Tiger-ARRK

Overview

We share a dedicated login node on Tiger3 called tiger-arrk. It is shared with the  Kingsbury Research Group . Since this is our dedicated login node, we can run background processes on it to our heart's content. The specs for this node are as follows:
  • 2x Intel Xeon Gold 6542Y CPUs
  • 512 GB RAM
  • 2x 480 GB M.2 SSD system drives
  • 4x 480 GB SSDs in RAID10

Connecting

To connect to tiger-arrk, run the following:
ssh <NetID>@tiger-arrk.princeton.edu
You will then be on the login node, which has direct access to the Tiger3 queuing system. Alternatively, you can access the login node via "Clusters > Tiger ARRK Shell Access" at  https://mytiger.princeton.edu .

MongoDB

We have a MongoDB instance that runs on tiger-arrk. See  💽⁠⁠Databases⁠  for details on how to interface with MongoDB in general.
To connect to the MongoDB instance on tiger-arrk with Studio3T, use the following configuration:
  • Authentication
  • Authentication Mode: Legacy (SCRAM-SHA-1)
  • User name: Your MongoDB username (typically your NetID)
  • Password: Your MongoDB password (not your NetID password!). If you don't know this, it probably means you need to ask for an account to be made.
  • Authentication DB: Your database name (typically your NetID)
  • SSH
  • Enable "Use SSH tunnel to connect"
  • SSH Address:  tiger-arrk.princeton.edu 
  • SSH Username: Your NetID
  • SSH Auth Mode: Password (or ideally your private key, if set up)
  • SSH Password (if not using a private key): Your NetID password

GUI Applications

To use GUI applications, your best option is to go to  https://mytiger.princeton.edu  and select "Interactive Apps > Desktop on Tiger3 Vis nodes." From there, you can select the Kingsbury/Rosen Shared Login server.
