| Abstract | The development of real-time distributed systems has always been a complex, platform-specific and expensive task. The introduction of the fork-join paradigm in multicore systems allowed the distribution of computations between the cores.This work proves that it is possible to implement the fork/join parallel computing paragidm in real-time systems. This paradigm allows to relocate part of the computation to different computational nodes when it is not feasible to execute the computation locally within a given deadline. Another motivation to distribute the computation can be the need to save energy on some battery-powered nodes by means of load balancing. The framework was developed with a focus on embedded nodes with low computational capabilities, and the implementation features a great deal of low-level optimization, with the goal of meeting deadlines up to 70 ms.The work was based on an open-source implementation of the communication protocol Flexible Time Trigger-Switched Ethernet (FTT-SE), in which the distributed operations are executed in Linux nodes equipped with the real-time scheduler provided by the kernel patch PREEMPT-RT.
