| Fractal Analysis of Resource Exhaustion in Real Time Operating Systems | |

| Dates | October 2000 - December 2004 |
| Problem | Recent studies revealed the phenomenon of "software aging" as a major cause of outages in computer systems. The phenomenon is primarily due to the exhaustion of operating system resources, data corruption etc. Our recent research showed that multifractal analysis provides an effective quantitative description of the phenomenon. However it still remains to be explored whether the techniques of fractal analysis can be used to forecast software ageing and prevent crashes. |
| Objective | Based on our previous results, we conjecture that application of more advanced fractal analysis techniques to the system's resource dynamic will allow to estimate system outage hazard. We plan to develop an automated alarm system, which monitors the fractal dynamic of some of the operating system's resources and advices for graceful system shut-down when the probability of impending system failure is high. |
