Windows

Download and install:

• PuTTY
• Xming (Note: disable automatic installation of PuTTY with Xming. The above installer is a newer version)

Getting an Account

HPC-Storrs

HPC facility on Storrs campus are open to all members of the UConn research community. If you haven’t applied one before, you can simply request for an account by clicking “Get an Account”. A new page will pop up to ask for your NetID and password. Your HPC-Storrs account username will be your UCONN NetID and the initial password will also be the same as your NetID password.

Logging onto the Clusters

Follow the instructions below for your system:

Mac OSX

Open “Applications-> Utilities -> Terminal” or “Command+Space” to search Terminal using “spotlight search” In a terminal:

ssh -X NetID@login.storrs.hpc.uconn.edu

Windows

Launch Xming. You will always need to have this open in order to forward graphical windows from the external clusters.

Start PuTTY, and:

• “Session” → “Host Name” username@stampede.tacc.utexas.edu for Stampede and NetID@login.storrs.hpc.uconn.edu for HPC-Storrs
• “Connection” → “SSH” → “X11” check “Enable X11 forwarding”
• Back in “Session”, you can save these settings for next time.

You can start putty several times, if you need several terminal windows; only one instance of Xming needed.

Linux

In a terminal:

ssh -XC NetID@login.storrs.hpc.uconn.edu
