Virtual computing environments: utilization on the GRID polygons

The article is devoted to the analysis of applying of various virtualization technologies in the distributed GRID environment including creation of the virtual computational and network resources as well as dynamically forming virtual program «containers» with support of various parallel program environments. The worked out methods make it possible to start different parallel supplements on random resource units of GRID polygons. As a case in point, the authors give preparation and launching of quantum-chemical GAMESS-US package in the distributed gLite environment on the basis of the polygon EGEE-RDIG resources.
