The article describes the impact of using virtual machines on the speed of concurrent computing. A concurrently running program for sorting data stored in an array was tested. The results of computing tests in a natively installed system and in a virtual machine environment were compared.Competition mechanisms drive technological progress in virtually every branch of the economy. In commercial and scientific applications, there is a particular drive to increase the computational speed of computers and, consequently, to shorten the time required for calculations. This allows for faster resolution of many computational problems in various areas of social life, such as: information retrieval, database usage, multimedia technologies, animation creation and computer graphics, virtual reality, modeling and optimization of economic and production processes, the pharmaceutical, petrochemical, and medical industries, etc. The production costs of standalone high-performance computing units are unprofitable. Such an approach seems impractical. For this purpose, it is reasonable to utilize the resultant computing power of multiple processors operating concurrently, which can be achieved through proper synchronization of their work. This can be accomplished by applying concurrent programming techniques. (…)
