摘要

只提供摘要形式。我们提出了APENet,一种新的高速,低延迟,三维互连架构,针对运行lqcd类数值应用的PC集群进行了优化。硬件实现基于单个PCI-X 133MHz网络接口卡,承载6个独立的双向通道,每个方向的峰值带宽为676 MB/s,测量延迟小于10 /spl mu/s。网卡的内部分组交换功能允许多达三对链路同时活动。当前的软件环境是基于Linux的,由底层库和高层应用库组成。目前正在积极开发MPI实现和网络设备驱动程序。

APENet: a high speed, low latency 3D interconnect network
Summary form only given. We present APENet, a new high speed, low latency, 3-dimensional interconnect architecture optimized for PC clusters running LQCD-like numerical applications. The hardware implementation is based on a single PCI-X 133MHz network interface card hosting six independent bidirectional channels with a peak bandwidth of 676 MB/s each direction and measured latency less than 10 /spl mu/s. The internal packet switching capabilities of the network card allows up to three couple of links simultaneously active. The current software environment, based on Linux, is made of a low-level library and a high-level application library. An MPI implementation and a network device driver are being actively developed.
