Thread Carefully: Preventing Starvation in the ROS 2 Multithreaded Executor

color access or modify the same resource, such as a mutex, a variable, or a data structure (excluding the wait set). Uncolored boxes indicate the operation is not resource specific. The parallelograms represent [...] in the wait set are then executed in the related processing window. The goal is to utilize the resources of the system whenever there are eligible tasks. As the ROS 2 system is hosted by an operating system [...] the wait set is shared among all the threads of an executor. Hence, ROS 2 uses multiple shared resources to ensure the data consistency in the wait set. A. Processing Windows We first explain how the task …
