An Efficient Fault-Tolerant Multi-Bus Data Scheduling Algorithm Based on Replication and Deallocation

Abstract

Single-phase Pr 2 CBr was prepared by heating a mixture of PrBr 3 , Pr and C (1 : 5:3) to 1140 • C for 18 d. The crystal structure was investigated by X-ray single crystal diffraction (space group P6 3 /mmc, a = 3.8071 (3), c = 14.7787(12)Å). In the structure the Pr atoms form C-centered octahedra condensed into Pr 2 C sheets via common edges; these sheets are separated by the Br atoms which are in a trigonal prismatic environment of Pr atoms. Pr 2 CBr is a black shiny compound with metallic conductivity. It is a ferromagnet with T c = 13.8(5) K.

An Efficient Fault-Tolerant Scheduling Approach with Energy Minimization for Hard Real-Time Embedded Systems

“…With active replication, all the task replicas are executed independent of fault occurrences [25]. However, with passive replication, backup replicas are executed only if the primary replica is faulty [29,30].…”

A Fault Tolerant Scheduling Heuristics for Distributed Real Time Embedded Systems

“…A large number of fault tolerant scheduling algorithms for real-time embedded systems have been proposed in the literature. In [11], authors use software redundancy solutions based on both active and passive backup copies to tolerate only one bus fault in multi-bus heterogeneous architectures. In [12], they overcome the faults in the sensor network and distribute the provided task rationally by using a technique called P/B, it uses passive backup copies overlapping methodology to monitor the mode of backup copies adaptively through scheduling primary copies early and backup copies delayed.…”
