项目摘要

With the continuing advances in VLSI technology, multiprocessor systems with tens to hundreds of processing elements are expected to rival today's supercomputers in the next decade. Systems consisting of a few tens to a million processing elements have indeed been described in the literature. The development of such large scale systems will make numerous applications such as multi-media, computer vision, and modeling of physical phenomena to be feasible on desk-top workstations. However, a major issue in designing large scale multiprocessor systems is the construction of a flexible interconnection network to provide efficient inter-processor communication.This research develops a hierarchically structured interconnection network, 'Tori connected mESHes' (TESH), which allows exploitation of computational locality as well as modular future expansion. Also, the network has reduced wiring and only a few ports per processor, features that are essential in cost-effective implementation of large scale computing systems. Further, it has a regular structure which makes addressing of nodes and message routing rather straightforward. The network also appears to permit 3-D stacked implementation. In part, this is due to the far fewer number of vertical wires needed than almost all known multi-computer networks. As is well known, parallelizing a problem is usually application-specific and system architecture dependent. Therefore, several applications such as sorting, merging, FFT, and convolution, have been mapped to the network as paradigms in.

随着超大规模集成电路技术的不断进步，具有数十到数百个处理元件的多处理器系统有望在未来十年内与今天的超级计算机相媲美。在文献中确实描述了由几十到一百万个处理元件组成的系统。这种大规模系统的发展将使许多应用，如多媒体，计算机视觉和物理现象的建模，在桌面工作站上是可行的。然而，在设计大规模的多处理器系统的一个主要问题是一个灵活的互连网络的建设，提供有效的处理器间的communication.This研究开发了一个层次结构的互连网络，'托里连接mESHes'（TESH），它允许利用计算的局部性以及模块化的未来扩展。此外，该网络减少了布线，每个处理器只有几个端口，这些特征在大规模计算系统的成本效益实现中是必不可少的。此外，它具有规则的结构，这使得节点的寻址和消息路由相当简单。该网络似乎还允许3-D堆叠实现。部分原因是，与几乎所有已知的多计算机网络相比，所需的垂直线路数量要少得多。众所周知，并行化问题通常是特定于应用程序和系统架构的。因此，排序、合并、FFT和卷积等应用程序已作为范例映射到网络中。
