Computational Science and Its Applications – ICCSA 2020

In this paper the virtual testbed as a problem-solving environment is considered in different aspects. Fundamental questions for virtual testbed development are (1) characteristics of mathematical models and their interaction; (2) computational aspects and mapping of algorithms onto hardware; (3) information streams and data smanagement. The authors propose the concept of a virtual private supercomputer as a tool for virtual testbed computer environment. Examples of the implementation of the virtual testbed in different areas are given. The article summarizes achievements of the authors in the field of virtual testbed during last years.
