systems, the automatic execution of many numerical experiments with varying parameters is a crucial task. We propose a web-based multiplatform service for launching a series of experiments on a supercomputer. The service interface allows the user to set parameters and run jobs on a supercomputer without working in the command line. The system minimizes the number of user actions required for launching a large series of experiments. Using the built-in database, one of the previously conducted experiments can be picked up and quickly restarted with new settings. We provide the architecture of interaction between a computing cluster, a database, and an external web application, as well as the algorithm for generating tuples from sets of values of individual parameters, and features of the graphical user interface. The system actively carries out computational experiments to study the drift of spiral waves in the myocardium on the Uran supercomputer, Ekaterinburg. (C) 2018 The Authors. Published by Elsevier B.V.
