Download Putty SSH Client executable and run it.

Depending on the cluster used, enter your username and the cluster link in the following format in Field #1::

• M4000 Cluster: hpcxxxx@carlm4k.hpcvl.carleton.ca
• SunFire6800: hpcxxxx@sfnode0.hpcvl.carleton.ca

You can assign a name to each cluster in Field #2 and save it (#4).

Use the load botton (#3) to connect to a desired cluster selected from the list of saved hosts.

You would need to provide your login password in the next window.
