Language support for parallel discrete-event simulations

A number of algorithms have been developed to support parallel execution of discrete-event simulation models. In general, these algorithms are complex and implementing them directly in a simulation model is a difficult and resource-intensive programming task. Parallel simulation languages and environments can be of considerable help in hiding the complexity of the underlying synchronization algorithm and in providing a simpler virtual machine to the model designer. This paper is a survey of currently available software tools that facilitate the design of parallel discrete-event simulations.
