As stated above marylou and marylou2 are compute servers. They essentially have the same software and resources available, they are just two different computers. If the account requires access to a graphics head, the account will be created on marylou1. Very few users have the need for an account on all 3 systems. To apply for an account submit this online form .
All accounts have an expiration date.
10 days before expiration an email is sent to notify the user. If the account expiration needs to be extended the user need only send an email to the administrator with information about current use and justification for continued need. If the administrator does not receive any email from the user, the account will be deleted 10 days after the expiration date. Mentors accounts will remain active as long as students under the mentor have a valid account. It is appropriate to mention here that despite the magnitude of computing power of these systems, their capabilities are still finite.
