摘要 KD-50-I是第一台采用国产龙芯2FCPU的万亿次高性能计算机.在KD-50-I中,所有的计算单元采用无盘结构,启动时需要通过网络从服务器上下载内核并启动之.为达到该目的,需要修改龙芯的BIOS程序(龙芯使用的BIOS基于一款经过修改的叫做PMON的开源软件)以使之在完成系统初始化工作之后,自动完成下载内核并启动等工作.为此我们为PMON开发了RTL8169千兆以太网卡驱动程序,并修改了其初始化流程.本文介绍PMON中RTL8169网卡驱动程序的实现情况,利用tftp协议实现网络启动的情况,KD-50-I中的文件系统架构以及KD-50-I上的BLAS库优化情况等. In KD-50-I, all computing units are diskless. So when boot the high performance computer, all units need to download operation system kernel form some servers. To do this, the BIOS of LoongSon CPU should be modified and some driver program should be added to the BIOS so that all units can do download and boot work automatically. In this paper, we introduce the implement of the diskless boot technology and the file system architecture in KD-50-I.
