For a particular choice of parameters, the algorithm provides a super astronomical period of $2^{19937} - 1$ and 623-dimensional equidistribution up to 32-bit accuracy, while using a working area of only 624 words. This is a new variant of the previously proposed generators, TGFSR, modified so as to admit a Mersenne-prime period. The characteristic polynomial has many terms. The distribution up to $v$ bits accuracy for $1 \leq v \leq 32$ is also shown to be good. An algorithm is also given that checks the primitivity of the characteristic polynomial of MT with computational complexity $O(p^2)$ where $p$ is the degree of the polynomial.\par We implemented this generator in portable C-code. It passed several stringent statistical tests, including diehard. Its speed is comparable to other modern generators. Its merits are due to the efficient algorithms that are unique to polynomial calculations over the two-element field.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Modeling and Computer Simulation", remark = "See remark in \cite{Plesser:2010:RSI} about bad initializers for the Mersenne Twister.", } @Article{Matsumoto:1998:SCA, author = "Makoto Matsumoto", title = "Simple cellular automata as pseudorandom $m$-sequence generators for built-in self-test", journal = j-TOMACS, volume = "8", number = "1", pages = "31--42", month = jan, year = "1998", CODEN = "ATMCEZ", ISSN = "1049-3301 (print), 1558-1195 (electronic)", ISSN-L = "1049-3301", bibdate = "Thu Aug 7 12:05:35 MDT 2003", bibsource = "http://www.acm.org/pubs/contents/journals/tomacs/; http://www.math.utah.edu/pub/tex/bib/tomacs.bib", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Modeling and Computer Simulation", } @Article{Hellekalek:1998:WST, author = "Peter Hellekalek and Harald Niederreiter", title = "The weighted spectral test: diaphony", journal = j-TOMACS, volume = "8", number = "1", pages = "43--60", month = jan, year = "1998", CODEN = "ATMCEZ", ISSN = "1049-3301 (print), 1558-1195 (electronic)", ISSN-L = "1049-3301", bibdate = "Thu Aug 7 12:05:35 MDT 2003", bibsource = "http://www.acm.org/pubs/contents/journals/tomacs/; http://www.math.utah.edu/pub/tex/bib/tomacs.bib", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Modeling and Computer Simulation", } @Article{Entacher:1998:BSW, author = "Karl Entacher", title = "Bad subsequences of well-known linear congruential pseudorandom number generators", journal = j-TOMACS, volume = "8", number = "1", pages = "61--70", month = jan, year = "1998", CODEN = "ATMCEZ", DOI = "http://dx.doi.org/10.1145/272991.273009", ISSN = "1049-3301 (print), 1558-1195 (electronic)", ISSN-L = "1049-3301", bibdate = "Thu Aug 7 12:05:35 MDT 2003", bibsource = "http://www.acm.org/pubs/contents/journals/tomacs/; http://www.math.utah.edu/pub/tex/bib/tomacs.bib", abstract = "We present a spectral test analysis of full-period subsequences with small step sizes generated by well-known linear congruential pseudorandom number generators.

General-purpose processors feature a large number of hardware mechanisms that aim to improve performance: caches, branch predictors, \ldots{}. The state of these components is not architectural (i.e., the result of an ordinary application does not depend on it). It is also volatile and cannot be directly monitored by the user.

The hardware clock cycle counter of the processor can be used to gather part of the entropy\slash uncertainty introduced by operating system interrupts in the internal states of the processor.

Often inversion by ``brute force'' is used, applying either very slow iterative methods or linear interpolation of the CDF and huge tables.

Hence, most microarchitecture design studies draw their conclusions from drastically truncated benchmark simulations that are often inaccurate and misleading. This article presents the Sampling Microarchitecture Simulation (SMARTS) framework as an approach to enable fast and accurate performance measurements of full-length benchmarks. SMARTS accelerates simulation by selectively measuring in detail only an appropriate benchmark subset. SMARTS prescribes a statistically sound procedure for configuring a systematic sampling simulation run to achieve a desired quantifiable confidence in estimates. Analysis of the SPEC CPU2000 benchmark suite shows that CPI and energy per instruction (EPI) can be estimated to within $\pm3\%$ with $99.7\%$ confidence by measuring fewer than 50 million instructions per benchmark. In practice, inaccuracy in microarchitectural state initialization introduces an additional uncertainty which we empirically bound to $\pm2\%$ for the tested benchmarks. Our implementation of SMARTS achieves an actual average error of only $0.64\%$ on CPI and $0.59\%$ on EPI for the tested benchmarks, running with average speedups of 35 and 60 over detailed simulation of 8-way and 16-way out-of-order processors, respectively.", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Modeling and Computer Simulation", } @Article{DeBoer:2006:ASI, author = "Pieter Tjerk {De Boer}", title = "Analysis of state-independent importance-sampling measures for the two-node tandem queue", journal = j-TOMACS, volume = "16", number = "3", pages = "225--250", month = jul, year = "2006", CODEN = "ATMCEZ", ISSN = "1049-3301 (print), 1558-1195 (electronic)", ISSN-L = "1049-3301", bibdate = "Wed Aug 23 15:29:47 MDT 2006", bibsource = "http://www.acm.org/pubs/contents/journals/tomacs/; http://www.math.utah.edu/pub/tex/bib/tomacs.bib", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Modeling and Computer Simulation", } @Article{Villen-Altamirano:2006:ERM, author = "Manuel Vill{\'e}n-Altamirano and Jos{\'e} Vill{\'e}n-Altamirano", title = "On the efficiency of {RESTART} for multidimensional state systems", journal = j-TOMACS, volume = "16", number = "3", pages = "251--279", month = jul, year = "2006", CODEN = "ATMCEZ", ISSN = "1049-3301 (print), 1558-1195 (electronic)", ISSN-L = "1049-3301", bibdate = "Wed Aug 23 15:29:47 MDT 2006", bibsource = "http://www.acm.org/pubs/contents/journals/tomacs/; http://www.math.utah.edu/pub/tex/bib/tomacs.bib", acknowledgement = ack-nhfb, fjournal = "ACM Transactions on Modeling and Computer Simulation", } @Article{Calvin:2006:SRM, author = "James M.

These probabilities arise in many applications including in PERT networks where our interest may be in measuring the probability of large project delays. We also develop provably asymptotically optimal importance sampling techniques to efficiently estimate these probabilities. In the light-tailed settings we show that an appropriate mixture of exponentially twisted distributions efficiently estimates these probabilities. As is well known, exponential twisting based methods are not applicable in the heavy-tailed settings. To remedy this, we develop techniques that rely on ?asymptotic hazard rate twisting? and prove their effectiveness in both light and heavy-tailed settings. We show that in many cases the latter may have implementation advantages over exponential twisting based methods in the light-tailed settings.

Co-Plot embeds the multidimensional samples in two dimensions, in a way that allows key variables to be identified, and relations between both variables and observations to be analyzed together. When applied to the workloads on parallel supercomputers, we find two stable perpendicular axes of highly correlated variables, one representing individual job attributes and the other representing multijob attributes. The different workloads, on the other hand, are rather different from one another, and may also change over time. Synthetic models for workload generation are also analyzed, and found to be reasonable in the sense that they span the same range of variable combinations as the real workloads.

However, by relying on the distribution of instantaneous derivative information, dead reckoning trades remote extrapolation accuracy for low computational complexity and ease-of-implementation. In this article, we present a novel extension of dead reckoning, termed neuro-reckoning, that seeks to replace the use of instantaneous velocity information with predictive velocity information in order to improve the accuracy of entity position extrapolation at remote hosts. Under our proposed neuro-reckoning approach, each controlling host employs a bank of neural network predictors trained to estimate future changes in entity velocity up to and including some maximum prediction horizon. The effect of each estimated change in velocity on the current entity position is simulated to produce an estimate for the likely position of the entity over some short time-span. Upon detecting an error threshold violation, the controlling host transmits a predictive velocity vector that extrapolates through the estimated position, as opposed to transmitting the instantaneous velocity vector. Such an approach succeeds in reducing the spatial error associated with remote extrapolation of entity state. Consequently, a further reduction in network traffic can be achieved.

To accommodate the extensive modeling and remodeling required to produce a credible model, we created an object-oriented simulation platform driven by a model-independent database within the .NET environment. The object-oriented structure not only encapsulated the needs of a simulation replication but created an extensible framework for specialization of the CRC components.

Vehicles in the inner area are simulated according to a microscopic simulation model including advanced submodels for driving behavior while vehicles in the outer areas are updated according to a less time-consuming mesoscopic simulation model. The presented work includes a new framework for generating and simulating vehicles within a moving area.

The framework has been validated on the number of vehicles that catch up with the driving simulator vehicle and vice versa. The agreement is good for active and passive catch-ups on rural roads and for passive catch-ups on freeways, but less good for active catch-ups on freeways.

Ongoing studies of the Internet's operations show that data loss and increased latency are occurring due to weaknesses in its interdomain routing protocol, BGP. Many solutions have been proposed, but few have experienced widespread adoption. Both the delayed discovery of the protocol's shortcomings, and apathy for its proposed solutions, are partially due to inadequate testing practices. Internet interdomain routing technologies are not evaluated at appropriate scale. Better testing is suggested, which incorporates the specification of large-scale experimental topologies. This is necessary, as BGP performs the distributed operation of interdomain routing across the thousands of networks composing the Internet. However, only small to moderately sized topologies can be currently accommodated by today's testing platforms.\par A modeling methodology based on path preserving scale-down is proposed to extend the topological scale of interdomain routing experimentation. A given Internet topology is reduced in terms of its autonomous systems (ASes) using a combination of Gaussian elimination and several graphical heuristics. The interdomain routing paths generated by BGP on this reduced topology are also preserved. Path preservation keeps the length, composition, and ordering of these routing paths unchanged. When the routing paths guiding Internet traffic among ASes are preserved across the size reduction, the large-scale traffic engineering induced by BGP can be estimated at much lower scales. Internet data losses due to certain inappropriate interdomain routing behaviors can be identified. As an example, a persistent multiple origin autonomous system (MOAS) conflict is characterized over a topology containing 8826 ASes.

The modeling methodology is similar to multidirectional medical tomography in that the spatial structure of an extended target can be reconstructed from a sequence of images obtained by scanning that target from several directions. Even though the controlled environment realized in diagnostic radiology cannot be replicated in the study of astrophysical phenomena, strong candidates for astrophysical tomography do exist in hot, close double stars locked in orbits around a common center of mass. As the Keplerian orbit is traced out, the geometry presented to the observer varies so that each star constitutes an analyzer upon its companion's wind and probes its structure. Since these targets are too far to be resolved spatially, we study and model the UV spectral lines of prominent wind ions, which scatter photospheric UV light so that line shapes vary as the stars revolve and as inhomogeneities form, propagate, and evolve in the composite wind. The framework presented is applied to two hot close binaries near the applicability limits of the discussed methodology. Two novel custom-made tools that aid the analysis of the spectra and the visualization of the results are also presented. The first of these, the {\em Spectrum Analyzer and Animator}, automates the derivation of light curves from the observed spectra and the generation of synthetic binary wind-line profiles, which reproduce the morphologies and variabilities of the observed wind profiles.

The focus of this article is to provide a practical guide for robust sensitivity, respectively, gradient estimation that can be easily implemented along the simulation of a DES. We study the Measure-Valued Differentiation (MVD) approach to sensitivity estimation. Specifically, we will exploit the ``modular'' structure of the MVD approach, by firstly providing measure-valued derivatives for input distributions that are of importance in practice, and subsequently, by showing that if an input distribution possesses a measure-valued derivative, then so does the overall Markov kernel modeling the system transitions. This simplifies the complexity of applying MVD drastically: one only has to study the measure-valued derivative of the input distribution, a measure-valued derivative of the associated Markov kernel is then given through a simple formula in canonical form. The derivative representations of the underlying simple distributions derived in this article can be stored in a computer library. Combined with the generic MVD estimator, this yields an automated gradient estimation procedure. The challenge in automating MVD so that it can be included into a simulation package is the verification of the integrability condition to guarantee that the estimators are unbiased. The key contribution of the article is that we establish a general condition for unbiasedness which is easily checked in applications.

However, these properties do not suffice to ensure that moments of order higher than one are well estimated. For example, they do not guarantee that the variance of the empirical variance remains under control as a function of the rarity parameter. We study generalizations of the BRE and LE properties that take care of this limitation. They are named bounded relative moment of order $k$ (BRM-$k$) and logarithmic efficiency of order $k$ (LE-$k$), where $k \geq 1$ is an arbitrary real number. We also introduce and examine a stronger notion called vanishing relative centered moment of order $k$, and exhibit examples where it holds. These properties are of interest for various estimators, including the empirical mean and the empirical variance. We develop (sufficient) Lyapunov-type conditions for these properties in a setting where state-dependent importance sampling (IS) is used to estimate first-passage time probabilities. We show how these conditions can guide us in the design of good IS schemes, that enjoy convenient asymptotic robustness properties, in the context of random walks with light-tailed and heavy-tailed increments.

This article develops asymptotically valid confidence intervals for quantiles estimated via simulation using variance-reduction techniques (VRTs). We establish our results within a general framework for VRTs, which we show includes importance sampling, stratified sampling, antithetic variates, and control variates. Our method for verifying asymptotic validity is to first demonstrate that a quantile estimator obtained via a VRT within our framework satisfies a Bahadur--Ghosh representation. We then exploit this to show that the quantile estimator obeys a central limit theorem (CLT) and to develop a consistent estimator for the variance constant appearing in the CLT, which enables us to construct a confidence interval.

The data presented by Kim et al. are thus individual realizations of a random walk and not suited to judge the quality of pseudorandom number generators.
