So you got a whole bunch of data that's sitting on your hard drive or somewhere else, and you need it on hoffman2. How do you get that gigs and gigs of data onto the cluster? Sorry there's no magical genie that instantly does it for you. You're going to have to slowly transfer it through your network on to Hoffman2. PLEASE NOTE: TRANSFER IS ONLY AS FAST AS YOUR INTERNET CONNECTION!
Here's several ways of pushing that cow up the hill.
Globus Online
Globus Online is a tool that abstracts a lot of complexity from the data transfer process. It is a GUI system that is capable of starting a transfer, having the internet connection broken and re-established, and then continuing and finishing the transfer automatically.
It is the fastest way to transfer data to Hoffman2 because it has a faster connection than other Hoffman2 nodes.
For more information, see the ATS instructions here Globus Online
scp

sftp
Another command line tool that uses secure encrypted channels. There are also GUIs that use this protocol (like Cyberduck or Filezilla).

rsync
