In optimistic simulations, Global Virtual Time (GVT) is considered to be the fundamental synchronization concept. During the recent years, a number of methods have been proposed for determining GVT, however most of these methods have been found to either focus on specific types of simulation problems or assume specific hardware support. In this study, the GVT problem is addressed in the context of scalability, efficiency, portability, flow control, interactive support and real time use. Additionally, a new GVT algorithm called SPEEDES GVT that provides flow control by processing events risk-free while flushing out messages during the GVT computation is proposed.
