Logging On to Phoenix Clusters: Overview¶
- Logging on and interacting with Phoenix clusters requires the use of a tool called SSH
- Interaction with the Cluster is done through the terminal / command line, and interactive sessions can be started through the terminal after logging in
Log into Phoenix: Using SSH¶
What is SSH?¶
- SSH stands for Secure Shell
- A program for logging into a remote machine securely
- SSH is how you log into and interact with the cluster
Logging Into Cluster - Linux / Mac¶
- To SSH into Phoenix, you MUST be connected to the GT VPN, even if you are on campus!
You must be connected to Georgia Tech VPN to sign in.
- After you are using the GT VPN, open up a new terminal and simply use this template:
ssh email@example.com # Use your GT username in place of "someuser3" # press <return> to run # Must be on GT campus internet or connected to Georgia Tech VPN
In addition to "login-phoenix", you may use "login-p" to avoid spelling out Phoenix when connecting. Run the command
pace-whoami while logged on to the cluster to see all the headnodes you can use.
Next, you will be prompted for a password. Enter your GT password. Note when typing passwords in Linux, the password line will be blank and won't show characters. Press enter to login.
The screen should look like this:
You should be logged into your account on a headnode. You can now interact with the cluster, submit jobs, make files, and do anything else you would do normally on a computer.
- After you have logged in, you should see a screen that looks like this:
- You can still use SSH on windows, but you will need a client. PuTTy is recommended
- After you have installed PuTTy, open it and you should see a screen similar to this one.
- In the
HostNamebar, enter your account address:
firstname.lastname@example.org. Use your GT username instead of "someuser3".
openand in the terminal type in your GT password when prompted for password.
You may see a warning that looks like this: Click "Yes". You can now enter your password. Please note that although you may not see any characters appear when you begin typing your password (this is a security feature), your password input is indeed going through.
- Congratulations! You are now logged into your account on a headnode and able to interact with the Phoenix cluster through the terminal.
