A Fault-tolerant Real-time Scheduling Algorithm for Precedence-Constrained Tasks in Distributed Heterogeneous Systems

Real-time Fault-tolerant Scheduling Algorithm for Distributed Computing Systems

This article proposes a Distributed Realtime Fault-tolerant model, priority Real-time Fault-tolerant algorithm and computational architecture of Distributed Real-time Fault-tolerant. According to this model, the problem of how to schedule a weighted Directed Acyclic Graph (DAG) in Distributed computing system for high reliability can be solved in the presence of multiprocessors faults. When som...

Towards a Contract-based Fault-tolerant Scheduling Framework for Distributed Real-time Systems

The increasing complexity of real-time systems has lead to the adaptation of component based methods for their development which has a promising potential for faster and more cost effective development of complex real-time systems by facilitating reuse of the real-time components. This is enabled by the components’ composition using contracts, which ensures ’correctness by construction’. Modern...

Communication-aware Fault-tolerant Scheduling Strategy for Precedence Constrained Tasks in Heterogeneous Distributed Systems

Abstract Fault-tolerant scheduling is an important issue for optimal heterogeneous distributed systems because of a wide range of resource failures. Primary-backup approach is a common methodology used for fault tolerance wherein each task has a primary copy and a backup copy on two different processors. For independent tasks, the backup copy can overload with other backup copies on the same pr...

Reliability-Driven Fault Tolerant Scheduling Heuristics for Distributed Embedded Real-Time Systems

We present a new scheduling approach to produce automatically a fault tolerant distributed schedule for critical distributed and real-time embedded systems. The approach that we propose take as input a set of operations (tasks), a target distributed architecture, some distribution constraints, some indications on the execution times of the operations on the processors of the target architecture...
