Back to all things Hoffman2

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.

Create a Globus Account

First you need to create a free, Globus account (one-time):

  • Point your browser at http://www.globus.org and click Sign Up.
  • On the Create an Account page, fill in the information (your name, email address, username, password, etc.) and read the terms, then click Register.

You will receive an email with a link which you need to follow to confirm your new Globus account.

sftp

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

Log in to the server, then punch in your password when prompted and you'll be logged in.

rsync

Implied in the name, syncs folder/files between filesystems. It also makes use of secure encrypted channels.

to upload /PATH/TO/SRC/FILES/HERE from your local machine to your home directory on Hoffman2
