默认你是装上auto-complete插件了， 现在好像是1.3，自己去网上下一个。
主要说一说今天的主角etags吧
下载etags代码补全插件
git https://github.com/whitypig/auto-complete-etags.git
将auto-complete- etags.el拷贝到自己的emacs插件加载目录，我自己的是~/.emacs.d/mylisps。然后在你的.emacs添加：
(defun my-c-mode-common-hook-func () (interactive) "Function to be called when entering into c-mode." (when (and (require 'auto-complete nil t) (require 'auto-complete-config nil t)) (make-local-variable 'ac-sources) (setq ac-sources '(ac-source-words-in-same-mode-buffers ac-source-dictionary)) (when (require 'auto-complete-etags nil t) (add-to-list 'ac-sources 'ac-source-etags) (setq ac-etags-use-document t))))(add-hook 'c-mode-common-hook 'my-c-mode-common-hook-func)
当然你要有tags文件了 M-x eshell find . -name "*.[chCH]" -print | etags -
你可以它定义别名在~/.eshell/alias添加：
alias TAG find . -name "*.[chCH]" -print | etags -
好了，基本上大功告成了，剩下就是加载tags文件了，使用M-x visit-tags-table你也可以结合代码段不全插件yasnippet
需要的软件包：
1> mpi运行环境，这里我们使用的是：mpich2-1.5.tar.gz
2>矩阵库GOTOBLAS，我们使用的是：GotoBLAS2-1.13.tar.gz
3>linpack测试软件包：hpl-2.1.tar.gz
安装过程：
1> GOTOBLAS2代数库的安装
