Simulation-based Performability Evaluation of Fault-tolerant Multiprocessors

چکیده
We present a case study of performance and dependability evaluation of fault-tolerant multiprocessors. A distributed shared-memory multiprocessor architecture providing faulttolerance is analyzed taking into account system functionalities, actual workloads, failures of system components as well as the inter-component dependences. Since the evaluation of such a complex system has to be performed already during the design phase, a simulation model has been developed and is being used to gain insight into the system behavior and to uncover weak points and bottlenecks. Object-oriented software design and process-oriented simulation techniques are used for the construction of a sophisticated simulation model.

Application-Dependent Performability Evaluation of Fault-Tolerant Multiprocessors
Abstract A case study of performance and dependability evaluation of fault-tolerant multiprocessors is presented. Two specific architectures are analyzed taking into account system functionality, actual workloads, failures of system components as well as the inter-component dependencies. Since the evaluation of such complex systems has to be performed already during the design phase, simulation...
متن کاملFault Injection Based Validation of Fault-Tolerant Multiprocessors
One of the most crucial tasks in the design of fault-tolerant computers is the validation of the builtin error detection and handling mechanisms. Predesign validation techniques, like performability modelling and analysis, often require such information as exact failure rates, which is usually unavailable for the user. Moreover, the majority of computer failures originate from transient faults,...

In this paper we discuss a unified approach towards model-based quantitative evaluation of both computer systems and communication systems. In the area of fault-tolerant computer systems, dependability evaluation has been recognized as being a topic of importance, both to judge a system on its merits and to provide trust in the actual dependability of the system. In communication systems, the n...

متن کاملPerformability of a token bus network under transient fault conditions
Local area networks are representative of a growing class of distributed systems which demand more sophisticated methods and tools to evaluate system behavior in the presence of faults. In particular, since they are likely to exhibit degradable performance, the concept of performability can provide more re ned assessments of their ability to perform under fault and error conditions. This paper ...
