Scalable Fault Tolerance in Multiprocessor Systems
Evolving trends in design and use of computers are resulting in fault-prone systems which may not execute a program to completion. Checkpoint-and-recovery is commonly used to recover from faults and complete parallel programs. Conventional checkpointing-and-recovery can incur high overheads and may be inadequate in the future as faults become frequent. We propose to execute parallel programs de...
متن کاملAdaptable Fault Tolerance Configurations for Multiprocessor Systems
The escalating increase in the complexity of multiprocessor systems increases the probability of faults occurring in these systems As a consequence there is a great need for achieving fault-tolerance of processing in multiprocessor systems. Faulttolerance generally requires some forms of hardware and/or time redundancy. Two fault tolerant configurations are proposed for both single and double t...
متن کاملFault Tolerance for Multiprocessor Systems Via Time Redundant Task Scheduling
Fault tolerance is often considered as a good additional feature for multiprocessor systems but nowadays it is becoming an essential attribute. Fault tolerance can be achieved by the use of dedicated customized hardware that may have the disadvantage of large cost. Another approach to fault tolerance is to exploit existing redundancy in multiprocessor systems via a task scheduling software stra...
متن کاملFault Tolerance via Endocrinologic Based Communication for Multiprocessor Systems
The communication mechanism used by the biological cells of higher animals is an integral part of an organisms ability to tolerate cell deficiency or loss. The massive redundancy found at the cellular level is fully taken advantage of by the biological endocrinologic processes. Endocrinology, the study of intercellular communication, involves the mediation of chemical messengers called hormones...
متن کاملA Fault-Tolerance Model for Multiprocessor Real-Time Systems
System reliability is an important aspect of real-time systems, because the result of a real-time application may be valid only if the application functions correctly and its timing constraints are satisfied. There are two kinds of faults, hardware and software faults, and the paper considers hardware transient faults. Full replication or full hardware redundancy can achieve a high degree of re...
