Resource Sharing in Performance Models

In software systems, individual components interact not only through explicit function invocations, but also through implicit resource sharing. The use of shared resources significantly influences the duration of the invoked functions. For resources that are heavily shared, capturing this influence can lead to performance models that have a large number of elements and a large number of dependencies. We introduce an approach that can model resource sharing separately from function invocations, keeping the performance model reasonably simple while still describing many of the effects of resource sharing on the duration of function invocations. The approach has been tested on the CoCoME component application modeling example.
