In this paper, the authors describes development, realization and verification of more precise analytical models for the study of the basic performance parameters of parallel computers based on connected parallel computers (cluster, Network Of Workstation (NOW), grid). At first the paper describes very shortly the developing steps of parallel computer architecture and then summarized the basic concepts for performance modeling of mentioned parallel computers. To illustrate theoretical evaluation concepts the paper considers in its experimental part the achieved results on concrete analyzed examples and their comparison. The suggested model considers for every node of the NOW or grid networks one part for the own workstation's activities and another one for node's communication channel modeling of performed data communications.
