Intensional Couplings in Variable-Structure Models: An Exploration Based on Multilevel-DEVS
Alexander Steiniger, Adelinde M. Uhrmacher
Article No.: 9
DOI: 10.1145/2818641

In modular, hierarchical modeling, couplings (connections) describe and constrain the communication, and thus interaction, between model components. Defining couplings between a large set of components in an extensional manner—listing all...

Computing Bayesian Means Using Simulation
Sigrún Andradóttir, Peter W. Glynn
Article No.: 10
DOI: 10.1145/2735631

This article is concerned with the estimation of α = E{r(Z)}, where Z is a random vector and the function values r(z) must be evaluated using simulation. Estimation problems of this...

FNM: An Enhanced Null-Message Algorithm for Parallel Simulation of Multicore Systems
Jun Wang, Zhenjiang Dong, Sudhakar Yalamanchili, George Riley
Article No.: 11
DOI: 10.1145/2735630

As multicore computer systems become increasingly complex, parallel simulation is becoming an important tool for exploring design space and evaluating design tradeoffs. The key to the success of parallel simulation is the ability to maintain a...

Parallel Expanded Event Simulation of Tightly Coupled Systems
Georg Kunz, Mirko Stoffers, Olaf Landsiedel, Klaus Wehrle, James Gross
Article No.: 12
DOI: 10.1145/2832909

The technical evolution of wireless communication technology and the need for accurately modeling these increasingly complex systems causes a steady growth in the complexity of simulation models. At the same time, multi-core systems have become...

MaD0: An Ultrafast Nonlinear Pseudorandom Number Generator
Jie Li, Jianliang Zheng, Paula Whitlock
Article No.: 13
DOI: 10.1145/2856693

In this article, we present MaD0, an ultrafast nonlinear pseudorandom number generator (PRNG) for noncryptographic applications. MaD0 uses byte-oriented operations for state initialization and fast integer-oriented operations for state transition...

Static Network Reliability Estimation under the Marshall-Olkin Copula
Zdravko I. Botev, Pierre L'Ecuyer, Richard Simard, Bruno Tuffin
Article No.: 14
DOI: 10.1145/2775106

In a static network reliability model, one typically assumes that the failures of the components of the network are independent. This simplifying assumption makes it possible to estimate the network reliability efficiently via specialized Monte...
