Execution Time Requirements of Petri Net Programs in a Sun Workstation Environment.

摘要

The study described in this paper was done in the context of a Petri net model (generalized stochastic Petri net or GSPN model) of a simulation network similar to SIMNET, a distributed system of training simulators connected over an Ethernet local area network. In this report, the execution time of a stochastic Petri net model of a specific distributed application using Ethernet is used to determine the largest model that can be analyzed on a Sun workstation in a reasonable time. The time for the solution of the SIMNET models was measured using two different configurations of the Sun Workstation. The data collected indicates that increasing the storage capacity of the workstation increases the size of the model that can be solved in a reasonable time. The degradation in performance with an increasing number of markings is more gradual with larger memory. A number of tables are included in the report which illustrate the outcome for each of the three models examined. (Author). (kr)
