Accounts and logging in

How do I request an O2 account?

...

All cluster logins from outside the HMS network require two-factor authentication. For more details, please reference Two Factor Authentication on O2 and Two Factor Authentication FAQ. Please contact us if you are having trouble with two-factor authentication on O2. 

Please do NOT send us or anyone else your password. Ever. We can assist you without knowing your password, and sharing accounts on the cluster is prohibited by Harvard security policy.

If you're having difficulty logging in to O2, make sure you're using your HMS account (in lowercase) and HMS account password to log in. If that does not resolve the problem, you can reset your HMS account password. Contact the HMS IT Service Desk (itservicedesk@hms.harvard.edu, or 617-432-2000) if you're unable to login to the HMS account management website. Your HMS account may have been locked due to too many failed login attempts to the O2 cluster. Once you are able to login to the HMS account management site, wait 1 hour and try logging in to O2 again. If you're still facing problems, then send in a ticket to us.

Where can I put my data?

...

Please keep in mind that we do not recommend using GUI applications (like the graphical mode of Matlab) on the O2 cluster, as you can experience laggy performance as graphics are forwarded over X11 in real time. 

Why did I receive an email that says my priority will be/was lowered due to inefficient jobs?

Please check our wiki page Improving O2 Efficiency for more information.
