Automatic generation of a software performance model using an object-oriented prototype
Curtis E. Hrischuk, Jerome Rolia, C. Murray Woodside · 1995
Early performance estimates for a new software system aid the design process by providing feedback when design decisions can be easily revised. Unfortunately, constructing a performance model of a distributed and concurrent software system can require significant effort. We propose an approach that reduces the model building effort by providing easy specification of performance test cases, empirical estimates for model parameters, automated model generation, and support for different types of models. A prototype is used to describe an object-based system, for which causal traces (angio traces) are recorded during execution. The traces are then processed into sequences of resource demands (workthreads), aggregated into system execution descriptions (workthread classes), and combined to generate performance models. The technique can also be applied at other stages of the development process, Including the redesign of existing software.>
