Comparing fault susceptibility of multiple ISAs and operating systems

This paper presents a novel research that aims to compare effects of faults on different configurations of computer systems. A software implemented fault injection technique based on emulation was introduced. The study covers comparison of susceptibility to faults of multiple architectures and operating systems. The problem of choosing an adequate number of tests in experiments is followed by report with collected results where multiple aspects of test runs were analyzed: providing correct computation result, availability of the system under test and error messages. The research allows to determine characteristics of susceptibility to faults of each platform and is a first step towards designing new fault tolerance solutions and assessing their effectiveness.
