Distributed simulation of agent-based systems with HLA
Michael Lees, Brian Logan, Georgios Theodoropoulos
Article No.: 11
DOI: 10.1145/1243991.1243992

In this article we describe HLA_AGENT, a tool for the distributed simulation of agent-based systems, which integrates the SIM_AGENT agent toolkit and the High Level Architecture (HLA) simulator interoperability framework. HLA_AGENT offers enhanced...

A Co-Plot analysis of logs and models of parallel workloads
David Talby, Dror G. Feitelson, Adi Raveh
Article No.: 12
DOI: 10.1145/1243991.1243993

We present a multivariate analysis technique called Co-Plot that is especially suitable for few samples of many variables. Co-Plot embeds the multidimensional samples in two dimensions, in a way that allows key variables to be identified, and...

Simulation output analysis using integrated paths
James M. Calvin
Article No.: 13
DOI: 10.1145/1243991.1243994

This article considers the steady-state simulation output analysis problem for a process that satisfies a functional central limit theorem. We construct an estimator for the time-average variance constant that is based on iterated integrations of...

Importance sampling for sums of random variables with regularly varying tails
Paul Dupuis, Kevin Leder, Hui Wang
Article No.: 14
DOI: 10.1145/1243991.1243995

Importance sampling is a variance reduction technique for efficient estimation of rare-event probabilities by Monte Carlo. For random variables with heavy tails there is little consensus on how to choose the change of measure used in importance...
