本文描述了CRAY T3E多处理机中使用的互连网络。该网络是一个双向的3D环面，具有完全自适应的路由、优化的虚拟通道分配、集成的屏障同步支持和相当大的容错性。这些路由器采用LSI的500K ASIC技术，带有定制的发射器/接收器，以375 MHz的频率驱动低电压差分信号，链路数据有效载荷容量约为500MB/S。
This paper describes the interconnection network used in the Cray T3E multiprocessor. The network is a bidirectional 3D torus with fully adaptive routing, optimized virtual channel assignments, integrated barrier synchronization support and considerable fault tolerance. The routers are built with LSI’s 500K ASIC technology with custom transmitters/ receivers driving low-voltage differential signals at 375 MHz, for a link data payload capacity of approximately 500 MB/s.
