-The version of Unix running on the department'​s cluster is HP (Digital/​Compaq) Tru64 Unix.  The Tru64 cluster is in the process of being phased out as Tru64 is nearing the end of its support life.  A cluster of Linux machines replaces it.+

-Wireless network access is provided in some areas of Tate Lab to any user who can authenticate using their University X.500 username and password. The wireless network is logically separate from the departmental wired network, and subject to different security restrictions. Wireless coverage area will be expanded as resources permit. Operation of personal wireless access points is not permitted.
