OpenScienceGrid

The Open Science Grid (OSG) is "a national, distributed computing partnership for data-intensive research".

Access to OSG's resources provides researchers with an expansive (and free) computing pool.

Getting started​

  1. Ensure you have an active Globus account
  2. Sign up for OSG
  3. Follow the "Quickstart Guide"

SSH Login​

Before users can remotely access the OSG login nodes with ssh, an ssh-key needs to be added to the user's Globus profile. This may take overnight to synchronize.

Globus provides documentation on how to generate SSH keys and how to add them to the Globus ID profile. After the keys are properly set up and synchronized, you can login with:

ssh your_username@login.osgconnect.net

Additional endpoints​

Additional login nodes may be accessed (the above domain defaults to one of these):

  • login01.osgconnect.net
  • login02.osgconnect.net
  • login03.osgconnect.net

Tutorials​

  • An interactive tutorial from the University of Utah.

    • This resource provides a guide to getting started with and using OSG (and its queuing software HTCondor).
    • OSG's login nodes provide tutorial programs that users may run within the shell. The guide runs through several of these, getting more complex with each example. The dag files and submit scripts provided serve as decent templates for new users.

  • User Guide for OSG.

    • This resource provides good computational guidelines as well as some sample scripts.
