Abstract

This paper introduces a new high-level parallel programming construct called multiLoop that is designed to extend existing imperative languages such as C and Java. A multiLoop statement translates to SPMD specification of a named group of synchronous-iterative processes. For efficient iterative communication, multiLoop provides a new publish/subscribe model of shared variable access. Under this model the sequential consistency of shared memory is maintained by a new, simple and efficient adaptation of virtual time paradigm. Virtual time is a localised message tagging and queuing procedure that provides a highly efficient alternative to barrier calls. ML-C, a prototype implementation based on C has been developed. We describe the programming model, discuss its implementation and present some empirical data showing good performance obtained for an example of the target class of applications.
MultiLoop编程结构
本文介绍了一种新的高级并行编程结构,称为multiLoop,旨在扩展现有的命令式语言,如C和Java。multiLoop语句转换为指定的一组同步迭代过程的SPMD规范。为了实现高效的迭代通信,multiLoop提供了一种新的共享变量访问的发布/订阅模型。该模型通过对虚拟时间范式的一种新的、简单有效的适应来保持共享内存的顺序一致性。虚拟时间是一个本地化的消息标记和排队过程,它提供了屏障调用的高效替代方案。ML-C是一个基于C语言的原型实现。我们描述了编程模型,讨论了它的实现,并给出了一些经验数据,显示了目标类应用程序的良好性能。
