Creation of systems of the distributed computing is the new perspective tendency of development of computing systems. To one of actual problems began maintenance of portable of the software of clustered sites. In this article it is offered to use existing means of a virtualization of the computing environment (system VMWare or similar) for simplification of creation of the software of systems of the distributed calculations. Results of measurement of parameters of a bandwidth and a latency of system of synchronization of a cluster for virtual and real nodes are submitted. Results of the made researches allow recommending use of virtual clusters for simplification of creation of systems of the distributed calculations. PACS: 89.80.+h, 89.70.+c, 01.10.Hx 1
