Further Analysis of a Computing Center Environment Empirical distributions of program lengths, execution times, processing times, and loading times of over 10,000 jobs serviced in a university computing center environment are presented. The data are subdivided according to certain characteristics of users and jobs to obtain selected empirical conditional distributions of those time properties as well as statistical measures of other interesting properties. The results are interpreted in terms of the properties of the system studied. CACM May, 1967 Walter, E. S. Wallace, V. L.
