A hybrid fault injection environment for measuring system dependability

This thesis describes a test environment for evaluating computer system dependability, wherein faults are injected via software and the impact is measured by both software and hardware. The hybrid nature of the environment provides advantages in that it introduces minimal perturbation and provides a high degree of control over the location of faults to be injected. With this environment, faults can be injected into any location that has a physical address, e.g., CPU registers, cache, local memory, mass storage, and network controllers. Faults can also be injected into locations allocated to a single, executing user program or even into the kernel, and propagation can be characterized down to the instruction level. The environment is well suited for measuring extremely short error latencies. We illustrate the environment by applying it to the study of two commercial systems: A Unix-based, Tandem Integrity system and a Texas Instruments Explorer II Lisp machine.
