Connecting to HPC Resources

Summary

MSI provides access to a variety of High-Performance Computing (HPC) systems designed to tackle a wide range of computational needs. This document will show you how you can access all of MSI computational resources from your personal computer.
 


Skills/Software Needed

If you are connecting from a computer running Windows OS you may need to download and install PuTTY

OSX and Linux does not require additonal software to connect.

Connecting to MSI

SSH

Your computer will communicate with MSI resources via SSH. More information about SSH

Connecting to MSI with Windows OS

If you are using the most recent version of Windows 10, you can perform basic ssh connections in your Command Prompt application. In this case, you can follow the OSX and Linux instructions below. 

For older versions of Windows, and for running graphical interfaces over SSH, see our PuTTy setup guide.

 

Connecting to MSI with OSX

Terminal is a preinstalled application which can be used to connect to MSI systems. Terminal can be found in the Utilities folder found in the Applications folder. 

Connecting to MSI with Linux OS

Terminal is a preinstalled application which can be used to connect to MSI systems. 

Connecting to Mesabi or Mangi 

Once you open the Terminal App or PuTTy type:

ssh yourMSIusername@resourcename.msi.umn.edu

replacing yourMSIusername with your MSI username and resourcename with the MSI resource that you wish to connect to (such as mesabi, mangi, etc).

  • You will be prompted for your MSI password. Type it in then press enter. The terminal will not display your password as you type. 
  • The first time you log into MSI systems you will be asked if you would like to cache the server fingerprint. Type yes and press enter.
  • Note: You should be connected to the eduroam network or the UMN VPN for this command to be successful.

  • You are now connected to the MSI system denoted in your original command. 

Moving between MSI Systems

MSI prohibits moving directly from one system to another. For example, if you are connected to Mangi and would like to connect to Mesabi you will need to either:

  • exit out of your current session using the exit command, and then ssh to the new system (see the image below), OR
  • begin a new ssh session in another terminal/PuTTY window.

 

  • Each time you move between systems you will see the welcome message associated with the system you are connecting to. These messages often contain useful information and should be read. 
  • NOTE:  Mangi and Mesabi have specific nomenclatures in the prompt. When connected to Mangi your prompt will contain ln1 followed by some numbers, and when connected to Mesabi your prompt will contain ln0 followed by some numbers. This is a quick short cut to remind you which system you are connected to at any time.
