License Management
ATN has contracted with specific vendors to provide commercial software for use by UNC affliates. Many of these programs aid users in research and are a vital components of ATN's Statistical, Scientific, and BioScientific services. Others are requested by particular departments. Many times the contract will specify a maximum number of seats (instances of the program) can be run at a specific time; the vendors will usually provide a piece of software, called a license daemon, that makes sure that this is the case. When a user invokes the licensed program, the program contacts the license daemon to make sure its instantiation won't surpass the maximum number of seats. One of the DCI's components is a license server that runs these license daemons, allowing users to execute the commercial programs for which ATN has a site license. This centralized management of licenses along with binaries that reside in AFS space and load sharing facilities allow a true distributed computing environment. Within this environment, any unix user can run a program which ATN has a site license off any participating machine (whether it be their own personal unix station or one of the publically available machines) and distribute the processes to other "work horse" machines. |
