GLUE leverages campus Linux/Unix resources which are sometimes referred to on campus as Glue or TerpConnect. Campus maintains a general web page for TerpConnect . There are a lot of general campus items on the TerpConnect page but there are a few more specific links on the page that may be useful if you have a chance to check it out. For those hard core users that want to know more details, you can visit the Glue wiki (requires campus directory authentication) at http://www.glue.umd.edu/wiki.
Glue/Terpconnect supports SPARC Solaris as well as Red Hat. All Math machines run Red Hat 6. Glue supports Gnome, KDE, and fvwm as window managers. We recommend using Gnome as it receives the most use and is what we test against when doing updates and new software installs.
Glue/TerpConnect allows for multiple versions of the same application to be installed. For instance, Mathematica and Matlab both have older and newer versions available. This allows users to select the version that they prefer to use and it makes it easier to stay up to date since newer versions won't require everyone to switch and risk having some change break some important ongoing work.
The Glue system offers access to most applications through menus but you can also easily run applications from the command line. The system has a command called tap that can be very useful especially for those people who prefer command line to GUI menus.
The Glue system leverages your campus directory ID and password. It is possible that when you first created your campus directory ID, you did not activate your Glue/TerpConnect account. This is not a common occurrence but you can visit http://www.oit.umd.edu/new to activate your account.
