Abstract : Computer system operation can be adversely affected by physical disturbances emanating from a wide variety of sources. These disturbances, often transient in nature, are manifested in computer systems as upsets. An upset of a computer system is defined as a performance deviation that is based on a-priori operation knowledge of the computer system's task. The results of a computer system upset can be as obvious as a complete system crash or as intermittent computational errors. Hence, there exists a need to access computer system susceptability/resilience relative to transient disturbances with systematic experimentation. This paper will discuss general issues relevant to that experimentation. In a companion paper, some actual fault injection experimentation will be detailed relative to a particular microprocessor-based system. (Author)
