Performance prediction for parallel applications running on HPC architectures through Petri net modelling and simulation

The paper presents the development of a model and a simulation technique for the prediction of the performance of a concurrent application running on a HPC architecture. Models for the hardware and software were developed using the Coloured Petri Net formalism and then coupled for the simulation. Timed simulations were performed in the Coloured Petri Net tools environment and in the Charm++ respectively the BigSim simulator. The results of both simulations for the same optimization problem show similar trends.
