Abstract

In work the structure and separate components of the cloudy service intended for the solution of multi-scale problems of nanotechnology on supercomputer systems are presented. The need of integration: (a) an ideas and knowledge on this applied problem, (b) a specialists in this scientific field and a programmers for the supercomputer systems, (c) various technologies of modeling and a set of packages of applied programs, (d) various computing resources which are available for the Institute and its partners – was motivation to creation of cloudy service. The prototype of the cloudy environment realized in the form of service Multilogin and the applied software available on virtual machines of users became a results of this work. The first applications of created service are (a) the Flow_and_Particles parallel program for supercomputer calculations of multi-scale gasdynamics processes in micro-channels of technical systems and (b) the Flow_and_Particles_View visualizer of distributed computation results. Use of the developed service allowed to increase efficiency of scientific research in the chosen applied field. In particular, by means of the developed service it was succeeded to calculate and analyze details of interaction of nitrogen stream with a nickel surface. This problem is characterized by large volume of calculated data. For example, representative selection of the control points relating to various time-points borrows in the sum of 3-4 Tb for each variant of calculation. By means of the developed software it was succeeded not only to keep these distributed data, but also to construct according to them necessary graphical diagrams and video.
