However, some embedded real-time systems but also useful for the simulation and applications also have tasks with arbitrary deadlines, i.e., for validation of those systems. During the evaluation of our paper some tasks D > T . If the tasks are strictly periodic, this about Systems with Dynamic Real-Time Guarantees that appears i i in RTSS 2016 we discovered certain unexpected system behavior leads to a situation where two or more instances of the same in the open-source real-time operating system RTEMS.
