If traditional simulation techniques are now widespread and well-understood by a large number of users, this is not the case for distributed simulation used only by a few researchers. The authors demonstrate that parallel and distributed simulation techniques can be used to simulate large and complex models of ATM networks for performance evaluation. The CSAM tool has been developed for that purpose. The test model consists of a large ATM network with a load-balanced routing scheme that relies on link cost functions to distribute the load.","PeriodicalId":339060,"journal":{"name":"Proceedings 31st Annual Simulation Symposium","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121672121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In spite of that, the cycle time of a simulation study is still long. The paper presents some remarks on model reduction reasoning and how, through this, the time of a simulation study could be reduced. The discussion is based on the example of Kienbaum and Paul (1994) of the pub problem, using a simplification of their H-ACD representation to describe the original and reduced models. The models are implemented and the results obtained shows their statistical equivalence which suggests the feasibility of this approach.","PeriodicalId":339060,"journal":{"name":"Proceedings 31st Annual Simulation Symposium","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132827237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the exploitation of parallel simulation technology in real-life applications has been hindered mainly by the lack of simulation support tools. The paper describes the design of SPaDES (Structured Parallel Discrete-Event Simulation), a parallel simulation environment for developing portable simulation models, and a platform for design experimentation of parallel simulation synchronization protocols. An implementation of the environment, SPaDES/C/sub ++/, cleanly separates simulation modeling and programming from the details of parallelization such as parallel simulation synchronization and parallel programming. For ease of portability and modular design, SPaDES/C/sub ++/ is implemented as a parallel simulation library. A comparison of SPaDES/C/sub ++/ with CSim and Simscript using two application examples is discussed.","PeriodicalId":339060,"journal":{"name":"Proceedings 31st Annual Simulation Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129996928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an event scheduling scheme, the virtual time window (VTW) protocol is applied. The virtual time window has influences not only on balancing the progress of logical processes, but also on adjusting the computation granularity between two consecutive interprocessor communications. The author investigates various performance aspects of the virtual time window protocol for parallel optimistic logic circuit simulation on a cluster of SUN Ultra workstations interconnected by a 100 Mbps Ethernet. With the goal of designing an adaptive optimistic synchronization protocol, the author measures and interprets the influence of the control parameter, i.e., the size of time window, on the various aspects of the simulation state, such as rollback and communication costs, which are related to the dynamic state of parallel logic circuit simulation. In addition, execution activity and simulation progress are considered.","PeriodicalId":339060,"journal":{"name":"Proceedings 31st Annual Simulation Symposium","volume":"415 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128808539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
