Traditional simulation, however, is based on an event-driven approach, which focuses on single sensor events and models within a single human activity. It requires detailed description and processing of every low-level event that enters into an activity scenario. For many realistic and complex human scenarios, the event-driven approach burdens the simulator users with complicated low-level specifications required to configure and run the simulation. It also increases computational complexity and impedes scalable simulation. Thus, we propose a novel, context-driven approach to simulating human activities in smart spaces. In the proposed approach, vectors of sensors rather than single sensor events drive the simulation quicker from one context to another. Abstracting the space state into contexts highly simplifies the tasks and efforts of the simulation user in setting up and configuring the simulation components for smart space and human activities. We present the context-driven simulation approach and show how it works. Then we present fundamental concepts and algorithms and provide a comparative performance study between the event- and context-driven simulation approaches.","PeriodicalId":115341,"journal":{"name":"Proceedings of the 1st ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129878590","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}

This poses a challenging problem for distributed simulation as it now becomes necessary to extend the algorithms to operate on a platform that includes both shared memory and distributed memory hardware. Furthermore, as the number of on-chip cores grows, the challenges for developing solutions without significant contention for shared data structures grows. This is especially true for the pending event list data structures where multiple execution threads attempt to schedule the next event for execution. This problem is especially aggravated in parallel simulation, where event executions are generally fine-grained leading quickly to non-trivial contention for the pending event list. This manuscript explores the design of the software architecture and several data structures to manage the pending event sets for execution in a Time Warp synchronized parallel simulation engine. The experiments are especially targeting multi-core and many-core Beowulf clusters containing 8-core to 48-core processors. These studies include a two-level structure for holding the pending event sets using three different data structures, namely: splay trees, the STL multiset, and ladder queues. Performance comparisons of the three data structures using two architectures for the pending event sets are presented.","PeriodicalId":115341,"journal":{"name":"Proceedings of the 1st ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132011513","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}

We describe SONSim, an approach to predict the execution time based on a simulation of an envisioned distributed network simulation (second-order simulation). SONSim takes into account both network model characteristics and hardware properties of the simulation execution environment. To show that a SONSim prototype is able to predict distributed performance with acceptable accuracy, we study three reference network simulation models differing fundamentally in topology and levels of model detail - simple topologies comprised of interconnected subnetworks, peer-to-peer networks and wireless networks. We evaluate the performance predictions for multiple configurations by comparing predictions for the three reference network models to execution time measurements of distributed simulations on physical hardware using both Ethernet and InfiniBand interconnects. In addition, utilizing the freedom to vary simulation hardware and model parameters in the second-order simulation, we demonstrate how SONSim can be used to identify general model characteristics that determine distributed simulation performance.","PeriodicalId":115341,"journal":{"name":"Proceedings of the 1st ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131025313","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}
