OPPSI : A Performance Prediction Tool for Parallel Systems
Pierre Cubaud, Nihal Pekergin, H. Castel Taleb · 1994
We describe a specialized modeling tool based on a new model of synchronized activities, which is a superset of Queuing Networks. The tool includes a graphical user interface, a simulator and a range of analytical solvers. INTRODUCTION The study of quantitative models for workloadarchitecture (in)adequacy is of central importance in the context of parallel and distributed programming. It is a very active field in the modeling community (Gelenbe 1989). New models, that generalize the classical Queuing Network approach, are developed in order to include both concurrency and synchronization primitives. These models exhibit a very rich dynamic and scarcely lead to an easy analysis, such as Product Form results. The OPPSI (Outil de Prédiction de Performance des Systèmes Informatiques) project is an attempt to take this evolution into account for performance prediction tools. Started in 1990 as an enriched version of the ARCHISSIME tool (Pekergin 1991), OPPSI is also inspired by the ESPRIT ...
