ABSTRACT:
A computer performance modeling system is provided. The modeling system includes a first and a second submodel which simulate system operations of a particular system component in minute and simple detail, respectively. A performance analysis mechanism is operatively coupled to the first and the second submodel to execute a simulation of the particular system component using the first and the second submodel. The performance analysis mechanism has a switching device for switching between the first and the second submodel during the simulation at a predetermined point in the execution of the simulation. In an alternative embodiment, the second submodel derives a specific behavior from simulation statistics collected by the first submodel. Also, the performance analysis mechanism executes a simulation of a system model having several of the particular system components by using a plurality of the first and the second submodels. A method for modeling computer performance also is provided.
