Real-Time Containers: A Survey

Authors: Václav Struhár, Moris Behnam, Mohammad Ashjaei, and Alessandro V. Papadopoulos

Published in: OASIcs, Volume 80, 2nd Workshop on Fog Computing and the IoT (Fog-IoT 2020)

Abstract
Container-based virtualization has gained a significant importance in a deployment of software applications in cloud-based environments. The technology fully relies on operating system features and does not require a virtualization layer (hypervisor) that introduces a performance degradation. Container-based virtualization allows to co-locate multiple isolated containers on a single computation node as well as to decompose an application into multiple containers distributed among several hosts (e.g., in fog computing layer). Such a technology seems very promising in other domains as well, e.g., in industrial automation, automotive, and aviation industry where mixed criticality containerized applications from various vendors can be co-located on shared resources. However, such industrial domains often require real-time behavior (i.e, a capability to meet predefined deadlines). These capabilities are not fully supported by the container-based virtualization yet. In this work, we provide a systematic literature survey study that summarizes the effort of the research community on bringing real-time properties in container-based virtualization. We categorize existing work into main research areas and identify possible immature points of the technology.

Per Processor Spin-Based Protocols for Multiprocessor Real-Time Systems

Authors: Sara Afshar, Moris Behnam, Reinder J. Bril, and Thomas Nolte

Published in: LITES, Volume 4, Issue 2 (2017). Leibniz Transactions on Embedded Systems, Volume 4, Issue 2

Abstract
This paper investigates preemptive spin-based global resource sharing protocols for resource-constrained real-time embedded multi-core systems based on partitioned fixed-priority preemptive scheduling. We present preemptive spin-based protocols that feature (i) an increased schedulability ratio of task sets and reduced response jitter of tasks compared to the classical non-preemptive spin-based protocol, (ii) similar memory requirements for the administration of waiting tasks as for the non-preemptive protocol whilst only causing (iii) a minimal increase of the minimal number of required stacks per core from one to at most two, and (iv) strong progress guarantees to tasks. We complement these protocols with a unified worst-case response time analysis that specializes to the classical analysis for the non-preemptive protocol. The paper includes a comparative evaluation of the preemptive protocols and the non-preemptive protocol based on synthetic data.
