Using slurm cluster computing node debugger in vscode

problem

The problem is vscode When debugging in the cluster, you cannot automatically enter compute node, But stay in login node

• Suppose you have passed vscode Remote connection server

Solution

• 1 Through the command ssh To the cluster ssh cluster
• 2 In the cluster authorized_keys add to Local laptops or desktops Of public key
  • （windows The path of the system is C:\Users\yourusername\.ssh\id_rsa.pub , If not, you can pass through the terminal ssh-keygen -t rsa Command to generate , Just press enter ）
  • （ In the cluster authorized_keys stay ~/.ssh/authorized_keys）
• 3 Get computing resources from the cluster , That is to ensure that you are under the login node ssh gpunode Was a success
• 4 Get the name of the computing node , Let's say it's gpunode
• 5 edit Local laptops or desktops Of config file

#  Name the login node casually 
Host loginnode
	#  Of the login node  ip
    HostName 127.0.0.1
    #  The user name of the login node 
    User lihua 
    #  Of the login node   port 
    Port 22
#  The name of the computing node can be chosen randomly 
Host computenode
	#  there  name  It is you who can pass through at the computing node  ssh gpunode Direct entry 
    HostName gpunode
    #  The user name of the login node 
    User lihua
    #  Login node name , Keep up with the above 
    ProxyJump loginnode

Then you can connect directly to the computing node locally ！ In this case, there is no debug It is still the trouble of logging in to the node

Conclusion
