Real-time virtualization is currently a hot topic, and there is much ongoing research on real-time Virtual Machines and hypervisors. However, most of the previous research focused either on reducing the latencies introduced by the virtualization ...

Cloud environments are becoming increasingly interesting to host time-critical use cases with far more stringent latency requirements than conventional cloud-native applications, such as smart industrial control systems or cloud-enabled autonomous ...

Real-time virtualization is currently a hot topic, and there is much ongoing research on real-time Virtual Machines and hypervisors. However, most of the previous research focused on the virtualization stack (hypervisor, host Operating System, ...

Modern real-time virtual machines and containers are starting to make it possible to support the execution of real-time applications in virtualized environments. Real-time scheduling theory already provides techniques for analyzing the ...

This paper shows how to use a Linux-based operating system as a real-time processing platform for low-latency and predictable packet processing in cloudified radio-access network (cRAN) scenarios. This use-case exhibits challenging end-to-end ...

This paper presents RT-Kubernetes, a software architecture with the ability to deploy real-time software components within containers in cloud infrastructures. The deployment of containers with guaranteed CPU scheduling is obtained by using a ...

This paper tackles the problem of admitting real-time tasks on non-symmetric multiprocessor platforms, where partitioned EDF-FF is used. We extend the already obtained results for symmetric multiprocessor platforms and provide an ...

This paper introduces a novel admission test for partitioned CBS reservations on multi-core systems, that, on a new reservation arrival, is capable of exploiting better the CPU capacity in cases in which tasks have just recently left the CPU (for ...

SCHED_DEADLINE (DL for short) is an Earliest-Deadline-First (EDF) scheduler included in the Linux kernel. A question motivated by DL is how EDF should be implemented in the presence of CPU affinities to maintain optimal bounded tardiness guarantees. ...

This paper presents a novel migration algorithm for real-time tasks on multicore systems, based on the idea of migrating tasks only when strictly needed to respect their temporal constraints and a combination of this new algorithm with EDF scheduling. ...

Real-time languages found in the literature, starting with Esterel up to Timed C, cannot be compiled using off-the-shelf C++ compilers and processed by off-the-shelf C++ tools (e.g., editors, debuggers, program analyzers). Since C++ is one of the de ...

This paper presents a new algorithm for scheduling real-time tasks on multiprocessor/multicore systems. This new algorithm is based on combining EDF scheduling with a migration strategy that moves tasks only when needed. It has been evaluated through an ...

General-purpose programming languages C and C++ address only the functional aspect of programs. In contrast, real-time programming languages address not only the functional aspect but also the nonfunctional real-time aspect to automatically ensure the ...

In recent years, there has been a growing interest in supporting component-based software development of complex real-time embedded systems. Techniques such as machine virtualisation have emerged as interesting mechanisms to enhance the security of ...

In this paper, we perform a comparison among a number of different virtual bridging and switching technologies, each widely available and commonly used on Linux, to provide network connectivity to co-located LXC containers for high-performance ...

• Problem: timely & energy-efficient execution of low-latency audio applications.

Counting more than two billion devices, Android is nowadays one of the most popular open-source general-purpose operating systems, based on Linux. Because of the diversity of applications that can be installed, it manages a number of ...

The recent changes made in the Linux kernel aimed at achieving better energy efficiency through a tighter integration between the CPU scheduler and the frequency-scaling subsystem. However, in the original implementation, the frequency scaling mechanism ...

The recent changes made in the Linux kernel aim at achieving better energy efficiency through a tighter integration between the CPU scheduler and the frequency-scaling subsystem. However, in the current implementation, the frequency scaling mechanism is ...

The Hard Constant Bandwidth Server (H-CBS) is a reservation-based scheduling algorithm often used to mix hard and soft real-time tasks on the same system. A number of variants of the H-CBS algorithm have been proposed in the last years, but all of them ...

This paper presents a new strategy for scheduling soft real-time tasks on multiple identical cores. The proposed approach is based on partitioned CPU reservations and it uses a reclaiming mechanism to reduce the number of missed deadlines. We introduce ...
