CAREER: Parallel Discrete Event Simulation: Protocols, Tools and Applications

即使在最先进的工作站上，许多离散事件系统的详细仿真也往往很慢。 并行离散事件仿真（PDES）技术提供了一种替代方案，以加快这种模拟。 然而，PDES是一个难题。 大多数模拟的不规则性和数据依赖性使得同步成为一个困难的问题。 在这个职业生涯项目中，将采取跨学科的方法来解决这个问题。 一类新的"自适应"协议将开发集成在一个框架中的几个机制，自动实现最佳性能，尽管大多数模拟的动态性质。 目标平台是由工作站或可能的多处理器组成的网络，通过高速网络连接。 几个创新计划在这样的平台上的PDES内核的协议开发和实施。 其中包括考虑平台的多粒度和使用快速的用户级消息传递支持。这项工作将侧重于电信和计算机网络的模拟。

Detailed simulation of many discrete event systems is often slow even on state-of-the-art workstations. Parallel discrete event simulation (PDES) techniques offer an alternative to speed up such simulations. However, PDES is a hard problem. The irregular, data-dependent nature of most simulations make synchronization a difficult issue. In this CAREER project an inter-disciplinary approach will be taken to address this problem. A new class of "adaptive" protocols will be developed that integrates several mechanisms in a single framework, to achieve optimal performance automatically, notwithstanding the dynamic nature of most simulations. The target platform is a network of workstations or possibly multiprocessors, connected by a high-speed network. Several innovations are planned regarding protocol development and implementation in a PDES kernel on such platforms. These include accounting for the multi-granular of the platform and use of fast, user-level messaging support. The work will focus on simulating of telecommunication and computer networks.
