Measurement of File Operating Effectiveness. Final Report.
The report summarizes work done in the study of measures for the effectiveness of the performance of large file systems. It consists of six sections: An "Introduction and Summary" which describes the background for the study, the approach taken in it, and summarizes the results; A discussion of the "Forms of Input", which characterizes the basic issues in representing complex phenomena in a form to be processed; An analysis of the lattice model of vocabulary structure and development of methodologies for vocabulary decomposition as a means of organizing formal representations; A characterization of the probabilities of file items in response to requests; The definition of a measure of file performance with emphasis on its relation to file organization in an environment of error and uncertainty; The presentation of a simulation by which the performance of large files can be exhibited and explored under different conditions.
