Abstract

Recent research has demonstrated the existence of locality in short-term file referencing behaviour. A detailed study of the dynamic characteristics of file referencing is presented in this paper. The concept of Bounded Locality Intervals from the field of program behaviour has been used to model the locality phases of file referencing behaviour. The model is found to be powerful both from a descriptive point of view and from the perspective of understanding the performance implications of locality properties of file referencing behaviour on file system management.
