Efficient transaction scheduling algorithms are required to minimize the number of missed transaction deadlines.

The model is developed progressing from a simple mathematical analysis to complicated simulations.

The authors' simulation approach is based on a behavioral model for parallel programs. It is behavioral because it assumes the knowledge of the parallel program run-time behavior. A simulator maps (or 'executes') behavioral programs onto a multiprocessor system and produces a set of statistics used in performance evaluation. Preliminary experiments studied the effect of the task firing strategy on program performance. Systems with different characteristics have been investigated.<<ETX>>","PeriodicalId":215380,"journal":{"name":"Proceedings. 25th Annual Simulation Symposium","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132111462","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 authors examine a technique to reduce the number of items (i.e., events) to be scheduled by combining all the events to be processed by the same part of the simulation (referred to as a logical process) at the same simulation time. While fewer items need to be scheduled as a result of the formation of these event combinations in existing unified event set implementations, the scheduling must be done by both event time and the identity of the logical process which is to process the event. To address the complexity of this two-component priority, the authors introduce and examine several split event set implementations as schedulers. Empirical performance comparisons between unified and split implementations using closed queuing network and other simulations demonstrate the advantage of split implementations for large event sets.<<ETX>>","PeriodicalId":215380,"journal":{"name":"Proceedings. 25th Annual Simulation Symposium","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124475131","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, language support is needed to handle the complexities involved so that the underlying parallel mechanisms become transparent to the users. This paper presents a simulation environment called SIMA which addresses such issues. SIMA is an experimental environment for parallel discrete-event simulation in which a simulation model can be specified by the provided primitives and be executed on a shared memory multiprocessor. The parallel mechanisms of SIMA are totally transparent to users. This property makes usage of SIMA very convenient. Users can have the benefit of faster execution on a parallel computer without requiring knowledge about parallel processing. The base language is C and the interfaces are library routines and input arguments. The interfaces facilitate both parallel and sequential simulation. Several experiments indicate that SIMA has a satisfactory performance. Speedups of over 10 for many cases have been achieved using 15 processors.<<ETX>>","PeriodicalId":215380,"journal":{"name":"Proceedings. 25th Annual Simulation Symposium","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132564429","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}

Such models are however usually too large and complex to analyze and simulate using standard techniques. Originally the model symmetries inherent to the colour definitions of stochastic well-formed nets were exploited for Markovian analysis. The authors propose a similar technique to substantially reduce the average length of the event list in case of large and symmetric models. Examples of real simulation models of multiprocessor system architectures show that, after a given threshold, the symbolic simulation time may be virtually independent of the actual size of the system to be modelled, thus making the simulation of systems with thousand processors as inexpensive as the simulation of systems with only few processors.<<ETX>>","PeriodicalId":215380,"journal":{"name":"Proceedings. 25th Annual Simulation Symposium","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121396913","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}
