Approach To A Simulation Virtual Machine: Object Oriented Implementation Of Cdevs And Pdevs
ABSTRACT
Advancements in technology, computer design, and architecture have led to larger and more complicated challenges and systems.
Predicting the behaviour of complex systems, such as weather forecasts, fires, floods, earthquakes, nanotechnology, material design, and genome decoding, is challenging due to the large amount of data, high statistical requirements, and global user communities.
Distributing simulation across many processors can minimise execution time, enable real-time execution, and combine simulators.
We propose a virtual machine for Discrete Event System Specification (DEVS) that may simulate a DEVS model on any hardware host, including LAN, WAN, Grid, Cluster, and the Internet. The virtual machine is divided into three layers: modelling, simulation, and middleware.
The modelling layer receives the DEVS model, while the simulation layer uses either the pessimistic or optimistic synchronisation algorithms. The middleware layer maps the simulation to any hardware host.
The virtual machine kernel includes both CDEVS and PDEVS simulator implementations, as well as their distributed versions.
We implemented a PDEVS for an existing CDEVS simulator utilising meta modelling. And finally, we supply the multilayer simulation package.
