An analysis was made of the correlation between performance and resource usage variables of a given computer job and between the performance variables of a given job and the resource usage variables of other jobs in a multiprogramming environment. This analysis was performed in order to: (1) determine the mix and characteristics of jobs which lead to high performance, (2) provide regression equation predictors of performance for given resource utilizations, and (3) provide performance and resource utilization coefficients for use in a linear programming resource allocation model. The linear programming model is used to select an optimum job mix subject to production, resource usage and budgetary constraints. (Author)
