Introduction

The Data Transfer Node (DTN) at Rice facilitates the movement of data into and out of the "/work" shared filesystem available on DAVinCI, STIC, and Blue Biou and scratch filesystems available on DAVinCI "/dascratch", Blue Gene/P "/bgpscratch", and Blue Biou "/gpfs-biou". It provides massively parallel file transfers so facilitate moving large data sets efficiently. You will be able to move data between participating institutions available via Globus. Additionally, if you install and configure the Globus Connect software you will be able to transfer files using your local computer as an Endpoint.

Prerequisite for Using This System

You must have a globus online account.

You must read the relevant quick start guides on https://www.globus.org/

You must have a cluster account.

Using Globus to transfer files

You will utilize the Endpoint named: rice#dtn

Your Path destination or source will be in either the "/work" shared filesystem available only on DAVinCI, STIC, and Blue Biou or "scratch" shared filesystems available on DAVinCI, Blue Gene/P, and Blue Biou. Minimally to receive or send data you will need to pick a subdirectory with which you have read and write access. For "/work" this will be a subdirectory you create under your sponsor's netID directory within "/work". When using the respective "scratch" directory use a subdirectory you have created. Use "/" for your Path to see all of the filesystems currently available.

To utilize your netID credentials with globus please do the following:

  1. Go to https://www.globusonline.org/SignUp and create a globus online account.
  2. Once the account is set up and you are logged in, click on your user id on the top right and then click on "manage identities"
  3. Select "Add External Identity" and for the account provider select "InCommon/CILogon"
  4. On the CILogon page choose "Rice University" as your identity provider
  5. On the Rice page enter your netid and password and you're done

To test it out, log out of globus online, then go to https://www.globusonline.org/SignIn and select "alternate login" and choose "InCommon/CILogon" or go directly to https://www.globusonline.org/SignIn#provider=cilogon.org Click proceed and on the Rice page enter your netID and password and you should be logged into globus online.

The DTN has jumbo frames enabled. A transfer using a jumbo frame enabled Internet2 Endpoint will take advantage of that during transfer.
