The large number of processors in high performance computing and distributed applications is becoming a major challenge in the analysis of the way an application's processes communicate with each other. In this paper, we propose an approach that facilitates the understanding of large traces of inter-process communication by extracting communication patterns that characterize their main behavior. Two...
Software maintenance is perhaps one of the most difficult activities in software engineering, especially for systems that have undergone several years of ad hoc maintenance. The problem is that, for such systems, the gap between the system implementation and its design models tend to be considerably large. Reverse engineering techniques, particularly the ones that focus on design and architecture...
We present in this paper a unified paradigm for the verification and validation of software and systems engineering design models expressed in UML 2.0 or SysML. This paradigm relies on an established synergy between three salient approaches, which are model-checking, program analysis, and software engineering techniques. To illustrate the accomplishment of our results, we have designed and implemented...
