Math GLUE overview

The new Mathnet leverages campus Linux/Unix resources which are sometimes referred to on campus as Glue or TerpConnect. Campus maintains a general web page for TerpConnect [1]. 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 will be running Red Hat 6. Red Hat 6 is quite new which has a lot of advantages (like recognizing the new Math hardware properly) but we are among the first Glue Red Hat 6 users so we will likely run into a few issues that no one else has experienced. Glue supports Gnome, KDE, and fvwm as window managers. We recommend using Gnome as we have spent the majority of our time testing in that environment.

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 new 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 new system leverages your campus directory ID and password. In some cases, this user ID is different than your Mathnet ID. During the transition, you will need both accounts but once we have completely transitioned off the current Mathnet, your Mathnet ID will no longer be needed. This will likely take 6-12 months although you may find that you don't use your Mathnet ID at all after you move to the new system.

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.

If your Mathnet ID is different from your directory ID, your Mathnet ID will still function for email@math.umd.edu. For instance, if your Mathnet ID is joe and your directory ID is joecool, email sent to joe@math.umd.edu will still function after the current Mathnet has been retired even though the ID joe is no longer used for anything.
