Promising Parallel Discrete Event Simulation (PDES) approaches with optimistic and conservative synchronisation schemes have emerged throughout the years. However, in the area of real-time simulation, PDESs are rarely considered. This is caused by the complex problem of fitting parallel executed DES models to a real-time clock. Hence, this paper gives an extensive review of existing conservative and optimistic synchronisation schemes for PDESs. It introduces a metric to compare their real-time capabilities to determine whether they can be used for soft or firm real-time simulation. Examples are given on how to apply this metric to evaluate PDESs using synthetic and real-world examples. The results of the investigation reveal that no final answer can be given if PDESs can be used for soft or firm real-time simulation as they are. However, boundary conditions were defined, which allow a use-case specific evaluation of the real-time capabilities of a certain parallel executed DES. Using this in-depth knowledge and can lead to predictability of the real-time behaviour of a simulation run.}, language = {en} } @inproceedings{ObermaierRieblFacchietal.2021, author = {Obermaier, Christina and Riebl, Raphael and Facchi, Christian and Al-Bayatti, Ali H. and Khan, Sarmadullah}, title = {COSIDIA: an approach for real-time parallel discrete event simulations tailored for wireless networks}, booktitle = {SIGSIM-PADS '21: Proceedings of the 2021 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation}, publisher = {ACM}, address = {New York}, isbn = {978-1-4503-8296-0}, doi = {https://doi.org/10.1145/3437959.3459250}, pages = {165 -- 171}, year = {2021}, language = {en} } @inproceedings{ObermaierRieblAlBayattietal.2019, author = {Obermaier, Christina and Riebl, Raphael and Al-Bayatti, Ali H. and Facchi, Christian and Khan, Sarmadullah}, title = {Limitations of HIL Test Architectures for Car2X Communication Devices and Applications}, booktitle = {Proceedings CSCS 2019: ACM Computer Science in Cars Symposium}, publisher = {ACM}, address = {New York}, isbn = {978-1-4503-7004-2}, doi = {https://doi.org/10.1145/3359999.3360493}, year = {2019}, language = {en} }
