A new approach to integration of computing clusters for higher total performance is presented. the limits arising from local addressing of nodes in the clusters are overcome. the architecture of inter-cluster communication service, the functions of its components, and a model of application management based on the Service are considered. the dependence of the number of inter-cluster communication channels on the number of clusters and processes of a parallel application is shown. Results of performance tests of the Service are illustrated by a model and real systems of two closed clusters. Efficiency of utilizing the Service is shown in comparison with utilizing low-level functions of the protocol TCP/IP.
