Performance evaluation of distributed embedded systems applications via Kahn process networks and ABSOLUT

The modern mobile devices support diverse distributed applications. The rapid deployment of these applications demands brisk system-level performanceevaluation. Abstract workload based performance simulation (ABSOLUT) has been successfully employed to evaluate theperformance of non-distributed applications. The main advantages of ABSOLUT include the use of standard tools and languages for example SystemC and UML2.0. To extend ABSOLUT for the system-level performance simulation of distributed applications, application workload models executed in one device must trigger the execution of corresponding workload models in another device. The main contribution of this article is the application of Kahn Process networks (KPN) model of computation (MOC) to extend ABSOLUT for the system-level performance simulation of distributed applications. The approach is experimented with a case study which employs GENESYS application architecture modelling. The GENESYS adopts a service-oriented and componentbased design for distributed applications. The approach is not limited to GENESYS and can be used for performance evaluation of distributed applications designed via other application design approaches. The UML2.0 MARTE profile, PapyrusUML2.0 modelling tool and SystemC were used for modelling and simulation
