AbstractThe NumGRID is a middleware for joining geographically distributed computational clusters in order to run large-scale scientific applications that use MPI standards for communication between processes. Intercluster communication system of the NumGRID provides a single communication environment for the processes located on internal nodes of joined clusters. The paper discusses shortcoming of the NumGRID v.1 implementations, suggests new principles for the NumGRID v.2 implementation and presents an experimental evaluation of this principles.
