Optimistic Trace-driven Simulation

by Xiaohan Qin, Jean-loup Baer , 1994
"... Parallel simulation of multiprocessor architectures is a promising direction because a parallel system provides the high computation and storage capabilities that are required by detailed architectural simulation. Additionally, the behavior of the target system exhibits natural parallelism. In this ..."

. In this paper, we consider the evaluation of the memory hierarchy of multiprocessor systems via parallel trace-driven simulation. We present a Time Warp-like parallel trace-driven simulation algorithm and data structures. The overhead components of the optimistic algorithm as well as a number of optimization

A Trace-Driven Analysis of the UNIX 4.2 BSD File System

by John Ousterhout, Herve Da Costa, David Harrison, John A. Kunze, Mike Kupfer, James G. Thompson , 1985
"... We analyzed the UNIX 4.2 BSD file system by recording userlevel activity in trace files and writing programs to analyze the traces. The tracer did not record individual read and write operations, yet still provided tight bounds on what information was accessed and when. The trace analysis shows that ..."

Incomplete Trace Data And Trace Driven Simulation

by J. Kelly Flanagan, Brent E. Nelson, James K. Archibald, Knut Grimsrud - Proc. of International Workshop on Modeling, Analysis, and Simulation of Computer and Telecommunication Systems , 1995
"... We illustrate the sensitivity of trace driven simulation results to the completeness of the input trace data. This is done by comparing cache simulation results obtained using traces similar to many found in the published literature with those obtained using a hardware monitor which we have develope ..."

Analysis, Modeling and Generation of Self-Similar VBR Video Traffic

by Mark Garrett, Walter Willinger , 1994
"... We present a detailed statistical analysis of a 2-hour long empirical sample of VBR video. The sample was obtained by applying a simple intraframe video compression code to an action movie. The main findings of our analysis are (1) the tail behavior of the marginal bandwidth distribution can be accu ..."

for VBR video and present an algorithm for generating synthetic traffic. Trace-driven simulations show that statistical multiplexing results in significant bandwidth efficiency even when long-range dependence is present. Simulations of our source model show long-range dependence and heavy-tailed marginals

Large steps in cloth simulation

by David Baraff, Andrew Witkin - SIGGRAPH 98 Conference Proceedings , 1998
"... The bottle-neck in most cloth simulation systems is that time steps must be small to avoid numerical instability. This paper describes a cloth simulation system that can stably take large time steps. The simulation system couples a new technique for enforcing constraints on individual cloth particle ..."

Cost-Aware WWW Proxy Caching Algorithms

by Pei Cao, Sandy Irani - IN PROCEEDINGS OF THE 1997 USENIX SYMPOSIUM ON INTERNET TECHNOLOGY AND SYSTEMS , 1997
"... Web caches can not only reduce network traffic and downloading latency, but can also affect the distribution of web traffic over the network through costaware caching. This paper introduces GreedyDualSize, which incorporates locality with cost and size concerns in a simple and non-parameterized fash ..."
Abstract - Cited by 540 (6 self) - Add to MetaCart
-parameterized fashion for high performance. Trace-driven simulations show that with the appropriate cost definition, GreedyDual-Size outperforms existing web cache replacement algorithms in many aspects, including hit ratios, latency reduction and network cost reduction. In addition, GreedyDual-Size can potentially

Summary cache: A scalable wide-area web cache sharing protocol

by Li Fan, Pei Cao, Jussara Almeida, Andrei Z. Broder , 1998
"... The sharing of caches among Web proxies is an important technique to reduce Web traffic and alleviate network bottlenecks. Nevertheless it is not widely deployed due to the overhead of existing protocols. In this paper we propose a new protocol called "Summary Cache"; each proxy keeps a su ..."

entry. Using trace-driven simulations and a prototype implementation, we show that compared to the existing Internet Cache Protocol (ICP), Summary Cache reduces the number of inter-cache messages by a factor of 25 to 60, reduces the bandwidth consumption by over 50%, and eliminates between 30 % to 95

Analysis of TCP Performance over Mobile Ad Hoc Networks Part I: Problem Discussion and Analysis of Results

by Gavin Holland, Nitin Vaidya , 1999
"... Mobile ad hoc networks have gained a lot of attention lately as a means of providing continuous network connectivity to mobile computing devices regardless of physical location. Recently, a large amount of research has focused on the routing protocols needed in such an environment. In this two-part ..."
