Intel AI Cloud 使用

 1.申请AI Cloud

  A ‘training-ready’ hardware like Amazon® EC2, Intel® AI DevCloud, or a GPU-based system pre-installed with Caffe - Installation instructions

  

  提交信息后约一个工作日即可收到审核通过的邮件

 2.Jupyter的使用

  申请审核通过后即可在https://access.colfaxresearch.com/?p=connect#sec-jup查看账号和密码,通过hub.colfaxresearch.com进行登陆

 3.SSH登陆云服务器

 sudo apt-get install ssh

  下载Linux access key到本地~/Downloads/

 cd ~
 mkdir .ssh
 cd ~/.ssh/
 vi config

  在登陆页面将https://access.colfaxresearch.com/?p=connect#sec-jup的配置信息拷贝到config文件中,例如(以网页上的数据为准)

  Host colfax
  User u14673
  IdentityFile ~/Downloads/colfax-access-key-14673
  ProxyCommand ssh -T -i ~/Downloads/colfax-access-key-14673 guest@cluster.colfaxresearch.com

  配置执行权限

  chmod 600 ~/Downloads/colfax-access-key-14673
  chmod 600 ~/.ssh/config

  首次登陆时在terminal中输入如下命令,随后选择yes,出现welcome to intel AI dev Cloud 时即为登陆成功

  ssh colfax
  ########################################################################
  # Welcome to Intel AI DevCloud!             
  ########################################################################

    可能出现的运行错误

  Error1:ssh:  Could not resolve hostname colfax: Name or service not known
  基本上是由于运行账户与配置文件的创建账户不一致造成的,mkdir .ssh 和 vi config 时不要加sudo

   Princles

  ①do not run jobs on the login node and use qsub directives.
  ②In the same folder,create a file
"myjob",add the following three lines.    #PBS -l nodes=1:ppn=2  cd $PBS_O_WORKDIR    python my_application.py
  ③can submit this job with    qsub myjob
  ④track the job with    qstat          cat myjob.oXXXXXX    cat myjob.eXXXXXX   ⑤Running Multiple Jobs    If resources are available, all
4 jobs will start at the same time on different compute nodes.

 4.文件拷贝

  [myname@myhomecomputer ~] scp /path/to/local/file colfax:/path/to/remote/directory/
  [myname@myhomecomputer ~] scp colfax:/path/to/remote/file /path/to/local/directory/

  拷贝文件和拷贝文件夹的差异在于scp 是否加 -r ,即scp -r

 5.软件安装

  If you need to install a dependency, please put it in your home directory.
  * For autotools, you can do it with "./configure --prefix=~/my-path"
  * For Python packages, use "pip install package_name --user".  

   6.Caffe的使用

  BIN=/glob/intel-python/python3/bin
