  2. 16. The Impact of Application and Architecture Properties on Real-Time Multiprocessor Scheduling

    Author : Jan Jonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; real-time scheduling; multiprocessor architectures; architecture properties; application properties; performance evaluation; predictability;

    Abstract : Guaranteeing the temporal correctness of a real-time system is a very challenging problem since application and architecture properties may be hard to model accurately. For example, modern computer architectures are typically equipped with mechanisms, such as cache memories and instruction pipelines, whose behavior are by nature stochastic. READ MORE

  4. 17. Optimizing Fault Tolerance for Real-Time Systems

    Author : Dimitar Nikolov; Erik Larsson; Elena A. Troubitsyna; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : For the vast majority of computer systems correct operation is defined as producing the correct result within a time constraint (deadline). We refer to such computer systems as real-time systems (RTSs). READ MORE

  5. 18. Limited Preemptive Scheduling in Real-time Systems

    Author : Abhilash Thekkilakattil; Sasikumar Punnekkat; Radu Dobrin; Reinder Bril; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Preemptive and non-preemptive scheduling paradigms typically introduce undesirable side effects when scheduling real-time tasks, mainly in the form of preemption overheads and blocking, that potentially compromise timeliness guarantees. The high preemption overheads in preemptive real-time scheduling may imply high resource utilization, often requiring significant over-provisioning, e. READ MORE

  6. 19. Adaptive Resource Management for Uncertain Execution Platforms

    Author : Mikael Lindberg; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Embedded systems are becoming increasingly complex. At the same time, the components that make up the system grow more uncertain in their properties. For example, current developments in CPU design focuses on optimizing for average performance rather than better worst case performance. READ MORE

  7. 20. Fault Tolerance for Real-Time Systems: Analysis and Optimization of Roll-back Recovery with Checkpointing

    Author : Dimitar Nikolov; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft errors; fault tolerance; real-time systems; checkpointing; reliability;

    Abstract : Increasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. READ MORE
