Semi-partitioned Mixed-Criticality Scheduling [PDF]
, 2017 Scheduling isolation in mixed-criticality systems is challenging without sacrificing performance. In response, we propose a scheduling approach that combines server-based semi-partitioning and deadline-scaling. Semi-partitioning (whereby only some tasks migrate, in a carefully managed manner), hitherto used in single criticality systems, offers good ...

Intractability Issues in Mixed-Criticality Scheduling. [PDF]
, 2018 In seeking to develop mixed-criticality scheduling algorithms, one encounters challenges arising from two sources. First, mixed-criticality scheduling is an inherently an on-line problem in that scheduling decisions must be made without access to all the information that is needed to make such decisions optimally - such information is only revealed ...

Mixed-Criticality Scheduling with Dynamic Memory Bandwidth Regulation [PDF]
2018 IEEE 24th International Conference on Embedded and Real-Time Computing Systems and Applications (RTCSA), 2018 Mixed-criticality multicore system design must often guarantee both safety and high performance. Memory bandwidth regulation among different cores can be a useful tool for guaranteeing safety, as it mitigates the interference when accessing main memory.

Mixed-Criticality Scheduling of Sporadic Task Systems [PDF]
, 2011 We consider the scheduling of mixed-criticality task systems, that is, systems where each task to be scheduled has multiple levels of worst-case execution time estimates. We design a scheduling algorithm, EDF-VD, whose effectiveness we analyze using the processor speedup metric: we show that any 2-level task system that is schedulable on a unit-speed ...

Semi-Clairvoyance in Mixed-Criticality Scheduling [PDF]
2019 IEEE Real-Time Systems Symposium (RTSS), 2019 In the Vestal model of mixed-criticality systems, jobs are characterized by multiple different estimates of their actual, but unknown, worst-case execution time (WCET) parameters. Prior work on mixed-criticality scheduling theory assumes that the execution duration of a job is only revealed by actually executing the job through to completion.

Compensating Adaptive Mixed Criticality Scheduling [PDF]
Proceedings of the 30th International Conference on Real-Time Networks and Systems, 2022 The majority of prior academic research into mixed criticality systems assumes that if high-criticality tasks continue to execute beyond the execution time limits at which they would normally finish, then further workload due to low-criticality tasks may

Performance-Based Scheduling in Distributed Mixed Criticality Systems
IEEE AccessWith a focus on computationally intensive, distributed, and parallel workloads, scheduling in mixed-criticality distributed systems presents significant challenges due to shared memory and resources, as well as the diverse demands of tasks.
