trace driven analysis of a batch processing system
A trace-driven model was used to study a simple processing system which receives batches of jobs from a number of remote terminals. Analysis indicated that the elimination of batching would not harm performance, and that the replacement of the current FIFO job selection rule by more sophisticated ones would lead to improved performance. The development of the model is discussed in some detail. The trace modelling approach avoided much of the statistical analysis needed for traditional simulation models. It is suggested that this technique should be more widely used for system tuning studies.
