The purpose of this workshop is to discuss the problems and general needs of real-time application developers and propose a minimum subset of operating system services that would be appropriate to satisfy the majority of the new timing, QoS, and composability requirements that applications have today, with the objective of
evolving from the rather static scheduling present in today's RTOSs, primarily based on off-line scheduling techniques, towards more flexible and dynamic approaches.
