Nowadays approximately all software is distributed. Analysis of multiversinal software can be done on the basis of distributed systems of data processing. This paper shows on GERT-network example that the equivalent transforma-tions allow to simplify considerably the network and facilitate the search loops. GERT-networks simulate the behavior of Condor while the fixed-length modes computation without backup and migration (mode ˮVanillaˮ). Calculations which allow to obtain probabilistic characteristics of the given network are given. The various modes of the operation Condor, the advantages of distributed heterogeneous information processing systems are described.
