Abstract

This is Part 2 of a trio of works intended to provide a unifying framework in which conservative and optimistic synchronization for parallel discrete event simulations can be freely and transparently combined in the same logical process on an event-by-event basis. In this article, we continue the outline of an approach called Unified Virtual Time (UVT) that was introduced in Part 1, showing in detail via two extended examples how conservative synchronization can be refactored and combined with optimistic synchronization in the UVT framework. We describe UVT versions of both a basic time windowing algorithm called Unified Simple Time Windows and a refactored version of the Chandy-Misra-Bryant Null Message algorithm called Unified CMB.

虚拟时间III，第2部分：结合保守和乐观同步

这是三项工作的第2部分，旨在提供一个统一的框架，在该框架中，并行离散事件模拟的保守和乐观同步可以在同一逻辑过程中逐个事件自由透明地组合。在本文中，我们继续介绍第1部分中介绍的一种称为统一虚拟时间（UVT）的方法，通过两个扩展示例详细展示了如何在UVT框架中重构保守同步并将其与乐观同步相结合。我们描述了称为统一简单时间窗口的基本时间窗口算法和称为统一CMB的Chandy Misra Bryant空消息算法的重构版本的UVT版本。

期刊介绍： The ACM Transactions on Modeling and Computer Simulation (TOMACS) provides a single archival source for the publication of high-quality research and developmental results referring to all phases of the modeling and simulation life cycle. The subjects of emphasis are discrete event simulation, combined discrete and continuous simulation, as well as Monte Carlo methods. The use of simulation techniques is pervasive, extending to virtually all the sciences. TOMACS serves to enhance the understanding, improve the practice, and increase the utilization of computer simulation. Submissions should contribute to the realization of these objectives, and papers treating applications should stress their contributions vis-á-vis these objectives.
