互连网络布线Open Shop调度算法的一个关键改进

A Critical Improvement On Open Shop Scheduling Algorithm For Routing In Interconnection Networks

Stavros Birmpilis, Timotheos Aslanidis

摘要:

在过去的几年里,互连网络已经被经常使用,特别是在并行化至关重要的应用中。通过这种网络传输的消息包可以使用缓冲区中断,以最大限度地提高网络使用率,并最大限度地减少所有消息到达目的地所需的时间。然而,抢占一个数据包将导致拓扑结构的重新配置,从而在时间成本。通过这样的网络调度消息分组的问题被称为PBS,并且已知是NP困难的。在本文中,我们改进了,关键,多项式可解的情况下,开放式商店的变化,以近似PBS。我们结合这些变化,并呼吁诱导算法IHSA,改进的混合调度算法。我们进行了实验来建立IHSA的效率,并发现在所有使用的数据集中,它产生的时间表非常接近最优。此外,我们还使用非均匀分布的数据集对IHSA进行了测试,并提供了更好的统计数据来说明其性能。为了进一步确定IHSA的效率,我们进行了测试,将其与SGA进行了比较,SGA是另一种在过去测试时取得了出色结果的算法。

英文摘要:

In the past years, Interconnection Networks have been used quite often and especially in applications where parallelization is critical. Message packets transmitted through such networks can be interrupted using buffers in order to maximize network usage and minimize the time required for all messages to reach their destination. However, preempting a packet will result in topology reconfiguration and consequently in time cost. The problem of scheduling message packets through such a network is referred to as PBS and is known to be NP-Hard. In this paper we have improved, critically, variations of polynomially solvable instances of Open Shop to approximate PBS. We have combined these variations and called the induced algorithm IHSA, Improved Hybridic Scheduling Algorithm. We ran experiments to establish the efficiency of IHSA and found that in all datasets used it produces schedules very close to the optimal. In addition, we tested IHSA with datasets that follow non-uniform distributions and provided statistical data which illustrates better its performance.To further establish the efficiency of IHSA we ran tests to compare it to SGA, another algorithm which when tested in the past has yielded excellent results.
