COSSIM: An open-source integrated solution to address the simulator gap for systems of systemsCOSSIM: An open-source integrated solution to address the simulator gap for systems of systems Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2019-05-312018enIn an era of complex networked heterogeneous systems, simulating independently only parts, components or attributes of a system under design is not a viable, accurate or efficient option. The interactions are too many and too complicated to produce meaningful results and the optimization opportunities are severely limited when considering each part of a system in an isolated manner. The presented COSSIM simulation framework is the first known open-source, high-performance simulator that can handle holistically system-of-systems including processors, peripherals and networks; such an approach is very appealing to both CPS/IoT and Highly Parallel Heterogeneous Systems designers and application developers. Our highly integrated approach is further augmented with accurate power estimation and security sub-tools that can tap on all system components and perform security and robustness analysis of the overall networked system. Additionally, a GUI has been developed to provide easy simulation set-up, execution and visualization of results. COSSIM has been evaluated using real-world applications representing cloud (mobile visual search) and CPS systems (building management) demonstrating high accuracy and performance that scales almost linearly with the number of CPUs dedicated to the simulator. http://creativecommons.org/licenses/by/4.0/115-12021st Euromicro Conference on Digital System DesignProceedings of 21st Euromicro Conference on Digital System Design Brokalakis Andreas Μπροκαλακης Ανδρεας Tampouratzis Nikolaos Ταμπουρατζης Νικολαος Nikitakis Antonios Νικητακης Αντωνιος Papaefstathiou Ioannis Παπαευσταθιου Ιωαννης Andrianakis Stamatios Ανδριανακης Σταματιος Pau Danilo Plebani Emanuele Paracchini Marco Marcon Marco Sourdis Ioannis Geethakumari Prajith Ramakrishnan Palacios Maria Carmen Anton Miguel Angel Szasz Attila Institute of Electrical and Electronics Engineers Cps simulator Distributed system simulator Gem5 High level architecture Omnet++ Parallel system simulator
