High-availability computer systems - Computer
September 1991 aradoxically, the larger a system is, the more critical but less likely it is to be highly available. We can build small ultra-available modules, but building large systems involving thousands of modules and millions of lines of code is a poorly understood art, even though such large systems are a core technology of modern society. Three decades ago, hardware components were the ...
متن کاملSequential Experiment Design for Contour Estimation From Complex Computer Codes
Computer simulation is often used to study complex physical and engineering processes. While a computer simulator can often be viewed as an inexpensive way to gain insight into a system, it can still be computationally costly. Much of the recent work on the design and analysis of computer experiments has focused on scenarios where the goal is to fit a response surface or process optimization. I...
متن کاملMonte Carlo Simulation of Computer System Availability/Reliability Models
In recent years, there has been an increased interest in evaluating the availability and reliability of computer systems. For this purpose, we have developed a state of the art modeling package called SAVE (System Availability Estimator). This package has refined numerical matrix methods for computing the dependability measures of interest. These methods do, however, have their limitations sinc...
متن کاملSequential Estimation of Quantiles
Quantiles are convenient measures of the entire range of values of simulation outputs. However, unlike the mean and standard deviation, the observations have to be stored since calculation of quantiles requires several passes through the data. Thus, quantile estimation(QE) requires a large amount of computer storage and computation time. Several approaches for estimating quantiles in RS(regener...
متن کاملSystem Availability
Increasing MTTF requires increasing reliability. In previous lectures we saw a variety of ways to do so: testing, static analysis, formal methods, etc. A highly reliable system is a highly available system. Reducing MTTR requires reducing the (mean) time it takes for the system to come back up once a failure has occurred. Once a failure occurs, we must detect it, diagnose it, and the recover th...
