Two specific implementations are described, one for client/server work and the other a distributed, parallel simulator using conservative synchronisation protocols.

Efficiency is defined as the ability to reduce the amount of pairwise comparisons needed to completely execute the intended system. Sectoring involves partitioning the simulation trajectory space and allows for a reduction of the number of queries required between objects in order to determine upcoming events. However, the crossing of sector boundaries becomes an additional event to track and compute. A simulation of moving objects in 3-D space was constructed using MODSIM™. This simulation was verified and used to gather significant output data. The results indicated that, within the specific experimental range, sectoring provides up to 52% improvement in simulation efficiency when compared to no sectoring.</p></div>","PeriodicalId":101162,"journal":{"name":"Simulation Practice and Theory","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0928-4869(01)00029-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80402097","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}
