However, the resulting interleaving and memory interference make real-time guarantees of safety critical systems hard to be delivered. Beside to safety requirements, energy consumption represents a strong constraint for the deployment of such systems as they operate on energy-limited sources. Dynamic Voltage and Frequency Scaling (DVFS) was introduced as a technology to reduce the energy consumption of systems by tuning the frequency of processing cores according to the workload. One way of improving schedulability could be by running all cores with maximum frequency. Nevertheless, it has been proved in the literature that this solution is not optimal because it drains the battery energy and leads to eternal bottleneck as the number of memory requests increases linearly with the cores frequency. In this paper, we introduce a framework for fine grained specification and formal analysis of the schedulability and performance of DVFS-multicore systems having a hierarchy of shared memories. We design a collaborative scheduling algorithm to reduce the energy consumption and improve cores utilization. Our collaborative scheduling technique drives the scheduling of a core according to the adopted policy and the resulting memory interference. To that end, our framework provides the ability to run other ready tasks, when the current running tasks fall in a dense memory interference queue, rather than stalling on the memory interference.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123672845","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}

These systems are distributed real-time systems, and their simulations might be distributed or not. In this paper, we propose a model to describe the modular components forming a simulation of a CPS. The main goal is to introduce a model of generic simulation distributed architecture, on which we are able to execute a logical architecture of simulation. This architecture of simulation allows the expression of structural and behavioural constraints on the simulation, abstracting its execution. We will propose two implementations of the execution architecture based on generic architectures of distributed simulation: The High Level Architecture (HLA), an IEEE standard for distributed simulation, and one of its open-source implementation of RunTime Infrastructure (RTI): CERTI. The Distributed Simulation Scheduler (DSS), an Airbus framework scheduling predefined models. Finally, we present the initial results obtained applying our formalism to the open-source case study from the ROSACE case study.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126441262","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}

There are many challenges to tackle such as managing distributed resources, enabling communication between components, and choosing performance metrics to evaluate the “goodness” of the system. Smart Grids (SGs) are prominent representatives of CPSs, a particular type of Critical Infrastructure (CI), whose organizational model is becoming more distributed and dynamic. Due to this paradigm shift, new control and management mechanisms need to be identified and tested to guarantee uninterrupted operation. However, novel approaches cannot always be tested against real networks as the economic cost and risk can be high. In contrast, modeling and simulation techniques are viable evaluation mechanisms that support the continuous evolution of CIs. In this paper, we present an Open Source time-discrete simulation software, called HOLEG, that models and evaluates SGs. The software is based on the Holon analogy, a bio-inspired approach that enables systems resilience through flexible reconfiguration mechanisms. The presented software provides features that enable the integration and execution of optimization algorithms along with their evaluation. To demonstrate HOLEG, a case study is presented where a heuristic algorithm is implemented to minimize wasted energy while preventing network destabilization.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116484046","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}

By relying on this computing organization, it is possible to effectively overcome both the power and the memory wall, which are core limiting aspects to deliver high-performance simulations. This is even more the case when relying on the speculative Time Warp synchronization protocol, which could be particularly memory greedy. At the same time, some form of coordination, such as the computation of the Global Virtual Time (GVT), is required by Time Warp Systems. These coordination points could easily become the bottleneck of large-scale simulations, hindering an efficient exploitation of the computing power offered by large supercomputing facilities. In this paper we present ORCHESTRA, a coordination algorithm which is both wait-free and asynchronous. The nature of this algorithm allows any computing node to carry on simulation activities while the global agreement is reached, thus offering an effective building block to achieve scalable PDES. We claim that the general organization of ORCHESTRA could be adopted by different high-performance computing applications, thus paving the way to a more effective usage of modern computing infrastructures.","PeriodicalId":109971,"journal":{"name":"2017 IEEE/ACM 21st International Symposium on Distributed Simulation and Real Time Applications (DS-RT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126620445","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}
