The network is being designed by identifying simulation tasks which may be performed in parallel with other computation required by the simulation, and then assigning those subtasks to attached processing elements in the network. The tasks of priority queue processing and state accounting are considered in this paper. A three attached processor simulation computer has been designed, using two processors for the event set and the third for state statistics accumulation. In a simulation model of this system, a forty to fifty percent reduction in the execution of a benchmark simulation program is easily achieved. (The benchmark program itself uses an adaptive scheduling algorithm). Further observations and suggestions for future research are presented.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123986867","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}

The performance degradation caused by contention among computers is therefore becoming more acute. The problem will be even more serious when a network of distributed microcomputers is to operate the real-time simulators. In an effort to estimate the contention degradation apriori, a recursive relationship linking the effective worth of a multiprocessor structure consisting of k+1 processors to that of k processors has been obtained. The computational results have been favorably compared to the measured values. The relationship has since been used to help select most cost-effective computer systems for real-time simulators.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130743815","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}

Graphical representations of the model structure and of simulation output help to make models transparent to the user.
