All O2 cluster logins from outside of the HMS network require two-factor authentication. O2 logins require an HMS profile with DUO, which is different than the DUO profile used for Harvard Key. Please see:
O2 logins use HMS Account login credentials (formerly known as eCommons ID). If needed, there is a self-service portal to reset your password or unlock your account. Passwords can not be changed from the O2 command line, even if you are ever prompted to do so.
If the self-service portal does not work, please contact the HMS IT Service Desk for assistance.
Please login to O2 using a SSH (secure shell) application. You MUST use only lower case letters in your username for O2 logins!
To get started using O2, e.g. running jobs and copying your data to the environment, please first review the main O2 documentation page.
This includes a "Basic guide to using the Slurm job scheduler" and other important information for new users.
The O2 Portal web interface
The O2 Portal, powered by OSC Open OnDemand software, is a web interface that allows you to access and use the O2 cluster from your web browser. From the O2 Portal, you can view the status of your jobs, edit and transfer files, start an O2 login shell, run GUI applications such as MATLAB, RStudio, Jupyter, and more. It’s a great tool for researchers who want the power of O2 without having to use a command line interface.
For future issues or software installations, please submit a request to us by emailing email@example.com . This will open a support request and a member of the Research Computing team will get back to you.
While you can contact RC at any time, the team also holds Office Hours every Wednesday, 1 - 3 PM.
