Computer performance modeling of possibly complex computations running on highly concurrent systems is considered. Earlier work in this area either dealt with a very simple program structure or resulted in methods with exponential complexity. An efficient procedure is developed to compute the performance measures for series-parallel-reducible task systems(More)
Queueing Network Models - QNM's with population size constraints and delayed blocked customers occur due to MultiProgramming Level - MPL constraints in computer systems and window flow-control mechanisms in Computer Communication Networks - CCN's. The computational cost of existing algorithms is unacceptable for large numbers of chains and high population(More)
A method for analyzing the performance of computer communication networks using queueing network models (QNM's) is presented in this paper. The user/computer sites are interconnected by a wide-area network with an end-to-end window flow-control mechanism. The QNM for the system including the communication subnet and the host computers is intractable because(More)
This paper deals with the analysis of large-scale closed There have been numerous studies dealing with the queueing network (QN) models which are used for the performance analysis of multiprogrammed computer systems using QN analysis of computer communication networks (CCN's). The computer systems are interconnected by a wide-area network. Users accessing(More)
