Research in parallel discrete event simulation (PDES) protocols is characterized by a large number of unrelated empirical studies, a small set of analytic studies and to date no realizable approach that is optimal or universally practical. This research project is extending a framework incorporating a low-cost network that supports rapid dissemination of critical synchronization information. Such a framework should, at a minimum, provide speed-ups for all existing protocols. More promising, however, is its potential to support adaptive protocols-those that employ aggressive processing selectively. Among all protocols, these have the greatest likelihood of having provably minimal expected execution times. Success in this research could lead to the construction of PDES engines that would simulate arbitrary applications in minimum expected execution times. Further benefits could be gained from framework-supported, application-dependent performance enhancements based on "look-ahead" and "future lists."

平行离散事件模拟（PDES）方案中的研究的特征是大量无关的经验研究，一小部分分析研究，迄今为止没有最佳或普遍实用的可实现方法。 该研究项目正在扩展一个框架，该框架结合了一个低成本网络，该网络支持快速传播关键同步信息。 这样的框架至少应为所有现有协议提供加速。 但是，更有希望的是它的潜力支持自适应方案 - 选择性地采用积极处理的方法。 在所有协议中，这些协议的可能性最大的可能性很小。 这项研究的成功可能会导致PDE引擎的构建，这些PDE引擎将以最小的预期执行时间模拟任意应用程序。 从基于“ look-head”和“未来列表”的框架支持的，依赖于应用程序依赖的性能增强功能的增强功能可以获得进一步的好处。
