Adaptive Checkpoint Interval Algorithm Considering Task Deadline and Lifetime Reliability for Real-Time System☆

TL;DR: In this paper , a communication-induced adaptive checkpointing fault-tolerant mechanism (CIAC-FTM) is proposed to address software faults at application level in IoT. This mechanism places checkpoints at required nodes depending on the type of fault detected, in turn reducing checkpoints and storage overheads.

TL;DR: In this paper , the authors propose the integration of a Request Replication mechanism in FaaS platforms and describe how this integration was implemented in Fission, a well-known, open-source platform.

Abstract: Check pointing mechanism is used to tolerate the impact of transient faults through roll-back operation to a previously saved system state. In this paper, we propose a novel check pointing mechanism that considers fault tolerance in a duplex system in the presence of both transient and permanent faults. The main objective of our proposed mechanism is to extend the lifetime reliability of the duplex system by avoiding or even tolerating permanent faults in microprocessors. In addition, we also propose to migrate tasks from a 'near-to-die' processor to a spare processor under a condition where the current Mean-Time-To-Failure (MTTF) value is less or equal to a pre-determined threshold MTTF value. We validate our proposed mechanism and perform overhead analysis using various case studies. Later, we compare it with one of the most popular existing check pointing mechanism, namely the roll-forward check pointing scheme [9]. We show that unlike roll-back or roll-forward mechanisms, our proposed mechanism gives significantly higher lifetime reliability with reasonable system overheads.

TL;DR: This book provides a comprehensive description of the architetural techniques to tackle the soft error problem, and covers the new methodologies for quantitative analysis of soft errors as well as novel, cost-effective architectural techniques to mitigate them.

TL;DR: An analytical model is proposed to estimate the lifetime reliability of multiprocessor platforms when executing periodical tasks, and a novel lifetime reliability-aware task allocation and scheduling algorithm based on simulated annealing technique is presented.

TL;DR: This paper presents and discusses two alternative roll-forward recovery schemes, especially for time-critical and interaction-intensive applications, that deliver correct, timely results even when checkpoint validation is required.

TL;DR: This paper aims at minimizing the energy consumption when executing a divisible workload under a bound on the total execution time, while resilience is provided through checkpointing, and proposes either an exact solution, or a function that can be optimized numerically.
