Parallel and Distributed Simulation From Many Cores to the Public Cloud
In this paper, the authors will firstly review some basic simulation concepts and then introduce the parallel and distributed simulation techniques in view of some new challenges of today and tomorrow. More in particular, in the last years there has been a wide diffusion of much cores architecture and they can expect this trend to continue. On the other hand, the success of cloud computing is strongly promoting the "Everything as a service" paradigm. Is parallel and distributed simulation ready for these new challenges? The current approaches present many limitations in terms of usability and adaptivity: there is a strong need for new evaluation metrics and for revising the currently implemented mechanisms.
