Workload-Based Estimation of Resource Exhaustion in Software Systems

چکیده
Several recent studies have reported the phenomenon of software aging, where the state of the system degrades with time due to exhaustion of operating system resources, data corruption and numerical error accumulation. This eventually leads to performance degradation or crash/hang failure of the software. In this paper, we propose a measurement-based performability model to estimate the rate of exhaustion of operating system resources as a function of time and the system workload state. With the help of this measure, pro-active fault management techniques such as software rejuvenation may be employed to prevent unexpected outages.

A measurement-based model for estimation of resource exhaustion in operational software systems
Software systems are known to suffer from outages due to transient errors. Recently, the phenomenon of ”software aging” [5, 10], one in which the state of the software system degrades with time, has been reported. The primary causes of this degradation are the exhaustion of operating system resources, data corruption and numerical error accumulation. This may eventually lead to performance degr...

متن کاملA Model-Driven Decision Support System for Software Cost Estimation (Case Study: Projects in NASA60 Dataset)
Estimating the costs of software development is one of the most important activities in software project management. Inaccuracies in such estimates may cause irreparable loss. A low estimate of the cost of projects will result in failure on delivery on time and indicates the inefficiency of the software development team. On the other hand, high estimates of resources and costs for a project wil...
