Recently, there has been interest in developing a dependability benchmarks for computer systems. This will require a way to inject several different types of faults into many different platforms and a way to collect and compare the results. Analyzing complex heterogeneous distributed systems share the same needs. The current approach to building fault injection tool is inappropriate for these g...

Fault injection is a widely used technique to test the robustness of software systems and to find bugs in applications. We focus on using fault injection to judge the quality of error handling in applications. Even mature applications have serious bugs in error handling [3]. To find all bugs related to bad error handling when using a certain API one has to do exhaustive fault injection, i.e., t...

abstract - one of the important problems in grid environments is data replication in grid sites. reliability and availability of data replication in some cases is considered low. to separate sites with high reliability and high availability of sites with low availability and low reliability, clustering can be used. in this study, the data grid dynamically evaluate and predict the condition of t...

This paper describes a dependability evaluation method based on fault injection that establishes the link between the experimental evaluation of the fault tolerance process and the fault occurrence process. The main characteristics of a fault injection test sequence aimed at evaluating the coverage of the fault tolerance process are presented. Emphasis is given to the derivation of experimental...

Fault injection provides a method of assessing the dependability of a system under test. Traditionally fault injection is employed near the end of the design process after hardware and software prototypes have been developed. In order to eliminate costly re-designs near the end of the design process, a methodology for performing fault injection throughout the design process is described in this...

Three different VHDL-based fault injection techniques have been compared to validate a fault tolerant microcomputer system. We have studied the error pathology, their detection and recovery coverages and their latencies.

This paper focuses on the integration of the fault injection methodology within the design process of fault-tolerant systems. Due to its wide spectrum of application and hierarchical features, VHDL has been selected as the simulation language to support such an integration. Suitable techniques for injecting faults into VHDL models are identified and depicted. Then, the main features of the MEFI...

Fault injection is an important technique for the evaluation of design metrics such as reliability, safety, and fault coverage. Fault injection involves inserting faults into a system and monitoring the system to determine its behavior in response to the fault. Recently, designers are realizing the advantages of using simulation to perform fault injection on a model of the design, as opposed to...
