Stochastic Petri nets (SPNs) are widely used for the performance evaluation of computer and telecommunication systems. They inherit from their untimed version the capability of modeling parallel computations in a simple, graphical way. Simulation of SPNs is an important way to assess the performance of a system measured as throughput, response time or expected number of customers/resources in some places. Perfect sampling allows for the selection of the initial state of a simulation with a probability which corresponds to its stationary probability and hence the warm-up period is not required any more. In this paper we present performance tests of spnps, a tool based on some previous works that implements perfect sampling algorithm for SPNs by using decision diagrams. We test performance of the tool on a class of stochastic models of great importance in the quantitative evaluation of distributed systems and communication networks: the fork-join queueing networks.

Abstract

Stochastic Petri nets (SPNs) are widely used for the performance evaluation of computer and telecommunication systems. They inherit from their untimed version the capability of modeling parallel computations in a simple, graphical way. Simulation of SPNs is an important way to assess the performance of a system measured as throughput, response time or expected number of customers/resources in some places. Perfect sampling allows for the selection of the initial state of a simulation with a probability which corresponds to its stationary probability and hence the warm-up period is not required any more. In this paper we present performance tests of spnps, a tool based on some previous works that implements perfect sampling algorithm for SPNs by using decision diagrams. We test performance of the tool on a class of stochastic models of great importance in the quantitative evaluation of distributed systems and communication networks: the fork-join queueing networks.
